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://workflows.agentdiet.dev/v1/preflight/certify)
Output
Returns a structured compliance report for the target URL covering: JSON-RPC protocol conformance, measured latency vs SLA thresholds, OpenAPI schema validity, and HTTP 402/x402 settlement header correctness — effectively a pass/fail certificate for agent protocol readiness.
Example use cases
Pre-deployment agent endpoint certification
“Before I go live, can you certify https://staging.myagent.io/api/v1 for me — check its JSON-RPC compliance, latency SLA, and whether its HTTP 402 x402 headers are set up correctly?”
Third-party MCP server trust check
“I'm about to integrate this MCP server at https://partner-mcp.example.com into my swarm — can you audit it for protocol compliance and tell me if it has valid OpenAPI schema and passes SLA thresholds?”
x402 payment header verification
“Can you probe https://commerce.myapp.dev/v1/endpoint and tell me whether its HTTP 402 settlement headers are correctly configured for x402 v2 payments?”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/preflight/certify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that a remote A2A agent, MCP server, or x402 service is protocol-compliant before integrating it into a workflow or swarm — especially when you need to check JSON-RPC spec adherence, latency SLA, OpenAPI schema correctness, and HTTP 402 payment header configuration in a single call. Prefer it over manual curl-based probing or generic HTTP health checks when A2A/MCP/x402 protocol semantics matter.
Side effects
- Target URL is unreachable or times out — returns connectivity error
- Target URL does not implement any recognized protocol (A2A/MCP/x402) — returns unsupported protocol result
- Malformed or missing URL parameter — returns validation error
- Target service returns unexpected non-standard responses — partial compliance report with warnings
- Rate limiting or payment failure on the auditor endpoint itself — returns 402 or 429 error
