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 compliance report object covering JSON-RPC spec adherence, measured latency vs SLA thresholds, OpenAPI schema validity, and HTTP 402 / x402 payment settlement header presence and correctness for the audited endpoint URL
Example use cases
Pre-deployment MCP server compliance check
“Before I publish my MCP server, can you run a full compliance audit on https://staging.mytools.dev/mcp to verify it's JSON-RPC compliant and has correct HTTP 402 headers?”
Third-party agent SLA verification
“I'm about to integrate a third-party agent at https://vendor-agent.io/v1/a2a into my workflow — can you audit it for latency SLA and protocol compliance first?”
x402 payment header validation
“Can you check whether https://api.payableagent.com/v1/tools properly returns x402 payment settlement headers and passes the OpenAPI schema validation?”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/preflight/certify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need programmatic, machine-readable compliance verification of an A2A, MCP, or x402-capable agent URL — especially when checking JSON-RPC correctness, HTTP 402 payment header conformance, or latency SLA before integrating a remote agent into a workflow. Prefer this over manual inspection or generic HTTP health checks when you need structured audit output covering multiple protocol layers simultaneously.
Side effects
- Target URL unreachable — network timeout or DNS resolution failure
- Target URL returns non-HTTP 200/402 response that cannot be parsed
- Malformed or missing URL parameter — 400 Bad Request
- Target endpoint does not expose an OpenAPI schema — partial audit only
- Rate limit or payment failure — HTTP 402 on the auditor itself
