api record

Agent Risk Desk: EVM address enrichment, counterparty-risk checks for EVM and NEAR, Allowance receipt verification and transaction screening. Paid tools cost USDC on Base per call through x402 (MCP transport: payment in _meta["x402/payment"]). list_services is free.

_ is it live, free and safe measured by this hub
Is x402-services live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is x402-services free to use?
Yes — the hub reached it with no key and no payment.
What tools does x402-services have?
6 tools: enrich_evm_address, verify_allowance_receipt, list_services, counterparty_risk_evm, counterparty_risk_near, screen_transaction.
Is x402-services safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 6 tools
6 never probed 0 of 6 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • enrich_evm_address unknown never probed

    Profile of an EVM address on Base, Ethereum, OP Mainnet or Arbitrum in one call: EOA, contract or EIP-7702 account, age, transactions sent, native and major token balances (USDC, USDT, EURC, DAI, WETH, BTC), Sourcify-verified source and name, proxy and implementation, token metadata, labels (OFAC SDN, Chainalysis oracle, known issuers) and a risk verdict with reasons. Useful to know who an address is before paying, listing or trusting it. Price: $0.01 USDC per call (x402).

  • verify_allowance_receipt unknown never probed

    Seller-side check that an Allowance vault receipt on NEAR paid a given account at least a given amount, bound to the seller request hash, at final finality. Returns valid or the reason (not paid yet, wrong payee, amount, asset or request, unknown receipt, not a vault) and the vault code hash read at the same block. Price: $0.005 USDC per call (x402).

  • counterparty_risk_near unknown 1h ago

    Counterparty-risk verdict (allow, warn or block, with reasons) for a NEAR account, for use before paying it. Checks the OFAC SDN list and operator deny-lists, whether the account exists, its age, its contract code and code changes in the last 72 h, global contracts whose publisher can change them, and, with an Allowance vault, the vault denylist and payment history. Price: $0.02 USDC per call (x402).

  • screen_transaction unknown 1h ago

    Plain-language explanation of an EVM or NEAR transaction: status, method, native and token transfers, approvals (unlimited ones flagged), fee, and a risk verdict for each counterparty, with a one-line summary. Covers Base, Ethereum, OP Mainnet, Arbitrum, Base Sepolia and NEAR. Useful to check what a payment or approval really did. Price: $0.04 USDC per call (x402).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id f10da28ad48c4b98.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f10da28ad48c4b98/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
