How this service works
Execute A2A JSON-RPC 2.0 task (Live x402 v2, IETF MPP & MCP endpoint at https://assay.agentdiet.dev)
Output
Returns a status string, a letter grade (e.g. A, B, C), an integer score, the target URL, and optional pagination fields (has_more boolean and next_cursor string) for fetching additional audit records.
Example use cases
Pre-deployment A2A endpoint certification
“Before I go live, can you audit https://myagent.example.com/a2a and tell me its security grade and TDQS score so I know it's ready for production?”
Third-party MCP server vetting
“I'm about to integrate with an MCP server at https://partner.example.com/mcp — can you run an A2A JSON-RPC audit on it and give me a compliance score before I commit?”
Ongoing x402 endpoint health check
“Check https://payments.example.com/x402 against A2A and TDQS standards and let me know its current grade and whether there are more audit records to page through.”
Technical details
Endpoint
POSThttps://assay.agentdiet.dev/a2a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a machine-readable security grade and TDQS score for an A2A, MCP, or x402 endpoint via a standard JSON-RPC 2.0 task invocation — especially when you need idempotent, paginated audit results. Prefer this over the deeper audit endpoint when a quick grade and score suffice and you don't need exhaustive protocol-level findings.
Side effects
- Invalid or unreachable target URL returns an error status
- Missing required 'target' parameter causes a 400-level rejection
- Target endpoint that does not speak A2A/MCP/x402 may return a low score or error status
- Network timeouts against slow target endpoints
- Pagination cursor mismatch if audit state changes between pages
