Source-grounded, benchmarked on AVeriTeC, with a signed receipt anyone can verify offline. When your agent makes a claim, we check whether it's actually true — before it acts.

Works with Claude Desktop, Cursor, and Windsurf. Verify before you act.
Don't take our word for it. We hand you the bytes. The math is yours.
This sample carries two of the three signers (Presidio's leg signs offline against a fixed canonical, public on x402#2332). Same recompute chain re-verified independently by the public preaction-governance-conformance board — not by us, with the steps published.
Every /evaluate response is committed to a published JWS receipt format. Anyone can verify offline against our public JWKS — no AgentOracle service required.

Building a platform that needs verification as a primitive? Volume pricing available for high-throughput integrations. Includes white-label receipt branding, custom mapping documents under your namespace, priority support, and a dedicated integration channel.
Open-source verifier on PyPI: pip install agentoracle-receipt-verify — your end users get the same offline cryptographic guarantees regardless of which platform issued the receipt.
Everything you need to know before integrating.
