Verify web evidence for citations
Receive timestamped, cryptographically verifiable proof that a specific URL is live and contains expected content, enabling trusted citation in agent outputs.
How it works
Read-onlyResearch and knowledge
The agent identifies a URL that needs to be cited or verified for accuracy. It calls the verify_web_evidence tool with the target URL and expected status/text. The agent reviews the returned receipt ID, content hash, and observation timestamp to confirm the evidence is valid before including the citation in its final response.
