How this service works
Execute A2A JSON-RPC 2.0 message/send or tasks/send task (Live x402 v2, IETF MPP & MCP endpoint at https://assay.agentdiet.dev)
Output
Returns a JSON object containing a status string, a letter grade (e.g. A, B, C), an integer conformance score, the target URL that was audited, and optional pagination fields (has_more, next_cursor) for retrieving additional audit records.
Example use cases
Pre-deployment A2A endpoint validation
“Before I go live, can you execute a tasks/send call against https://myagent.example.com and tell me the protocol conformance grade and score so I know it's ready?”
Third-party agent trust check
“I'm about to integrate with a partner's agent at https://partner.agentplatform.io — can you send a live A2A JSON-RPC 2.0 message/send task to it and give me its TDQS reputation score and grade?”
Continuous CI audit of agent endpoint
“As part of my pipeline, can you execute a JSON-RPC 2.0 tasks/send against https://staging.mybot.dev and return the status and score so I can fail the build if it doesn't pass?”
Technical details
Endpoint
POSThttps://assay.agentdiet.dev/?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to execute a live A2A JSON-RPC 2.0 message/send or tasks/send call against a specific agent endpoint and receive a graded, scored conformance and security report. It is distinct from static audit or manifest-fetching endpoints because it actively sends a task payload and measures the live response for protocol compliance, TDQS reputation, and security posture.
Side effects
- Invalid or unreachable target URL returns an error status with a failing grade
- Malformed JSON-RPC payload may result in a protocol-level rejection
- Target endpoint timeout causes a failed status response
- Invalid pagination cursor returns an error or empty result set
- Missing required 'target' parameter results in a 422 or 400 validation error
