}Crypto market data for AI agents (liquidations, funding, open interest, prices), Solana pre-trade checks, OFAC sanctions screening, scholarly papers, utilities and fixed-purpose language tasks (OCR, translate, summarize, extract, classify, prompt-injection check, transcribe). Pay per call in USDC. No accounts, no subscriptions, and no API key needed (prepaid keys are optional, for bots that cannot pay x402).
AgentFeed sells live trading data through the x402 payment protocol on Solana, Base, Polygon, Arbitrum, Arc, Optimism, Monad and Avalanche, and on request on Celo, HyperEVM, Unichain, Scroll, SKALE Base, BNB Chain, Ethereum, Robinhood Chain, World Chain, Sei and X Layer (GET /api/<route>|<network>). An agent hits an endpoint, gets a 402 Payment Required with the price, pays a fraction of a cent in USDC (or the dollar token the network names) from its own wallet, and receives the data — in about two seconds, gas sponsored by the facilitator.
Two rails, same data:
We run our own liquidation collector across Bybit, OKX and Binance — every USDT-margined perpetual on all three, recorded continuously since 2026-07-08.
The size of that tape is not a claim, it is a query. Measured 2026-09-28 06:56 UTC:
It grows while you read this: the row count above and the one you get from the same query five minutes later will not match.
The 7-day figure is published live by the service itself at
/ under coverage.perp_markets_7d, recomputed from the tape
rather than restated, so this README can be checked against it rather than believed.
This data cannot be bought. Not from us, not from anyone:
liquidationSnapshot no longer exists on
data.binance.vision — the directory is an empty shell. Verified 2026-07-12.There is no public historical liquidation dataset for any major venue, at any price. The only way to hold this data is to have been recording it.
Being straight about this matters more than the marketing:
Binance and OKX rows are a structural undercount, and the undercount is worst during cascades — exactly when the data matters most. This is true of every liquidation dataset on the market, including the well-known ones. Most don't say so.
Bybit rows are the highest-integrity part of the dataset. Weight accordingly.
side field, which most datasets get wrongThree exchanges, three conventions. We normalize all of them:
S is already the position side (Buy = a long was liquidated). Passed through.S is the order side — a SELL order is what closes a long. Flipped.posSide explicitly. Mapped.In our output: Buy = a LONG was liquidated. Sell = a SHORT was liquidated. Invert this
and every long/short ratio you compute is backwards for some venues.
Notional uses filled_qty × avg_fill_price — what actually executed — not limit_price × requested_size.
Every paid route, cheapest question last. Generated from
/.well-known/x402.json,
read 2026-11-01 — names, prices and routes are the manifest's, not a copy kept
in sync by hand. What each one returns is under
102 tools, word for word as
the service publishes it.
Every paid route answers 402 with an x402 v2 challenge in the PAYMENT-REQUIRED header, and
the same challenge as an x402 v1 body ({x402Version: 1, accepts}) for Base and Solana. Pay with
PAYMENT-SIGNATURE (v2, any rail) or X-PAYMENT (v1 on Base or Solana, verified and settled
through the CDP facilitator's v1 kinds; Polygon and Arbitrum have no v1 kind there and stay v2).
Eight networks are in every 402 and eleven more are offered on request (see "Pay on any chain"); Algorand is built but switched off, see "Algorand is switched off" below. Each network is settled by
exactly one facilitator: CDP for Solana, Base, Polygon, Arbitrum and World Chain; Circle's Facilitator Service for Arc, to a
dedicated Arc address; GoPlausible for Algorand (switched off); Ultravioleta for Optimism, Monad, Avalanche, Celo, HyperEVM, Unichain, Scroll,
SKALE Base, BNB Chain, Ethereum and Robinhood Chain; PayAI for Sei and X Layer. payments.js gives each facilitator client only
its own networks, so a payment on one network can never reach another's facilitator.
Every paid route also carries MPP tempo/charge challenges in WWW-Authenticate (Tempo
mainnet, chain 4217, OUSD first, then USDC.e, at the route's price; no fee payer, the payer pays
gas). Only signed transactions (pull mode) are accepted: the server validates the transfer, runs
the request, and broadcasts it only when the response is below 400, so a failed call is never
charged; an already-broadcast hash credential is refused. /api/sol-price and /api/btc-price
additionally carry an MPP solana/charge challenge. All of them ride the same response, so
a client settles with whichever protocol it speaks. The two live in disjoint header namespaces, so an x402-only client never sees the MPP
one and is unaffected.
Base64-decoded, that MPP request is the whole quote:
Note what is not there: no feePayer. The client pays its own transaction fee and the
server holds no funded signing key, which is the difference between the MPP challenge and the
Solana x402 one sitting beside it in the same response.
