last good check
of 8 tools
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.

Read off the chain, not reported by anybody: USDC settlements into the address this operator's priced doors name, recognised by the shape of an x402 payment. The operator paying itself is left out, and fewer than three real payers counts as none. This address also stands behind 1 other origin: the figure is the gateway's, not this listing's alone. How it is counted.

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.
erc8004-validate paid never probed
POST /erc8004/validate turns a settled receipt into a score (0–100) for a registered agent_id.
a2a-message paid never probed
POST /a2a-message is the A2A card URL. Same x402 floor and chat fulfillment as /v1/chat/completions. Returns a signed receipt: hub, model, amount, verify_url. No account. No API key. A wallet that can pay the 402 is enough. You hold hub, model, and amount. Unauthenticated POST {} returns HTTP 402. Collected rows are bookable via GET|POST /v1/agents/:agent_id/book.
chat-completions paid never probed
POST /v1/chat/completions (bot drop-in). Returns a signed receipt: hub, model, amount, verify_url. Cost-plus, quoted, receipted — USDC on Base or Solana. No account. No API key. A wallet that can pay the 402 is enough. Unauthenticated GET or POST {} returns HTTP 402. You hold hub, model, and amount.
register-agent paid never probed
POST /v1/agents/register is fail-closed: bind an AAWP official or smart-account agentWallet to an integer agent_id using a collected HMAC-valid receipt. Demo receipts do not qualify.
foreign-ingest paid never probed
POST /v1/agents/:agent_id/book/ingest — spent elsewhere → stamp here. Record x402 spend at another shop on the possession book. Possession-gated (401 without session; not a public 402 settle). On-chain USDC verify (fail closed). evidence foreign_ingest. Returns verify_url like native completions. See GET /openapi.json and llms.txt Foreign ingest.
responses paid never probed
POST /v1/responses (bot drop-in). Same x402 + signed receipt as /v1/chat/completions. Accepts input (string or message array), max_output_tokens. Returns Responses-shaped output + Chit receipt with verify_url. Stateless one-shot. Unauthenticated → HTTP 402.
agent-book paid never probed
GET|POST /v1/agents/:agent_id/book returns last-N collected spend for that agent_id, plus budget Y (cap), spent, and remaining under a prepaid ceiling. Possession-gated (register session or HMAC). Set budget with POST { session, budget }. Not a public index. You hold hub, model, and amount.
models paid never probed
GET /v1/models lists OpenAI-shaped model ids for the drop-in /v1 door (install path, not the product). Public, no key.
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.
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.
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.
