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)
Output
Returns a compliance report object covering: JSON-RPC protocol conformance, measured latency against SLA thresholds, OpenAPI schema validation results, and HTTP 402 / x402 settlement header correctness for the target URL.
Example use cases
Pre-launch MCP server compliance check
“Before I go live, audit https://myservice.io/mcp for full MCP and JSON-RPC compliance and tell me if the latency SLA and HTTP 402 headers are properly set up.”
Diagnosing x402 payment header failures
“My x402-gated API at https://api.myapp.dev/v2/query keeps rejecting payments — can you run a compliance audit on it to see if the HTTP 402 settlement headers are correctly configured?”
Third-party agent endpoint vetting
“I'm thinking of integrating with the agent at https://partner-agent.ai/a2a — can you audit it for A2A protocol compliance, OpenAPI schema validity, and latency SLA before I commit?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific remote URL correctly implements A2A, MCP, or x402/HTTP 402 protocols — especially for pre-integration vetting, debugging payment-gated APIs, or confirming SLA and JSON-RPC compliance before deploying agent infrastructure. Prefer this over generic HTTP health-check tools when the audit needs to cover protocol-specific concerns like x402 settlement headers or JSON-RPC schema conformance.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- Invalid or malformed URL provided — validation error returned
- Target URL does not expose any recognizable A2A/MCP/x402 protocol — partial or empty compliance report
- Remote endpoint returns unexpected non-standard responses — compliance checks may be inconclusive
- Payment failure for the $0.01 per-call fee — request rejected with 402