Replay is refused, not merely discouraged. A settled signature is claimed atomically in SQLite before the resource is served, so two processes racing the same credential produce exactly one 200 and one refusal — covered by tests that fork real worker processes rather than stubbing the race.
The layer is fail-soft by design. If it cannot initialise it logs [mpp] DISABLED: <cause>
and the service keeps serving x402 on every route rather than taking the paid surface down
with it. Which routes are gated is published live at / and in /.well-known/x402.json under
mpp.routes, so the advertised set is always whatever is actually mounted.
AgentFeed is one of several merchants accepting MPP on Solana mainnet — the Foundation's own
Google proxy and smartmoney-market in solana-foundation/pay-skills do too.
The pay-kit fix ships here as mpp/patches/@solana+mpp+0.7.0.patch, applied by
patch-package on install and asserted by npm run verify-patch — the patch is a production
dependency, not a dev one, because a --omit=dev install would otherwise complete silently
unpatched.
A bot that calls often pays half the route's price, minimum $0.0005, through either of two schemes that ride the same 402 as the per-call accepts. Per-call prices do not change. The six prepaid-key purchase routes carry per-call accepts only. The Gateway accept is offered on Arc only: it was withdrawn from Base, Polygon and Arbitrum on 18 Oct 2026, because buyers whose client picked it as the cheapest accept of the chain signed a plain USDC authorization to the Gateway wallet, which is not a Gateway payment and was refused.
A call that answers 400 or more is never charged on either scheme.
Twelve routes take their argument as the last path segment: /api/wallet-activity/{wallet}, /api/token-risk/{mint}, /api/coin-signal/{coin},
/api/sanctions-check/{address}, /api/domain/{domain}, /api/paper/{doi} and the other six. In this README, in llms.txt and in
openapi.json, {wallet} marks the part you replace; it is not a URL. Every URL the service publishes for a caller to GET is a working example
instead: /.well-known/x402.json lists
https://x402.ochinimus.app/api/wallet-activity/Gack9UtqfeZxFA1LqeqjLgC3JGuD7rS6CsSHKoXsD4Tu as the resource and the {wallet} form as
resource_template; openapi.json gives each path parameter an example and the pattern, minLength and maxLength it must satisfy; the 402's Bazaar
declaration carries the same schema. The DOI example is published as one segment, /api/paper/10.1038%2Fnature14539 (the URL CDP's index already holds for this route); the
slash spelling /api/paper/10.1038/nature14539 is still served. CDP's /validate fails this one route on bazaar.routeTemplate.matches_resource with either spelling (it
behaves as if it decodes the path before splitting it, and a DOI always contains a slash); the other 90 priced routes validate. The existing ?doi= alias fails it too (measured: its 402 still names the template /api/paper/:doi); only a priced route whose template has no DOI in the path would pass, which is a route redesign and an open decision.
Trade-off, decided 29 Oct 2026: the catalogue lists these concrete example URLs, not the {wallet} templates. A directory that keys its listing on the URL
(Agent402 does) may therefore show a route twice, once from the catalogue and once from the 402's own route template. That is cosmetic. A listed URL that answers
400 is broken, which is what the literal templates were. To go back, change the concrete line in buildWellKnown (tools/discovery.js).
A value that can never be served is refused before the paywall. GET /api/wallet-activity/:wallet and GET /api/wallet-activity/notawallet answer
400 with the reason, the shape expected, a working example URL and "charged": false: no 402, no challenge, no prepaid-key reserve, nothing sent to a
facilitator (lib/param-guard.js, before every payment layer). The check is shape only and uses the validator the handler itself uses: a Solana wallet or
mint is 32 to 44 base58 characters, a coin 1 to 20 letters or digits, an address 14 to 120 letters and digits, a domain a public hostname, a DOI
10.xxxx/.... Whether the address has an account, the coin is listed or the DOI exists is still answered after payment, and a call that then answers 400 or
more is never settled on any rail (test/param-guard-real-server.test.js). Over MCP the same patterns are in each tool's input schema, so an impossible
argument is rejected before the payment prompt. MPP solana/charge settles on chain before the handler runs, so it is offered only on the two routes that take
no input (/api/sol-price, /api/btc-price); MPP tempo/charge and every x402 scheme settle after it.
