About Agent Oracle

Agent Oracle is a machine-native service that gives autonomous AI agents access to live web data with source citations and verified information, returned as structured JSON. It uses x402 HTTP-native micropayments so agents pay $0.02 per query in USDC on the Base blockchain, requiring no API keys, accounts, or subscriptions. Research is powered by Perplexity Sonar and deployed on Vercel Edge for sub-second responses.

Commonly Cited Strengths & Limitations

Strengths

Receipts verify offline against published keys with no account or trust in the vendor
Tamper-evident: changing one byte or backdating fails the signature
Reference verifier is MIT-licensed, under 250 lines, and dependency-free
Format is byte-identical across independent implementations and IETF-filed

Limitations

A signed receipt doesn't prove the verified claim is actually true — the signature establishes who issued a determination, not whether that determination is correct; for judgement-based checks it's a non-repudiable commitment to an opinion, not evidence the opinion is right
An issuer holding a valid key can sign a receipt over any content, including content it never actually verified
An agent can return a valid source and still produce a conclusion the retrieved evidence doesn't actually support
Published FEVER benchmark results are Wikipedia-grounded and test static knowledge rather than the live-web claim verification that is the product's actual design goal, with parametric-knowledge contamination a live risk on modern models

Common Use Cases

Verifying an agent's claim before consequential actions
Independent/offline verification of agent decisions by third parties
Compliance and audit trails for agent actions
Satisfying traceability requirements (e.g. EU AI Act high-risk systems)
