How this service works
Return A2A endpoint readiness and skill manifest (Live x402 v2, IETF MPP & MCP endpoint at https://assay.agentdiet.dev)
Output
Returns a JSON object with a readiness status string, a letter grade, and an integer score for the target endpoint. Also includes the target URL, a boolean indicating if more paginated results exist, and an optional next_cursor for fetching additional audit records.
Example use cases
Pre-integration A2A readiness check
“Before I wire up this new agent service, can you check if https://agentdiet.dev is A2A-ready and what score and grade it gets?”
Skill manifest discovery for agent
“What skills does the A2A endpoint at https://myagent.example.com expose, and is it currently live and passing readiness checks?”
Compliance gate in agent deployment pipeline
“Run a readiness check on https://staging.mybot.io and tell me if it passes A2A compliance — I need its grade and score before I promote it to production.”
Technical details
Endpoint
GEThttps://assay.agentdiet.dev/a2a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick readiness and skill manifest summary for an A2A, MCP, or x402 endpoint — especially before integration or as a lightweight compliance gate. Prefer this over the deep audit endpoint when you only need the grade, score, status, and skill manifest rather than a full cryptographic or security analysis.
Side effects
- Target URL is unreachable or times out — status field reflects failure
- Target URL is not a valid A2A/MCP/x402 endpoint — low score or error grade returned
- Invalid cursor provided for pagination — may return empty or error response
- Required target parameter missing — request rejected with validation error