The same guard covers the values of query parameters that a route's handler would refuse with a 400 anyway: an integer outside its range
(/api/sol-token-flow/{mint}?swaps=5 needs 20 to 100), a word outside its list (?alg=md5, ?format=jpeg, ?length=long, ?class=bonds), a code of the wrong
shape (?base=EURO, ?lang=english, a 0x address that is not 40 hex digits), a url= that is not an absolute http or https URL (?url=example.com), a text or
data over the route's length cap (4,000 characters; 2,048 bytes), a schema= that is not the JSON object the route needs. Such a request answers 400 with error, param, expected, received,
a working example URL and "charged": false, before any 402 (lib/query-rules.js, mounted by lib/param-guard.js). The rules copy the handler's own checks and
read a value the way the handler does (Number() on the raw text, words lower-cased, an empty value is "not given"); test/query-guard-real-server.test.js runs the real
server twice, with the rules on and off, and requires that every value the guard refuses is refused by the handler with the same sentence. Not guarded, on purpose:
a missing parameter (the query-less URL of each route is the one every catalogue lists, and it stays a 402), symbols and tickers that need an upstream to be judged
(Hyperliquid's universe, the SEC list), URLs and free text, and limits the handler clamps instead of refusing (limit on /api/liquidations, window on
/api/cascade, and others). 52 rules on 30 routes today; the full list is lib/query-rules.js. The integer and number ranges are also in each MCP tool's input schema and in the minimum / maximum of openapi.json and of
the Bazaar declaration. AF_QUERY_GUARD=off in the environment (restart) switches the query rules off and leaves the path rules on.
X402_ALGO=off is set on the live box. CDP's Bazaar validator (POST https://api.cdp.coinbase.com/platform/v2/x402/validate) parses every accept of a route, and a network id
outside the CAIP-2 grammar (namespace:reference, the reference 1 to 32 characters of [-_a-zA-Z0-9]) fails its required check parse; the whole route is then
rejected: invalid discovery configuration (measured on all 91 priced routes). The Algorand id that the GoPlausible facilitator publishes,
algorand:wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8=, is 44 characters with a trailing =. With the rail off 90 of the 91 routes validate (valid: true, simulation accepted, 25
of 25 checks pass); the 91st, /api/paper/{doi}, fails only bazaar.routeTemplate.matches_resource (see "Path parameters"). No payment was ever made on Algorand. The code stays (lib/rails.js); to offer the rail again, remove the line and restart, once CDP accepts the id
or the facilitator publishes a CAIP-2 one. test/caip2-networks.test.js fails if any other network id leaves the grammar.
Keep the pay object alive between calls. A client that starts a fresh process for every call is asked once to resync while vouchers are outstanding, and is then served in the same request.
Full script, with a guard that checks the accept before anything is signed: ops/proof-batch.mjs.
The Gateway accept is on Arc only (see "Pay on Arc" below for the full walk-through): ops/proof-gateway.mjs (CHAIN=arc, the default) deposits into the GatewayWallet once and pays one nanopayment.
All of them were paid from our own test wallets.
Every paid route takes USDC on Arc mainnet (eip155:5042, USDC 0x3600000000000000000000000000000000000000, 6 decimals) in two ways. Both sit in the same 402 as the other rails (the prepaid-key purchase routes offer the exact one only), so a client pays with whatever it holds. Gas on Arc is paid in USDC, so a buyer needs nothing else.

Ask for one by suffixing the route: GET /api/<route>|<network> (the | may be sent as %7C), for example /api/sol-price|eip155:42220 for Celo. The 402 that comes back carries the default accepts plus that network's accept, and a payment on any network is accepted on the plain URL too. The prepaid-key purchase routes carry the eight only. The first five networks (Solana, Base, Polygon, Arbitrum, Arc) are described under "Two payment protocols on one 402" and "Pay on Arc"; the table lists the other fourteen, generated from lib/ext-rails.js. Every row is scheme: exact (EIP-3009), paid to the same EVM treasury, settled by the one facilitator named in the row.
The token is not USDC everywhere: BNB Chain settles AUSD, Robinhood Chain USDG and SKALE Base USDC.e. Sei and X Layer are offered only on routes priced $0.005 or more, because PayAI charges per settlement.
@x402/fetch 2.28 refuses any token outside @x402/evm's DEFAULT_ASSETS unless the client opts in with spendControls.allowedAssets. Out of the box a stock client pays Monad, Avalanche, Celo, Ethereum and Sei. It is refused on Optimism, HyperEVM, Unichain, Scroll, SKALE Base, BNB Chain, Robinhood Chain, World Chain and X Layer until the token is allowed. The option shape, from @x402/core's own type definitions:
A payment on Optimism, with the token allowed explicitly (the cap '50000' is $0.05; the token is the address in the table):
Without the spendControls line the same client throws "All payment requirements were rejected by spendControls". Full script, with a dry run that prints the accept before anything is signed: ops/r10-proof-evm.mjs.
/api/sol-price|<network>, each one USDC transfer from our test wallet to the treasury: Optimism 0xdc64…d4c5, Monad 0xdf06…da2d, Avalanche 0x5c3e…70d0.All of them were paid from our own test wallets.
