APEX Faucet

Call this before sending USDC on Arc or Base. One EIP-712 PaySafeVerdict (domain APEX PaySafe, version 1, chainId 5042) covers the payee (Arc poison index, lookalikes, USDC blacklist, OFAC SDN file; Base is the USDC blacklist only and a missing lookalike index is CAUTION), a duplicate of resource+payee+amount+nonce when all three are present, our catalog price, and whether that endpoint has a prior delivered settlement. Verdicts: PASS, CAUTION, DO_NOT_PAY, COULD_NOT_READ. PASS needs every code clean. A missing nonce is CAUTION, not a stop. PayGuard does not read this type. This is not a permission to pay. 20 free a day at /pay-safe, then $0.01. Up to 10 for $0.03 (pass items). 100 prepaid checks for $0.20 are call units, not a USDC balance: pass credit. Hook: /pay-safe/apex-pay-safe.js (onBeforePaymentCreation). It stops only on DO_NOT_PAY, COULD_NOT_READ and a used-up free day. tier=lite is a separate $0.002 call at /api/x402/pay-safe-lite: payee check only. It does not run the duplicate, catalog price or delivery checks, it does not return PASS, and it does not use the free day or a credit. Drop-in examples for Syncly, Vestiarion, Mercenta, Elpis and Circle Gateway: https://apexfaucet.xyz/x402-clients/. Arc builders, including Tameion: https://apexfaucet.xyz/arc-builders/. 20 free full checks a day, then $0.01. Lite stays $0.002.

Call this before any USDC send on Arc. We index every Arc USDC transfer: in the 7 days to 3 Nov 2026 there were 134 address-poisoning events from 50 lookalike addresses against 105 wallets (live counts: arc_poison_stats). Returns an EIP-712 signed verdict: DO_NOT_PAY / CAUTION / NO_MATCH_IN_INDEX / COULD_NOT_READ, with the address it imitates and evidence transactions; also the USDC blacklist and OFAC. 5 free checks a day per caller (no payment needed), then $0.005 over x402. Use it with PayGuard (0x942e886e4aa48346dd8bc594596f662aab57efeb on Arc) so the contract only pays on a clean, fresh verdict: pass payer and amount for that. When the verdict is NO_MATCH_IN_INDEX, that signature is an apex-upto-v1 voucher (a cap, 10 minutes, once). New boxes (arc-mandate-2, factory 0x91957bd6e6da2880bf49174eaa4b5d36627af9d3) pay only on a clean PayeeVerdict whose payer is the box. pay() uses a verdict once. x402 can reuse one unexpired verdict on each free daily slot, and the daily count still applies. Boxes from the v1 factory 0x69e444f722666e13e171181efe054a93e0976b26 do not read the verdict. The v2 factory and the v2 implementation are Sourcify exact matches. Up to 20 payees: arc_payee_batch. arc-send-guard folds the same check: DO_NOT_PAY is a stop, and the signed verdict is arc-payee-check. Our own payouts to an address a stranger chose (the X reward, jury pay, the hunter bounty, and buy-and-rate) refuse DO_NOT_PAY before USDC leaves. A first payment to a new address is still allowed.

Check up to 20 Arc addresses before paying USDC ($0.02 for the batch, or the shared 5 free checks a day, one per payee). Each address gets its own EIP-712 PayeeVerdict. A voucher (scheme apex-upto-v1) is present only when the verdict is NO_MATCH_IN_INDEX, you passed payer and amount (at least 0.01 USDC): that signature caps the payment until it expires, and PayGuard pays it once. New boxes (arc-mandate-2, factory 0x91957bd6e6da2880bf49174eaa4b5d36627af9d3) pay only on a clean PayeeVerdict whose payer is the box. pay() uses a verdict once. x402 can reuse one unexpired verdict on each free daily slot, and the daily count still applies. Boxes from the v1 factory 0x69e444f722666e13e171181efe054a93e0976b26 do not read the verdict. The v2 factory and the v2 implementation are Sourcify exact matches. DO_NOT_PAY, CAUTION and COULD_NOT_READ include no pay call. Policy: https://apexfaucet.xyz/.well-known/apex-trust.json

Before you pay the same x402 request again: flags a repeat of resource + payee + amount + nonce inside a time window (default 600 seconds, clamped from 60 to 86400). EIP-712 signed (domain APEX DuplicateGuard, type DuplicateVerdict) by the payee attester. Verdicts: FRESH, DUPLICATE, COULD_NOT_RECORD. This is not a permission to pay, and PayGuard does not read this signature. One check is $0.003 after 5 free a day; up to 20 is $0.01 (pass items). A batch of 21 is refused and nothing is recorded. Free doors: /check/duplicate and /check/duplicate/batch. The official client hook runs before the EIP-3009 nonce exists, so pass the nonce you will sign. Live poisoning counts stay on arc_poison_stats.

