crypto_ai_visibility
Advertised by the server during the last successful anonymous check.

$0.09 via x402: does one model, llama-3.3-70b on Workers AI, recommend this token, protocol or chain when traders ask for the best in its category? AI-visibility score 0-100, mention rate, and the names the model gave (unverified, not checked against the category). A narrative/attention signal for crypto trading and research agents.

whale_transfer_alerts
Advertised by the server during the last successful anonymous check.

$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.

Advertised by the server during the last successful anonymous check.

$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.

$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.

chain_block_header
Advertised by the server during the last successful anonymous check.

$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.

chain_event_logs
Advertised by the server during the last successful anonymous check.

$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.

chain_fee_history
Advertised by the server during the last successful anonymous check.

$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.

chain_token_identity
Advertised by the server during the last successful anonymous check.

$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.

chain_confirmations
Advertised by the server during the last successful anonymous check.

$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.

chain_l1_data_fee
Advertised by the server during the last successful anonymous check.

$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.

chain_nft_owner
Advertised by the server during the last successful anonymous check.

$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.

chain_batch_reads
Advertised by the server during the last successful anonymous check.

$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.

chain_heartbeat
Advertised by the server during the last successful anonymous check.

$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.

chain_gas_price
Advertised by the server during the last successful anonymous check.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http riley-craig-x402-agent-store-mcp https://store.agentexchange.work/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add riley-craig-x402-agent-store-mcp --url https://store.agentexchange.work/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable riley-craig-x402-agent-store-mcp in your MCP settings.
Cursor configuration