95 paid + 7 free, 102 total on the MCP rail (the eight prepaid-key routes below are HTTP only). Every call is metered individually in USDC over x402 — no bundles, no minimums. Calling all 95 paid data tools once costs $3.267. Counts and prices are summed from the live manifest, read 2026-11-01.
The flagship is get_squeeze_score — a 0-100 short-squeeze / long-flush composite built from funding, crowding, OI build and the liq-skew of our exclusive tape. One number, one dime, answers "is this trade crowded and about to hurt someone."
Short composed answers built only from data AgentFeed already collects. Each one gives the judgment (what changed, why it matters, the one level to watch) rather than a raw number; the text is templates filled from the numbers, with no language model, and every item names its sources and their age. No path or query parameter. A part that is stale is left out and named in stale_parts; when the core of a brief cannot be built the route answers 503 and is never billed. They are also open to a 30-day brief pass and a 24-hour brief day pass (/keys). Prices can change; the live 402 challenge is authoritative.
Sampled every 5 minutes. Deviation is measured against the underlying's last real trade — outside US market hours that is the last print before the close, not a live quote. Dead pools are excluded rather than reported as perfect pegs.
| get_honeypot_check | $0.01 | /api/honeypot-check | Use when an agent needs to know whether a token on Base, BNB Chain or Ethereum can be sold before it buys. Returns a verdict from our own buy-then-sell simulation on the token's deepest pool, with the buy and sell tax measured. Also: whether a wallet transfer works, bytecode flags (mintable, blacklist, proxy, pausable, owner), where simulation and bytecode disagree, and the block. Uniswap, Aerodrome and PancakeSwap pools. No pool found is a finding; RPC failure answers 503. |
| get_base_launches | $0.02 | /api/base-launches | Use when an agent needs the newest token launches on Base. Returns pools created on Base in the last 24 hours on Uniswap V4, V3, V2 and Aerodrome, newest first, with launchpad, liquidity and volume. Each carries its pair, creation time, launchpad named from the V4 hook (Zora, Clanker, Doppler, Flaunch), quote-side liquidity, 24h volume and swaps, and our honeypot simulation for the busiest. Read from Base logs every minute; a snapshot older than 5 minutes answers 503. |
Sources and their terms: the OFAC SDN list (a US federal government work), the CC0 disposable-email-domains list, DNS and a live TLS handshake, OpenAlex (CC0 data), Wikipedia (CC BY-SA 4.0, attribution in every answer); details in docs/SOURCES.md.
Four routes that check something before an agent acts on it. A package version with a published advisory, a transaction before it is signed (simulated with our own RPC; nothing is ever signed or sent), a US-listed company from its SEC filings, and the yield tokenized treasury and credit products have actually realized, computed from the price each issuer's contract publishes. Each one says which source it read; every failure that is not the caller's is a 503 or 404 that is not charged. Sources and terms in docs/SOURCES.md.
Five routes that look outward: two read the payment challenge of an x402 endpoint you name (one of them also makes a single real payment to it from a dedicated wallet), one checks a claim against filings, Wikipedia and pages you give it, one reads the public signals of a website, one measures what price did after past liquidation cascades on our tape. Every URL you give is fetched only through one guard (private, loopback and metadata addresses refused after DNS, 3 redirects, 5 MB, 10 s). A route that cannot answer returns 503 or 404 with "Not charged" and settles nothing; get_x402_test answers that way while its wallet is unfunded.
Sources and their terms: the caller's own endpoint or site, SEC EDGAR filings, Wikipedia (CC BY-SA 4.0, licence named in every answer), Hyperliquid 15-minute candles, our own liquidation tape (sums and counts only), DNS and a live TLS handshake; what was left out for data-terms reasons, and why, is in docs/SOURCES.md.
Each one is a single fixed task on Google's Gemini API (paid tier): the caller supplies content, never a prompt, model or setting. Untrusted content travels as delimited data, every output is schema-checked, and a provider failure is a 503 that is never billed. These seven are available only to callers inside Google's available regions: elsewhere they answer 451 before any payment.
Both read only data this service records itself (the Hyperliquid OI sampler, the liquidation tape, the whale snapshot) and name every source with its as_of; a stale source answers 503 and is never billed. With a prepaid key they cost $0.005 and $0.002.