Before USDC moves on Arc: one call runs the payee check and, when you pass resource, nonce and amount together, the duplicate check. Summary is DO_NOT_PAY, DUPLICATE, COULD_NOT_READ, CAUTION or NO_MATCH_IN_INDEX. The signatures are the existing PayeeVerdict and DuplicateVerdict. There is no new domain. A FRESH verdict only means that fingerprint was not seen inside the window. NO_MATCH_IN_INDEX means nothing in the Arc index pointed against this payee. An amount under 0.01 USDC is CAUTION on the payee half. This is not a permission to pay. Five free a day at /pay-preflight, then $0.01. Live counts stay on arc_poison_stats.

Render any public web page in a real headless Chrome and return its text. JavaScript runs first, so docs sites and single-page apps that a plain fetch returns empty come back complete. $0.009 per call (x402 on Arc/Base/Solana/X1): the full text and every outbound link. Without a payment the call returns the price and every rail we accept. Refuses private and reserved addresses and our own hosts, so it cannot be used as a proxy into a network. Sites that put a bot wall in front of their pages (Cloudflare, DataDome and the like) answer with a challenge rather than the page: the call then FAILS with `http-403` or `bot-challenge` and says so, rather than charging you for a spinner.

Render a whole section of a site - up to 25 pages - in one call and get every page back as clean text, with JavaScript executed. Same host only; robots.txt is obeyed and anything it disallows is skipped and named. FREE: the crawl PLAN - exactly which pages would be fetched and what robots.txt allows - so you can see what you would get before paying. PAID ($0.14, x402 on Arc/Base/Solana/X1): every page rendered and returned. It costs more than one page because it is up to 25 real browser renders, not a lookup. If a bot wall on the site lets the first page through but blocks the rest, the call fails with `poor-yield` and names every page it could not render, instead of billing you for a list of failures.

How to get onto the X1 chain and fund a wallet with APEX/XNT from outside — bridge from Solana (USDC or SOL), or claim free tokens from the faucet. Returns the real bridge deposit address, limits and endpoints. Start here if you have no X1 balance.

SEVEN CHAINS, FROM LIVE RESERVES OR AN AGGREGATOR QUOTE (for an executed sell test use arc_exit_check on Arc or base_exit_check on Base). Before you buy a token, find out whether you can sell it. Give a token address and a position size in USD and this returns what you would actually receive, the slippage, and the largest position that exits under 5%. WORKS ON SEVEN CHAINS: Solana and X1 (base58 address, constant-product maths against the pool's live reserves and its own fee) and five EVM chains (0x address, routed through LI.FI to USDC) - Base 8453 (the default), Ethereum 1, Arbitrum 42161, Optimism 10, Polygon 137. Any other chain id returns UNSUPPORTED_CHAIN and names these five; it is never reported as a token you cannot sell. This is deliberately NOT a safety grade. Safety grades describe the contract (mint authority, LP burn, holder count); exitability describes the depth. A token can score 100 on every safety check and still be untradeable — PROOF does exactly that in our own data. Verdicts on Solana/X1: EXITABLE, PARTIAL, COSTLY, TRAPPED, THIN, NO_POOL, UNPRICED. On EVM: EXITABLE, PARTIAL, COSTLY, THIN, NO_ROUTE, UNKNOWN. NO_ROUTE means the aggregator we check found no way out, which is strong evidence and not proof that no venue anywhere will take it; UNPRICED and UNKNOWN mean we could not resolve a value and are NOT judgements about the token. PAID: $0.004 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1; no key, no sign-up) at https://apexfaucet.xyz/api/x402/exit-check/{mint}?usd=<usd>&chain=<chain id>. Over MCP this tool answers with that price and URL, not the data.

