# AgentTrial > AI agents make claims. AgentTrial makes them prove it. AgentTrial is an autonomous adversarial evaluator for AI agents. It extracts typed claims, seals a trial plan before execution, runs bounded scenarios, evaluates deterministic assertions, and signs a tamper-evident evidence receipt. ## Key pages - /methodology — scoring and coverage rules - /security — authorization and responsible-use boundaries - /developers — API quickstart - /openapi.json — OpenAPI 3.1 schema - /.well-known/agenttrial.json — machine-readable descriptor - /verify — local receipt verifier ## Important Receipts describe bounded observed behavior. They are not legal certification or a guarantee of safety. Arbitrary public targets are passive-only. A2A lifecycle operations are not currently advertised.