GET /api/liq-feed is cross-venue liquidation pressure, computed by AgentFeed from its own liquidation recording and served the way a bot polls: 5-second buckets, a cursor that never skips and never repeats, and a floor price.
longs and shorts (USD, base quantity and VWAP of the long and the short positions liquidated, all venues combined into one figure), dominant (longs, shorts or balanced: the side holding at least 60% of the bucket) and pressure (the bucket's USD against the symbol's own typical USD per 5 seconds, its median hour of the last 7 days floored at $5,000 an hour). Numbers are rounded to 2 significant figures (3 for the VWAP) and no count of prints is returned.since=<ms> once (up to 24 h back; without it the first call begins 2 minutes back), then send each answer's next back unchanged. A bucket is served only after it has been closed for 10 seconds, every closed bucket is served exactly once, and has_more tells you to ask again at once. Up to 20 symbols and 500 rows a call (symbols=BTC,ETH,SOL, or BTC-USDT style).Retry-After, never billed; a call that follows an answer saying has_more is exempt). A key has the same single clock over REST and over the MCP tool get_liq_feed; an x402 payer is keyed by IP over REST and by paying wallet over MCP. The horizon moves in 5-second steps, so a call sooner than that could not carry a new bucket. At the 5-second floor that is 17,280 calls and $8.64 a day on a key; at a 30-second poll 2,880 calls and $1.44 a day; at 60 seconds, $0.72. A bot pass ($25 flat for 30 days, this route only) is $0.83 a day at any poll rate.Seven, of which four have an HTTP route — those four are the ones published at / under
free_tools. The other three are MCP-only and have no paid HTTP equivalent to undercut.
Two more free HTTP endpoints carry no tool of their own:
A free route answers "paid": false, and a paid one "paid": true, because that field is
per-request: it reports whether the route you called is priced. curling either of the two
above costs nothing and says so.
Set AGENTFEED_PRIVATE_KEY to a funded Solana wallet and the agent pays per call automatically. Default spend cap $0.50/call (AGENTFEED_MAX_SPEND_PER_CALL to change).
x402 clients pay and retry automatically.
A bot that can set an HTTP header but cannot sign an x402 payment (n8n, Freqtrade, Hummingbot, a plain script, a gateway such as claw402) buys a key once and spends it per call.
GET /api/keys/buy-trial ($0.25), buy-1, buy-5, buy-20. Top up with topup-5 or topup-20, sending the key as the header. Or in a browser at /keys with a Base wallet: the page loads no library and sends nothing but the key's hash.X-AgentFeed-Key: afk_... (or Authorization: Bearer afk_...) on any paid GET or on POST /mcp. Each call draws half the route's x402 price, minimum $0.0005, from the balance; a 400, 404, 500 or 503 is never drawn. 120 requests per minute per key.afk_ + base58 of 32 random bytes yourself and buy with ?key_hash=<sha256 hex>&prefix=<8 characters after afk_>; the server registers the hash and never sees the key, and a dropped connection after payment loses nothing. Without key_hash the server generates the key and returns it once.GET /api/keys/buy-pass ($25) is a different kind of key for a bot that polls /api/liq-feed all day: valid for 30 days from the moment its payment settles, good only on /api/liq-feed (and the MCP tool get_liq_feed), nothing drawn per call, still one call per 10 seconds. Every other route answers 403 to it, it cannot be topped up, and GET /api/keys/balance shows its routes and expiry. At a 30-second poll it costs $0.83 a day, against $1.44 a day on an ordinary key.GET /api/keys/buy-day-pass is $1.00 flat for 24 hours from the moment its payment settles, good only on /api/liq-feed and /api/liquidations, nothing drawn per call, each of the two routes one call every 10 seconds per key (6 a minute; a call inside the 10 seconds is a 429 with Retry-After, never billed). It is the pass a default x402 client can buy as it is: @x402/fetch 2.28 refuses any payment over $1 before signing and accepts exactly $1.00 (measured), so the $5 and $20 packs and the $25 bot pass need spendControls raised and this one does not. Every other route answers 403 to it, it cannot be topped up, and GET /api/keys/balance shows its routes, expiry and hours left. Also in the browser at /keys.GET /api/keys/buy-signals-pass ($25) is one flat key for the briefs and the perp signal routes, valid for 30 days from the moment its payment settles, and GET /api/keys/buy-signals-day-pass is $1.00 flat for 24 hours: good only on /api/morning-brief, /api/move-alert, /api/anomaly-flag, /api/market-state, /api/signal-board, /api/coin-signal/:coin, /api/oi-spike-scan, /api/liq-heatmap (and their MCP tools), nothing drawn per call, each route one call every 60 seconds per key (a call inside that is a 429 with Retry-After, never billed; /api/coin-signal/:coin keeps one clock for every coin, so read several coins at once with /api/signal-board?coins=BTC,ETH,SOL). For an agent that runs on a schedule with nobody to approve a payment: the key goes in X-AgentFeed-Key from an environment variable. Every other route answers 403 and names the covered ones, an expired pass 401. Non-refundable, no top-up, a bearer secret; the stock x402 client's $1 spend cap buys the day pass as is.GET /api/keys/balance with the header, free.paid); the calls it funds are rows of status key, consumption of credit already counted, never revenue.Five AgentFeed data sets are also Apify Store actors. The Store bills in fiat through Apify, so no wallet is needed.