Claim real USDC and APEX on Arc for an EVM address, three times a day, no gas needed: the operator pays. Two steps: call with only {address} to get today's challenge text; sign it with the key of that address (EIP-191 personal_sign) and call again with {address, signature}. Same claim for everyone; cooldown and daily total are enforced by a contract with no withdraw function. The day's claims open in three parts (00:00, 08:00, 16:00 UTC) and one connection claims at most once every 8 hours; a refusal names the time. The reply includes nextClaimAt (unix seconds) and claimNumber.

Look up ONE X1 token by symbol or mint address: price in XNT and USD, holders, liquidity and 24 h volume in XNT, 24 h change. A symbol returns the best search match; when several tokens share a ticker, run impostor_check first and pass the mint. For a ranked list use top_tokens. PAID: $0.003 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1; no key, no sign-up) at https://apexfaucet.xyz/api/x402/token.

Every token balance of ONE X1 wallet, read live from the X1 chain: native XNT plus SPL and Token-2022 accounts, with symbols. If a read fails the answer says it is incomplete; it never reports an empty wallet it could not read. For trading history use wallet_profile.

The latest on-chain trades of ONE X1 token, newest first (mint or symbol, up to 100). For whale-sized swaps across every token use whale_ticker; for the last 200 trades chain-wide use firehose.

Your position in the APEX/XNT pool on XDEX (or another token/XNT pool): LP balance, the XNT and tokens it is worth at tradeable reserves, and your share of the pool. Also the live price, trade fee and depth. Read from chain.

Build ONE UNSIGNED transaction that puts XNT (and the token, if the wallet holds some) into the token/XNT pool on XDEX: it uses the token first, swaps the exact rest of the XNT, and deposits both sides. Simulated for your wallet before it is returned; a swap that would move the pool more than 3% is refused and the error names the largest amount that fits. You sign it with your own key and submit it; this server never holds keys and never signs. It earns a share of trading fees; it does not change faucet claims.

Build an UNSIGNED swap transaction on X1 at the best price across XDEX and APEX AMM — direct, or two hops through XNT or APEX in ONE transaction, simulated against your wallet before it is returned. Returns base64 you sign with your own key and broadcast yourself; this server never holds your keys and never signs for you. Use mint addresses, or the string "native" for XNT. APEX mint is Du6Z596DwGnfUcMSyRHSBQzNybiQKu8GESVfruEv9Jqr. Check priceImpact before signing — thin pools move hard. Building is free. When you spend XNT (more than 0.01), the transaction includes a 0.1% platform fee to the APEX buyback wallet, shown as platformFee in the answer; otherwise you pay only the network fee.

Current XNT price in USD with its 24 h and 1 h change, read from the on-chain USDCx pool. For any other token use token_lookup.

FREE, X1. Turn one X1 wallet's on-chain transaction history into a short tune you can play: use it to give an agent a recognisable sound, or to show its activity in a fun way. Deterministic: the same history always gives the same tune. Returns { wallet, signatureCount, hasSong, key, rootMidi, bpm, wave, steps, stepSeconds, notes: [{ step, rest } or { step, midi, note, freq, vel, dur }] }; a wallet with no transactions returns hasSong false. To find wallets that already have a song, call agent_radio first.

FREE, X1. The APEX city radio line-up: the named agents of our X1 city that have a song. Returns { stations: [{ name, wallet, role }] }. Use it to pick a wallet, then call agent_tune with that wallet to get its tune as notes. No input.

Build an UNSIGNED transaction to BUY or SELL a Citizens City commodity against APEX on the on-chain commodity AMM. side is "buy" (spend APEX) or "sell" (give commodity units). For a buy, amount is APEX; for a sell, amount is whole units. Returns base64 you sign with your own key and broadcast yourself — never custodial. Call commodity_markets first for prices and depth; these pools are shallow, so check what your size does to the price before signing.

The APEX perpetual vault dead-man switch, read live from chain. 700M APEX drips weekly forever on an immutable contract (upgrade authority verified NONE). If the founder stops checking in for 28 days, 100% of every future drip goes to the PUBLIC FAUCET instead of to him — permanently, until he returns, and nobody can switch it off. Returns days remaining on the switch, the current split, and the vault's own lifetime accounting. Includes the exact getAccountInfo call to verify every figure independently.

The referral programme, open to agents on the same terms as people. Pass a wallet to see that wallet's code, referral count and earnings; pass wallet AND code to claim a code. The reward is an ongoing SHARE, not a signup bonus: you earn a percentage of every APEX claim made by anyone you referred, every time they claim, for as long as they keep claiming. It is paid in APEX from the faucet's daily budget and is capped, so it can never exceed a fixed slice of what your referrals themselves receive.

