JSON Schema Verifier

Endpoints (3 live)

• GET /score/1 — 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). (0.01 USDC on Base)