Prices are per result, plus Apify's $0.00005 start fee per run.
NOFX is an open-source AI trading terminal. get_signal_board and get_coin_signal are shaped for its External Data Sources: data.coins is an object keyed by coin in open-interest order, data.ranked is the list, data.sources names each source, and the board is about 10 KB for 30 coins. Read this first: at NOFX commit ef476f2 nothing calls the function that fetches External Data Sources (StrategyEngine.FetchExternalData), so stock NOFX saves the two entries and never reads them into a prompt; they work on a NOFX build that calls it, and the same key works from anything else that sends a header. docs/nofx.md (中文) has the exact strategy JSON, how to buy a key from the wallet NOFX already pays claw402 with, the cost per trader (about $0.48 a day for the board and $0.19 a day per coin at NOFX's default 15-minute scan) and the proof harness that replays NOFX's fetch and data_path walk against the live routes.

2026-07-31 a lookalike of the Base treasury (same first and last characters as
0x22DB…76e6) sent zero-value address-poisoning transfers to our biggest buyer, so a
wallet's history can show a fake payee next to the real one.
test-client.mjs is the repo's own Solana x402 payer: @x402/svm's ExactSvmScheme behind
wrapFetchWithPaymentFromConfig, reading a standard solana-keygen 64-byte JSON keypair.
test-client-evm.mjs is the same thing over Base (eip155:8453) with a viem account, and
test-mcp-client.mjs pays MCP tool calls over Streamable HTTP. Settlements land in the audit

pay CLITwo MPP payments settled against this service on 2026-09-19, at 21:53:39 and 21:57:36 UTC, and both signatures are recorded in the replay store so neither can be spent twice.
The pay CLI needs an interactive session. An account with auth_required: true blocks on
a Touch ID prompt that cannot render in CI, a headless agent or a scheduled task, and it blocks
without a timeout — it looks exactly like a network hang while holding zero TCP sockets. That
is solana-foundation/pay #469. Run it
from a real GUI session, or use an account without auth_required.
Point any MCP client at https://x402.ochinimus.app/mcp (Streamable HTTP, POST). Paid tools
return payment terms; an x402-capable client settles and retries.
createx402MCPClient is exported by the published @x402/mcp (checked against
the npm tarball, 2.27.0, 2026-09-23). This is what test-mcp-client.mjs in this
repo actually does:
Also available as an elizaOS plugin.
Every variable the service reads, derived from the source
(grep -rhoE "process\.env\.[A-Z0-9_]+"). Only HELIUS_API_KEY, PAY_TO and — when MPP is
on — MPP_SECRET_KEY have no working default.
DB_PATH, SIGNATURE, VERIFY_DELAY_MS, HOME and PATH appear only in the MPP test
harness (mpp/test/helpers/) and are not service configuration.
Neither package.json declares a test script; the commands above are the ones the test
files themselves document.
test/tool.test.js mounts the real wrapper from lib/tool.js — the same module server.js
mounts, not a copy — on a throwaway express app over a real socket, so req.route is
populated exactly as in production. It covers a priced route, a path-parameter route (which
is what proves the flag matches on the registered pattern and not the request URL), an
unpriced route that is nonetheless registered with a price argument, X402_MODE=off, the
audit row's field set on success / error / bad_request, and prototype pollution through
req.route.path.
Two of the MPP tests fork real worker processes to race the replay store across process boundaries rather than simulating the race in one event loop.

