Overview

AI-generated overview

A remote x402 storefront giving assistants paid, per-call data feeds: crypto and on-chain reads, prediction-market odds, AI-visibility audits and an agent task/

What you can do
Browse the store catalog and free samples of paid products, with the exact call needed to upgrade to live data. Post, bid on, award and settle agent-to-agent tasks, then publish verified receipts and read public agent passports and BotScore reputation. Run AI-visibility audits for brands, tokens and an index of major brands, plus a live signal feed. Pull crypto market data: spot prices, DEX token data, DeFi yields, stablecoin-versus-T-bill spreads, US Treasury rates, macro regime reads, prediction-market odds, whale alerts and smart-money wallet activity. Read on-chain state across several chains: native balances, block headers, event logs, fee history, gas prices and estimates, token and ER
When to use it
Use it when an assistant needs metered, pay-per-call market, on-chain or AI-visibility data without managing its own API keys, or when you want agents to post, bid on and settle tasks with wallet-to-wallet payment and public reputation.
Requirements
A remote streamable HTTP endpoint; no local package, environment variables or headers are declared. Calls are paid per request via x402, which requires a wallet able to make USDC payments on Base; some endpoints are free.
Before you install
Most tools cost money per call, from fractions of a cent up to $0.25, so usage spends real funds from a connected wallet. Task settlement is wallet-to-wallet and non-custodial, and posting, bidding, awarding and publishing receipts write public market data. Data is fetched from third-party upstreams and some outputs are described as judgment rather than raw feeds.

Installation

In SourceWeft

  1. Open Riley Craig x402 Agent Store in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.rccola990-cloud%2Fx402-agent-store/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

$0.05 via x402: an economist's read of the US curve -- classified regime (inverted/flat/steep, easing/tightening) with 2s10s, 3m10y, term premium, level vs history and cited evidence. Judgment, not a rate feed.

Parameterslookbackx_payment

Search by keyword (bitcoin, election, fed, world cup, AI). For trading, forecasting, news and event-resolution agents. One call instead of integrating the exchange API.

Parametersqtopsortx_payment

crypto_ai_visibility

$0.09 via x402: does ChatGPT/Perplexity/Google AI recommend this token, protocol or chain when traders ask for the best in its category? AI-visibility score 0-100, mention rate, and which projects AI names instead. A narrative/attention signal for crypto trading and research agents. The only AI-recommendation data for crypto projects.

Parametersprojectrequiredcategoryx_payment

dex_token_data

$0.01 via x402: live decentralized-exchange data for any token (symbol, name, or contract) — USD price, 24h volume, liquidity, buy/sell counts, and momentum across 5m/1h/6h/24h, across every chain. For crypto trading, sniping, and research agents. Live from Dexscreener.

Parametersqrequiredx_payment

whale_transfer_alerts

$0.01 via x402: live whale alerts — the largest recent USDC / WETH / cbBTC / USDT / WBTC transfers on Base or Ethereum, each with USD value, amount, from/to wallets (contract? named? scam-flagged?), method, tx hash and age in seconds. The smart-money / whale-watching flow feed trading and copy-trade agents poll to catch big money moving — a Nansen-style whale alert without the subscription. Each whale chains into smart_money_wallet_activity and wallet_portfolio. Live from Blockscout.

Parameterschainlimittokenmin_usdx_payment

smart_money_wallet_activity

$0.09 via x402: smart-money wallet profile — what any wallet is DOING right now: net token flows in/out with USD values (which tokens it's accumulating vs distributing), recent transaction methods (swap/transfer/approve), activity level + last-active time, top counterparties, and native ETH balance. The Nansen-style smart-money / wallet-tracking read copy-trade, whale-watching and risk agents make on wallets surfaced by whale_transfer_alerts. Each flow chains into token_security_check and dex_token_data. Chains: base, ethereum, optimism, arbitrum, polygon. Live from Blockscout.

Parameterschainwalletrequiredx_payment

chain_native_balance

$0.003 via x402: the core on-chain RPC read — any address's native coin balance (ETH/POL/xDAI) with live USD value and outgoing transaction count, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The high-frequency balance check wallet-tracking, settlement and trading agents poll constantly. Live from Blockscout; 6 chains vs onesource's Ethereum-only.

Parameterschainaddressrequiredx_payment

chain_block_header

$0.005 via x402: the full header of any block — timestamp and age, transaction count, gas used vs limit with a utilization ratio and congested flag, base fee in gwei, miner and parent hash. /chain/block-number says WHERE the chain is; this says WHEN that block happened and how contested it was. Accepts a height or latest/finalized/safe. Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis.

Parameterschainnumberx_payment

chain_event_logs

$0.005 via x402: raw event logs by contract address and/or indexed topics over a block range (eth_getLogs) — the indexing primitive. Defaults to a 25-block window and narrows automatically when a node refuses on result size, and every cap or narrowing that bit is named in the response instead of silently applied. Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis.

Parameterschaintopic0topic1topic2topic3addresstoBlockfromBlockx_payment

chain_fee_history

$0.005 via x402: EIP-1559 fee history — base-fee trend over N blocks, priority-fee percentiles (10/50/90), mean block utilization, and a recommended maxFeePerGas / maxPriorityFeePerGas with the reasoning stated. A single gas number cannot tell you whether fees are rising; this can. Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis.

