How this service works
Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.
Output
Returns a JSON object containing a confidence score or rating for the agent card's signature fields, along with a detailed breakdown of any discrepancies, integrity assessments, and comparison results between the submitted agent card and the reference agent card.
Example use cases
Validating a new agent before onboarding
“Before I let this new A2A agent join my workflow, run a signature confidence check on its agent card and compare it against my trusted reference card — I want to know if the signature fields look legitimate.”
Auditing agent card integrity post-deployment
“I deployed an agent last week and now I want to verify its agent card hasn't been tampered with — can you run a confidence lens check comparing the current card's signatureFields to the original version I saved?”
Trust-scoring an unknown agent card from a marketplace
“I found an agent card from an unknown issuer on a marketplace — run a signature confidence analysis on it with mode check and tell me the confidence score so I know whether to trust it.”