Liquidation pulse
Use when an agent needs to know what is being liquidated right now. Returns the last 60 minutes across every USDT perp we record: total USD, long/short split, prints and the top 5 symbols. If our recording is stale it answers 503 and is never billed. Costs 0.005 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Perp snapshot
Use when an agent needs one perp market in a single call. Returns Hyperliquid funding and open interest (with 1h/24h change from our 5-minute sampler) and 24h liquidations with long/short split and biggest print from our own tape. A symbol nothing lists answers 400 and a failed read answers 503; neither is ever billed. Costs 0.005 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
symbolFunding pulse
Use when an agent needs the most extreme funding rates right now. Returns the 5 largest absolute annualised rates across the Hyperliquid perps above a liquidity floor, each with 8h rate, open interest and 24h price move. One call, not a full screen. Costs 0.005 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Liquidation leaderboard
What is blowing up RIGHT NOW: top symbols ranked by liquidation USD across every USDT perp we record on Bybit, OKX and Binance. Per symbol: total liquidated, long vs short split, biggest single print, venue count, dominant side. The fastest read on where leverage is being flushed. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
limitwindow_minFull universe cascade scan
Liquidation cascade scan across EVERY USDT perp we record at once, not just the majors: symbol, side liquidated, USD total, prints, duration, severity. Computed from our own multi-venue liquidation tape. Costs 0.05 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
windowmin_usdmin_eventsLiquidation heatmap
Liquidation heatmap by PRICE LEVEL: where leverage actually got flushed in the last N hours — USD, prints and long/short split per price zone, with the hottest zone flagged. Built from real liquidation prints, not entry-price estimates. BTC, ETH, SOL, HYPE or any other USDT perp on our multi-venue liquidation tape. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
hourssymbolbucketsSqueeze score
Short squeeze score and long flush score, 0-100, for any Hyperliquid perp. Composite of Hyperliquid funding (35), whale crowding (25: the net-long share of the top 250 Hyperliquid accounts in the coin, not retail), the 24h open-interest build from our own 5-minute sampler (20) and liquidation skew from our own tape (20). One number for whether a trade is crowded and about to hurt someone. A symbol nothing lists answers 400; while the open-interest record is under 24 hours deep, or Hyperliquid or the whale snapshot is unavailable, it answers 503; both are never billed. A listed coin none of the top 250 accounts holds returns 200 with a decline naming the missing input. Costs 0.1 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Forecast track record
FREE: the live track record of this miner. Every forecast was written down BEFORE its 15-minute window opened and settled afterwards from the exchange public feed, and the raw rows are returned alongside the score so you can recompute it yourself rather than take it on trust. Returns settled count, base rate, Brier skill against climatology, coverage, calibration error and a reliability curve. A backtest is a claim about the past that its author also chose how to compute; this is not that. Free.
rowssymbolLiquidation cascade forecast
Liquidation forecast, FORWARD-LOOKING and not a description of what already happened. Returns the probability that a symbol will liquidate more in the NEXT 15 minutes than its own 90th-percentile 15-minute window. Calibrated on our whole multi-venue liquidation tape, over 6 million liquidations, refit every 6 hours; no exchange publishes that history, so it cannot be rebuilt. Every answer carries the exact question, the threshold in USD, the window it read, the number of historical occurrences behind the number, and instructions for settling it yourself from the public feed. When a state has too little history the tool DECLINES rather than guessing, and says why. The settled record is free at /api/forecast-record. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

FREE: how overhang measures exit liquidity on lending collateral, and the counts behind every paid answer - computed from the tape at request time, nothing hardcoded. Returns what is measured (the protocol's own live-refetched mark vs realisable value from sell-direction quotes at real clip sizes), the corroboration rule in plain terms (a terminal verdict needs six consecutive agreeing floor observations from the symbol's own tape; one sample is never enough; a contradicted floor buys a fresh probe rather than writing a hole), the full status vocabulary including why a router refusal and an empty book are different facts, the size-matched control design and its results, the gated sweep and row counts, covered symbols and markets, and the measured cadence. Read this before paying for get_exit_quote, and to check the claim rather than trust it. Free.

limitmin_turnover_usdFunding radar
Funding radar over every Hyperliquid perp: 337 on 13 Oct 2026, 178 on the main dex and 159 on the HIP-3 dexes (stocks, indices, commodities, FX). Per perp: the current funding at its 8h equivalent, its 30-day z-score against its own settled history, the dex and asset class, and a flag on any |z| of 2 or more, most extreme first. By default it returns the perps with $10M and up of open interest; min_oi_usd changes that and 0 returns them all. Precomputed every 5 minutes with as_of; a snapshot older than 15 minutes answers 503 and is never billed. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Market state for BTC, ETH, SOL or HYPE in one call: spot and the perp's basis against the Hyperliquid oracle, realized vol 7d and 30d, funding with its 30-day z-score, open interest and its changes, the top Hyperliquid accounts' net-long share, liquidations 1h and 24h by side, Fear and Greed, the next FOMC or CPI release, and flags with stated thresholds. Every part carries its source and as-of time; a part we do not hold is null with a reason. When nothing of the market itself could be built it answers 503 and is never billed.

