How this service works
Audits any remote agent or MCP URL for JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP 402 settlement headers. (Live x402 v2, IETF MPP & MCP endpoint at https://agentdiet.dev/v1/preflight/certify)
Output
Returns a structured audit report covering JSON-RPC compliance status, measured latency vs SLA thresholds, OpenAPI schema validation results, and HTTP 402 payment settlement header inspection for the provided target URL
Example use cases
Pre-production MCP server certification
“Before I go live, can you audit https://staging.myapp.io/mcp to make sure it passes JSON-RPC compliance, has valid OpenAPI docs, and the latency is within SLA?”
Debugging a broken x402 payment endpoint
“My x402 payment agent at https://pay.myservice.dev/v1/agent keeps failing — can you run a preflight audit on it and tell me if the HTTP 402 settlement headers are set correctly?”
Third-party A2A agent trust verification
“I want to integrate this third-party agent at https://partner-ai.com/a2a — can you certify whether it's properly compliant with the A2A protocol and x402 payment headers before I connect it to my system?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/preflight/certify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific A2A agent, MCP server, or x402 HTTP 402 payment endpoint meets protocol compliance standards before integration or deployment. It is the right choice when you need a combined audit covering JSON-RPC spec adherence, latency SLA measurement, OpenAPI schema validity, and HTTP 402 payment header correctness in a single call, rather than running separate per-protocol checks.
Side effects
- Target URL is unreachable or returns a connection error
- Target URL does not implement any recognized protocol (A2A, MCP, x402)
- Invalid or malformed URL provided in the query parameter
- Target endpoint times out before audit completes
- Remote service blocks probing requests (firewall, auth, rate-limit)
