How this service works
Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.
Output
A JSON object containing a trust and compatibility assessment of the submitted A2A agent card, including policy compliance results, mode compatibility findings, and any detected anomalies or mismatches relative to a reference card if provided.
Example use cases
Vetting an unknown marketplace agent
“I found an agent card from 'bazaar-unknown-agent-7' on a public marketplace — can you run a trust radar check on it against my buyer policy to see if it's trustworthy before I connect?”
Comparing agent card to reference baseline
“I have a new version of an agent card from 'internal-data-service' and a reference version I trust — can you check whether the new one still matches my expectations for text input and structured JSON output modes?”
Policy compliance audit before agent handoff
“Before I hand off tasks to this external agent, run a trust radar check on its agent card JSON against our strict buyer policy and tell me if there are any red flags or policy violations.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/x402-a2a-agent-card-trust-radarWhen to prefer
Choose this endpoint when an AI agent needs to perform due diligence on an A2A agent card before establishing a connection or delegating tasks, especially when a buyer policy must be enforced or when comparing against a known-good reference card. Prefer this over generic schema validators when the use case is specifically about agent-to-agent trust, mode compatibility, and policy adherence in blockchain-native agent ecosystems.
Side effects
- Missing required fields (agentCardJson or sourceLabel) returns a validation error
- agentCardJson exceeds maxProperties:50 limit causing rejection
- Malformed JSON in agentCardJson or buyerPolicy
- Policy object conflicts produce indeterminate results
- x402 payment failure or insufficient USDC balance blocks the call
- Reference card mismatch causes comparison to fail if schema is incompatible