Indicative, never an exchange quote; 503 when no source has liquidity. Costs 0.01 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
symbol必填Open interest spikes
Open interest spikes across every Hyperliquid perp: coins whose open interest moved abnormally in the last hour against their own previous day, with the 1h, 4h and 24h change (in coin units, so a price move does not count), a spike z-score, the price move and funding. Read from our own 5-minute sampler: it answers 503 and is never billed until that record is 24 hours deep. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Tokenized stock peg
Tokenized stock peg deviation on Solana: the on-chain DEX price of a tokenized US equity versus the underlying's last real trade, in bps, with 24h stats split into market-open and off-hours. Sampled every 5 minutes by our own collector; the token price is read on-chain. latest.reference is null: the underlying's reference price is not returned (its source does not allow redistribution), only the deviation computed from it. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
hourssymbol必填Peg by session
Tokenized stock peg by trading session: deviation broken out across open, premarket, afterhours, overnight and weekend — mean, p95, max bps and median liquidity each, with the worst off-hours window flagged. Market-open acts as the control. Costs 0.03 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Dead pools are excluded rather than reported as perfect pegs. Costs 0.05 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
daysmin_liquidity_usdCollateral exit liquidity
EXIT LIQUIDITY on seized collateral: what a liquidator ACTUALLY realises selling a Kamino reserve into live routing, versus the oracle price the protocol marks it at. Returns max_exitable_usd (largest clip whose liquidator margin is still positive, found by bisection, with its resolution width), the exitable fraction, the conservative bound at the 2% penalty floor, and for the nearest clip actually probed: realised USD, haircut bps and liquidator margin bps. Distinguishes a router that REFUSES to quote a token (permissioning, not illiquidity) from a book with no route (a real liquidity finding) - they are different facts and were one status until this split. A terminal verdict requires six consecutive agreeing observations from the symbol's own tape, so a single bad quote cannot produce a finding; withheld verdicts fall back to the last corroborated measurement with its age rather than returning null. Zero bad debt today does not disprove any of this - it means nobody has been forced to test it at size. Method, corroboration rules and row counts are free via get_exit_method. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Base gas price
Base gas price (chain 8453) in BOTH gwei and wei, with base fee, priority fee and block number when the node supplies them. Both units are returned because a caller asking in wei and a caller asking in gwei are asking the same question. Served from keyless public RPC with three-node fallback, so there is no API key to rotate or expire. Costs 0.005 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
無需輸入參數。
Base wallet balance
ERC20 and native ETH wallet balance on Base or Ethereum mainnet, for a 0x address or an ENS name. decimals() and symbol() are read from the contract at request time rather than assumed, because assuming 18 reports a USDC balance a trillion times too large. ENS is resolved through two independent resolvers and the answer is used only when they agree, so a wrong address can never produce a confident balance for the wrong wallet. An unsupported chain is refused rather than silently answered from the wrong one. Costs 0.005 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
chaintokenaddress必填Honeypot check
Use when an agent needs to know whether a token on Base, BNB Chain or Ethereum can be sold before it buys.

Also: whether a wallet transfer works, bytecode flags (mintable, blacklist, proxy, pausable, owner), where simulation and bytecode disagree, and the block. Uniswap, Aerodrome and PancakeSwap pools. No pool found is a finding; RPC failure answers 503. Costs 0.01 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
chaintoken必填Base launches
Use when an agent needs the newest token launches on Base. Returns pools created on Base in the last 24 hours on Uniswap V4, V3, V2 and Aerodrome, newest first, with launchpad, liquidity and volume. Each carries its pair, creation time, launchpad named from the V4 hook (Zora, Clanker, Doppler, Flaunch), quote-side liquidity, 24h volume and swaps, and our honeypot simulation for the busiest. Read from Base logs every minute; a snapshot older than 5 minutes answers 503. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
limitmin_liq_usdHyperliquid whales
Use when an agent needs to know how the biggest Hyperliquid traders are positioned. Returns the open perp positions of the largest Hyperliquid accounts aggregated per coin: net long or short USD, account counts, size-weighted entries, notional-weighted distance to liquidation, notional within 10% of liquidation and uPnL. With coin=BTC: whale liquidation levels in 5% price bands and the largest positions. Refreshed every 5 minutes; stale data answers 503. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
topcoinWeb page to markdown
Use when an agent needs the readable text of a web page as markdown. Returns the main content of the one URL you pass as clean markdown (Mozilla Readability, then turndown), with title, final URL, fetch time and word count. http or https on ports 80 and 443, 5 MB, 10 s; robots.txt honoured and private addresses refused. A blocked or unreachable URL is never charged. Costs 0.005 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Use when an agent needs the text of a PDF as markdown. Returns the text of the one PDF URL you pass, page by page as markdown, with title, page count and word count. http or https, 10 MB, 10 s; robots.txt honoured and private addresses refused. A file that is not a PDF, a PDF with no text layer (a scan), or an unreachable URL, is never charged. Costs 0.01 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Use when an agent needs a US company's latest SEC filings. Returns the most recent EDGAR filings for a ticker, optionally one form type (10-K, 10-Q, 8-K, 4, S-1, 13F-HR), with filing date, report date, accession number, description, 8-K item codes and links to the document and the filing index. Source: SEC EDGAR public filings. Costs 0.005 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
formlimitticker必填Insider trades
