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://serp-extract.agentdiet.dev/v1/preflight/certify)
Output
Returns a structured compliance report covering: JSON-RPC protocol conformance, measured latency against SLA thresholds, OpenAPI schema validity assessment, and HTTP 402 / x402 payment settlement header analysis — effectively a certification snapshot of the target endpoint's readiness.
Example use cases
Pre-deployment MCP server certification
“Before I go live, can you audit my MCP server at https://tools.mycompany.dev/mcp and tell me if it's JSON-RPC compliant, passes latency SLA, and has valid OpenAPI schema?”
HTTP 402 payment header verification
“I set up x402 payment settlement on https://api.myagent.io/v1/tool — can you certify whether the HTTP 402 headers are correctly configured for USDC settlement?”
Third-party A2A agent due diligence
“I'm thinking of integrating a third-party agent at https://partner-agent.io/a2a — can you run a compliance check on it and tell me if it meets JSON-RPC and SLA standards before I connect it to my workflow?”

Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/preflight/certify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a remote A2A agent, MCP server, or x402-enabled HTTP endpoint is properly spec-compliant before integration, deployment, or payment routing — especially when you need a single call that covers JSON-RPC correctness, OpenAPI schema validity, latency SLA, and HTTP 402 payment header compliance simultaneously rather than running separate checks.
Side effects
- Target URL is unreachable or returns non-2xx/402 — audit fails with connectivity error
- Target URL is not a valid agent/MCP endpoint — JSON-RPC compliance check fails with schema mismatch
- Extremely slow or timing-out target — latency SLA check records failure
- Malformed URL input — validation error on the required url field
- Target endpoint blocks probing requests — partial or empty compliance result returned
