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://preflight.agentdiet.dev/v1/402-compliance)
Output
Returns a structured compliance report covering: JSON-RPC protocol conformance, observed latency vs SLA thresholds, OpenAPI schema validity, and HTTP 402/x402 payment settlement header correctness for the submitted URL, with specific pass/fail indicators and any detected issues.
Example use cases
Pre-deploy MCP tool compliance check
“Before I ship my new MCP server at https://tools.mycompany.dev/v1/mcp, can you run a full compliance audit — JSON-RPC, OpenAPI schema, and HTTP 402 headers — and flag anything that would break agent interoperability?”
Debugging broken x402 payment headers
“My x402 endpoint at https://api.myservice.io/v1/search keeps failing payment settlement — can you audit it and tell me exactly what's wrong with the 402 headers?”
SLA verification for a third-party A2A agent
“I'm about to integrate a third-party agent at https://partner.agentplatform.com/a2a — can you check its latency SLA and protocol compliance before I sign off on the integration?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/402-compliance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that a remote A2A agent, MCP server, or x402-enabled API is properly configured for agent interoperability — specifically checking JSON-RPC correctness, latency SLA, OpenAPI schema presence, and HTTP 402 payment header compliance. It is the right choice over generic HTTP probing tools when your concern is agent-protocol-specific compliance rather than general uptime or content checking.
Side effects
- Target URL is unreachable or times out — audit cannot complete
- URL does not expose any recognized A2A, MCP, or x402 protocol surface — limited or no compliance data returned
- Malformed or missing url parameter — request rejected with validation error
- Target endpoint returns unexpected non-standard responses — partial compliance data only
- Rate limit or payment failure for the $0.01/call fee — HTTP 402 returned to caller
