api record

This server exposes one tool, verify_schema: structural and integrity verification of JSON against a JSON Schema. It does not judge whether content is correct or true. Each result carries a signed attestation whose public key is published at /.well-known/agent-card.json. After a small free daily trial, calls require x402 payment.

_ 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.

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. How it is counted.

_ what it can do 2 tools
2 never probed 0 of 2 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.

  • verify-schema unknown never probed

    General-purpose JSON Schema validation service. Validates any JSON value — agent tool outputs, API responses, generated documents, configuration payloads, or data exchanged between agents — against a caller-supplied JSON Schema (draft-04 through 2020-12) and returns every violation found, not just the first. Read-only: never modifies the submitted data. Priced at $0.02 USDC per call via the x402 protocol (HTTP 402 Payment Required).

  • trust-score unknown never probed

    Trust score for an agent_id, v1: a recency-weighted pass rate over that agent's verification history on this service, as a raw float in [0, 1], with a 95% confidence interval, the sample size, and a signed attestation. A statistical signal about past structural verification results only: it says nothing about whether the agent's content is correct, and it is not a guarantee of future behavior or of overall trustworthiness. agent_id is an unauthenticated label (the response says so: identity_verified is false). Agents with no history return trust_score null with reason 'no_data' (still charged: it is an answer). Priced at $0.01 USDC per call via the x402 protocol. Endpoint: GET https://fastapi-service-5ag4.onrender.com/score/{agent_id}.

_ 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.

card completeness
50%

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.