Assets that have crossed onto X1 through a bridge (WSOL.X, USDC.X), read live from the chain. Returns supply in existence, holder count, top-holder concentration, token program, whether mint and freeze authority are still live, and whether any pool exists to trade the asset in. An asset can be genuinely live on X1 and still have no market — this tells those apart. No price is synthesised from the asset home-chain value: if there is no pool here, price is null rather than a number you cannot actually get.

Launch a token on X1, or read what has been launched. Returns the live cost config (APEX burn + XNT fee + seed liquidity) and the recent launch feed. The build endpoints return unsigned transactions you sign yourself.

Given a ticker, find every token using that symbol and say which one is most likely real. 85 tickers on this chain are duplicated across 7,965 tokens — five different tokens are called XNM, and two of them have liquidity but ZERO holders and ZERO volume, which is the shape of a honeypot. Ranked by pool liquidity, then 24h volume, then holders: depth is what lets you exit, while the name and the age are what a copycat clones. Free. Resolve a token by mint address, never by ticker — this tool exists to show you why.

APEX faucet on Arc (Circle USDC chain, eip155:5042): the pot, the amount per claim (USDC + APEX), claims left today and left right now (the day's claims open in three parts, at 00:00, 08:00 and 16:00 UTC; nextReleaseAt says when), cooldown. Every number is read from the faucet contract at call time; a failed read is reported as failed, never as zero. Free.

ARC ONLY. SELL TEST AT YOUR SIZE (not a score). If I put in this much, can I get out? For a token address or Uniswap v4 pool id on Arc, at the size you pass (usdc, default 1): a real buy-then-sell round trip inside one eth_call through the pool hook (nothing spent) or, for ERC-20-USDC pools, both legs quoted. Returns whether the sell goes through, the round-trip cost, depth, whether the pool owner can pull the liquidity, and flags with reasons. The answer names its method. For one 0-100 buy score with no size needed, use arc_verdict. For up to 25 tokens in one call use arc_exit_check_bulk. PAID: $0.025 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1; no key, no sign-up) at https://apexfaucet.xyz/api/x402/arc-exit-check-bulk?ids=<token or pool id>. Over MCP this tool answers with that price and URL, not the data.

PAYWALLED. Up to 25 Arc tokens or pool ids in one call, sorted worst first (cannot sell, heavy loss, cannot buy). Returns x402 payment instructions for /api/x402/arc-exit-check-bulk ($0.025, USDC on Arc, USDC on Solana or XNT). For one token use arc_exit_check.

Put USDC to work in the APEX/USDC pool on Arc (eip155:5042) from your own key, non-custodially: call grow(minApexOut) on the ArcGrow contract with the USDC as native value; half is swapped for APEX, both halves become a full-range Uniswap v4 position minted to the caller, leftovers refunded, nothing kept. Remove any time via the PositionManager (DECREASE_LIQUIDITY or BURN_POSITION + TAKE_PAIR). With {address} this returns that address's positions, deposit and value now; without it, the contract, ABI and steps, and priceCheck: APEX's price on Arc against its price on X1. While they are more than 10% apart, do not deposit (half the USDC would buy APEX at that premium); our own page refuses then.

Does this Arc agent actually answer? The APEX Watchtower calls every endpoint of every agent in Arc's ERC-8004 identity registry once an hour: web pages, the A2A card, the MCP initialize handshake, the x402 paywall (checked against the on-chain signing domains of USDC and EURC on Arc) and the registration file itself. With an agentId: its status (up, degraded, down, not checked, listed without endpoints, no file), uptime over the hours actually measured (never counting unmeasured hours as down), typical response time, whether and how it can be paid on Arc, and what it should fix. Call it before you pay or hire an agent. Without an agentId: the counts for the whole registry. Free. Every endpoint result, the hour-by-hour history and the fix list for all agents in one call: /api/x402/arc-agent-watch ($0.004).

X1 Agent Passport: an ERC-8004 identity for your agent in the X1 Agent Registry (the Solana Agent Registry, deployed on X1 by APEX), done for you in one paid call. Returns the live price in XNT, where to pay, and the exact request. Pay the XNT to payTo from the wallet that should own the agent, then POST your {name, description, services?} to the route with the transfer signature in the X-PAYMENT header: we register the agent and hand its NFT to the paying wallet. Or register yourself for network fees only (see page).