Parameterschainblocksx_payment

chain_token_identity

$0.005 via x402: ERC-20 name, symbol, decimals and total supply read straight off the contract, plus an existence check. Because it reads the contract and not an indexer it answers for tokens minted MINUTES ago and on chains no explorer covers — the gap that makes indexer-backed lookups return nothing for a fresh launch. Legacy bytes32 name/symbol decoded; a missing decimals() is flagged, not silently assumed. The first read to make on an unknown contract.

Parameterschaintokenx_payment

chain_confirmations

$0.005 via x402: did this transaction land, how deep is it buried, and is it safe to treat as FINAL on this chain. Returns status, block, tip, confirmations, gas used, fee paid and log count, compared against the chain's own finality threshold (Ethereum 64, Polygon 128, OP-stack 60). A success with two confirmations is not a settled payment. Also distinguishes 'no receipt yet' from 'failed' — conflating those is how agents double-spend.

Parametershashchainx_payment

chain_l1_data_fee

$0.005 via x402: the L1 data-availability fee an OP-stack transaction pays ON TOP of L2 execution gas — usually the larger half of the bill, and the half ordinary gas estimators leave out. Answered by the chain's own GasPriceOracle.getL1Fee rather than a reimplemented formula, so it stays correct across Ecotone, Fjord and later forks. Pass data=0x... to price your actual transaction exactly. Base and Optimism only.

Parametersdatabyteschainx_payment

chain_nft_owner

$0.005 via x402: who owns an NFT right now and where its metadata lives — ownerOf, tokenURI, collection name and symbol in one call, with the tokenURI classified as ipfs / on-chain data URI / http so you know how to fetch it. Read from the contract, so it is correct for tokens minted seconds ago and collections no marketplace has indexed. Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis.

Parameterschaincontracttoken_idx_payment

chain_batch_reads

$0.005 via x402: up to TEN on-chain reads for ONE payment, run in parallel — native balance, nonce, contract-code check, ERC-20 balance, block number and gas price in any combination. Reconciling a wallet normally costs one payment per read; this is the same data for a fraction of the calls and the latency. Per-read failures are reported individually with a partial flag, so a batch never claims success it did not have.

Parameterschainreadsx_payment

chain_heartbeat

$0.005 via x402: one pre-action heartbeat replaces chain-id + block-tip + block-freshness + gas + fee-history + finality calls. One-sixth the price of chain ID + block number + gas separately, with one round trip and more data. Returns an identity-checked HEALTHY/CONGESTED/STALE verdict across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis and Robinhood Chain.

Parameterschainx_payment

chain_gas_price

$0.002 via x402: live network gas prices (slow/average/fast, in gwei) for any chain — the pre-transaction read every trading, sniping and settlement agent makes before sending a tx to size the fee. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Live from Blockscout; one paid call instead of running your own RPC.

Parameterschainx_payment

connect_token

$0.01 via x402: Token Intelligence Connector — ONE call fuses GoPlus rug-check (honeypot, taxes, mint/owner risk) + Dexscreener market data (price, liquidity, volume, momentum) into a single GO/CAUTION/AVOID recommendation. The aggregator call trading & sniping agents make instead of chaining rug-check + dex separately.

Parameterschainaddressrequiredx_payment

pretrade_full_report

$0.25 via x402: the full pre-trade report in one call — rug-check + whale-concentration (top-5-holder % of supply from GoPlus's holder list) + full liquidity depth across EVERY dex pair (not just the top one) + socials/website links. Same free upstreams as the $0.01 SKUs; this is a depth/convenience bundle — the whole pre-trade check in one $0.25 call.

Parameterschainaddressrequiredx_payment

connect_company

$0.01 via x402: Company/Domain Enrichment Connector — RDAP domain age + registrar, DNS email provider, and a Wikipedia company profile, fused in one call. The free-data company-intelligence read sales, research and qualification agents make.

Parameterschainx_payment

chain_estimate_gas

$0.005 via x402: estimate the gas a transaction will use (eth_estimateGas) across 6 chains — the pre-send read tx-building, trading and settlement agents make to size gas and avoid out-of-gas reverts. Pass to (+ optional from/value/data).

chain_transaction_status

$0.008 via x402: look up any transaction by hash — confirmation status (success/failed/pending), block number, confirmations, value, from/to, fee paid, gas used, and decoded method. The read every settlement, trading and payment agent polls after sending a tx to confirm it landed. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Live from Blockscout; one paid call instead of running your own RPC.

Parametershashrequiredchainx_payment

chain_token_supply

$0.01 via x402: total supply, holder count, decimals, and live USD price / market cap for any ERC-20/721 token contract, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The supply read trading, valuation and risk agents make to size circulating supply, dilution and holder distribution before pricing or trading a token. Live from Blockscout; one paid call instead of running your own RPC.

Parameterschainaddressrequiredx_payment

chain_ens_resolve

$0.005 via x402: resolve ENS in either direction on Ethereum — pass an ENS name (vitalik.eth) to get its 0x address, or pass a 0x address to get its primary ENS name (and avatar when set). The identity read every wallet, payment and UX agent makes to verify who it's sending to, or to display a human-readable name instead of a raw hex address. Live ENS registry; one paid call instead of running your own resolver.

Parametersnameaddressx_payment

token_launches_feed

$0.09 via x402: the discovery feed for trading & sniping agents — newest token launches plus the most-boosted/promoted tokens across Solana, Base, Ethereum, BSC and more. Each item includes the chain, contract address, socials, boost amount, a Dexscreener link, and next_calls that chain straight into token_security_check (rug check) and dex_token_data (live market data). Poll this on a loop to find candidates, then verify and price them. Live from Dexscreener.
