How this service works
Adjudicate a closed-set claim about a run (model_is, cost_le, no_tool_host, output_digest_at_step, step counts, status, run id) to supported | contradicted | unknown with the deciding evidence path.
Output
Returns a verdict of 'supported', 'contradicted', or 'unknown' for the submitted claim, along with the deciding evidence path that led to that determination — enabling downstream auditing, dispute resolution, or compliance logging.
Example use cases
Auditing model identity after a run
“I need to confirm whether the agent run with ID run-7f3a9b really used claude-3-5-sonnet as claimed — can you check that and tell me if it's supported or contradicted, with the evidence?”
Cost-cap compliance check
“Our policy says no single run should cost more than $0.05 USDC — can you verify that run oid-xyz789 actually stayed under that threshold and show me the evidence path?”
Output integrity verification at a specific step
“I want to know if the output digest 'sha256:abcdef…' is accurate at step 4 of run oid-def456 — is that claim supported, contradicted, or unknown?”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/tine/claim-verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, machine-verifiable adjudication of a specific factual claim about an AI agent run — particularly when the claim is from the closed set (model identity, cost, tool host, output digest, step count, status, run ID). Prefer this over general attestation endpoints when you need a verdict (supported/contradicted/unknown) rather than a raw attestation object, and when you need the deciding evidence path included in the response.
Side effects
- Claim references a run ID that does not exist — returns unknown or 404-equivalent
- Insufficient evidence available to resolve claim — returns 'unknown' with empty evidence path
- Malformed claim body or missing required fields — returns validation error
- Payment not received or insufficient — x402 payment required error
- Claim type not in the supported closed set — returns error or unknown