Who actually pays whom on Arc. Every signed x402-style payment on Arc since launch, read from the chain: each EIP-3009 authorization spent on Arc USDC and every Circle Gateway batch (plain transfers carry no marker of what they paid for and are not counted). Without an address: the totals, each facilitator (the address that submits settlements, named only where the name has a source) with its kind (direct; circular, where the same wallets pay and are paid; concentrated, one payer making most of the volume; self; or contract flow), each measured and shown apart from the direct totals, and the top sellers. With an address: what that address was paid, by how many distinct payers, through which facilitators, including Circle Gateway. Free. Every facilitator, seller and payer with the latest 1,000 settlements: /api/x402/arc-x402 ($0.004).

RETIRED 1 Oct 2026: an Arc Agent Passport costs $0.99. A person pays from a browser wallet at https://apexfaucet.xyz/arc/passport/ ; an agent buys it with arc_passport_buy. This tool now only returns that answer.

Finish a passport you started before 1 Oct 2026, after the register() transaction from the old flow: pass the draft slug and the transaction hash. New passports are bought with arc_passport_buy ($0.99).

An agent buys its own ERC-8004 identity on Arc with a signature alone: $0.99 over x402, paid in USDC on Arc or Base. We host a correct registration file, mint the identity and hand it to the wallet that signed the payment, never to a typed address, and answer with the agentId and both transactions. Call once without `payment` to get the x402 terms, sign them, call again with `payment`. A refused input is never charged.

Look up an Arc Agent Passport by agentId or draft slug: its registration file, owner, endpoints, whether it is active, and its links (passport page, share picture, hourly check-up, tower in Arc City). Free.

Touchstone on Arc: on-chain assays. An assay is a real buy-and-sell of a token in one transaction, reverted, with the verdict, round-trip cost and streak written as an event by the ArcAssay contract (0x417d200a4bd83a7e3911765114b1a27ad30f8c97).

Flux Threat Intel — scam wallet and token findings on X1. The public blacklist is FREE and always will be; a paid tier (5 XNT / 30 days) adds a push alert to your wallet within seconds of a new finding, plus the full JSON feed. Every entry names what was actually observed on-chain — mint authority still live, top-holder concentration, LP not burned.

THE FRONT DOOR FOR BUYING. One catalog across everything sold here: fixed-price NFTs, NFT bonding-curve pools, APEX-quoted commodity pools, land deeds in Citizens City, buildings you can raise on the city grid, and site-wide sponsored messages. Every item carries a price in the currency you actually pay, a USD estimate, real stock, and the exact non-custodial steps to buy it. Filter with q, type, market, availability, currency and max_price. Start here instead of querying six separate systems.

The Wall — a 10,000-tile grid at /wall/. One tile is $1, bought once, kept forever: attach a label and a link and it stays. Pay either rail for the same price — XNT on X1, or USDC on Solana mainnet to the same address (X1 is a Solana fork, so there is no bridge and you never need to hold XNT). Returns live inventory, both prices, the wallet to pay, and every tile already taken. No subscription and no expiry. Outbound links are rel="sponsored nofollow noopener".

One product from the catalog by id, with its price, live stock and the exact steps to buy it. Ids look like nft-listing:nft_8, nft-pool:<pool_id> or commodity:TOMATO — list them with catalog_browse.

The NFT AMM — an arcade-style NFT marketplace where collections trade against a bonding curve instead of fixed listings. Returns live pools with floor price, curve type and how many NFTs are in each. Buy and sell without waiting for a counterparty.

How an agent buys or sells an NFT on the bonding-curve marketplace. Price moves along the curve with every trade, so read the price first.

Live Graviton Arena state for a wallet - your credit balance and the current round. BETTING IS CLOSED (18 September 2026): no stake can be placed, the pot is zero, and credits held from before can still be withdrawn. The arena itself is free to play.

Use a move in the arena — thrust (accelerate), shove (knock rivals) or brake (hold position). Moves are FREE and are made in the browser game itself - this tool cannot spend one for you, and says so. They cannot be bought at any price (the credit-paid version was closed on 18 September 2026). This is how an agent plays rather than only watching: pick a champion, then push it with moves while the round runs.
