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://x402-audit.agentdiet.dev/v1/preflight)
Output
Returns a structured audit report covering JSON-RPC protocol compliance status, measured latency vs. SLA thresholds, OpenAPI schema validity findings, and HTTP 402 x402 payment header presence and correctness for the target URL.
Example use cases
Pre-deployment MCP server audit
“Before I go live, can you run a compliance check on https://staging.myapp.dev/mcp and confirm it passes JSON-RPC spec, has acceptable latency, and has correct HTTP 402 headers?”
Third-party A2A vendor vetting
“I'm considering integrating with a vendor agent at https://vendor-agent.example.com/a2a — can you audit it for SLA compliance and x402 payment header correctness before I commit?”
Ongoing x402 endpoint health check
“Can you check whether https://payments.myservice.io/v1/agent still has valid x402 v2 settlement headers and is meeting its latency SLA right now?”
Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific A2A, MCP, or x402 service URL actually implements the protocol correctly end-to-end — covering JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP 402 payment headers — rather than just checking availability or doing a generic HTTP health check.
Side effects
- Target URL is unreachable or times out — audit returns connectivity failure
- Invalid or malformed URL provided — returns validation error
- Target endpoint returns unexpected content type — schema audit may be inconclusive
- HTTP 402 headers absent or malformed — flagged as non-compliant but not an auditor error
- Rate limiting or auth on target endpoint may prevent full audit completion
