api record

Every tool is paid per call with x402 (USDC on Base or Solana). Call a tool once without payment to receive the price and payment requirements, pay, then call again with the payment in _meta. Failed calls are never charged.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • agent_trust_wallet unknown never probed

    Who is this agent wallet? For sellers and marketplaces deciding whether to serve, rate-limit or extend credit to a buyer. Base activity (transactions, recent USDC transfers, micro-payment behaviour, distinct counterparties, USDC balance, ENS/Basename), ERC-8004 agent identities it owns with on-chain feedback, and a 0-100 trust score with tier and recommendations. Price: $0.01 per call.

  • agent_trust_agent unknown never probed

    ERC-8004 agent by id on Base: owner, verified agent wallet, registration URI and its resolved JSON (name, endpoints, skills), feedback count and average from the Reputation Registry, distinct clients and the latest feedback entries. Use to vet a counterparty agent before hiring or paying it. Price: $0.01 per call.

  • agent_trust_domain unknown never probed

    Agent-readiness and identity profile of a domain: Web Bot Auth key directory (RFC 9421), A2A agent card (name, skills, extensions), MCP well-known manifest, llms.txt, robots.txt, and whether the root answers HTTP 402 with x402 payment requirements (and on which networks). Use to decide whether a counterparty domain is a real agent service and how to talk to it. Price: $0.01 per call.

  • agent_trust_verify_request unknown never probed

    Verifies a Web Bot Auth signed HTTP request (RFC 9421 HTTP Message Signatures) against the signer's public key directory: pass the request method, URL and the Signature, Signature-Input and Signature-Agent headers you received; get back whether the signature is valid, which agent directory signed it and the key id. For sellers who cannot run the verification library themselves. Price: $0.005 per call.

_ try it over a2a 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
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.

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