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://email-verify.agentdiet.dev/v1/paywall-check)
Output
Returns a structured audit report covering: JSON-RPC protocol compliance status, measured response latency vs SLA thresholds, OpenAPI schema presence and validity, and HTTP 402 / x402 settlement header conformance — with pass/fail indicators for each dimension.
Example use cases
Pre-launch MCP server compliance check
“Before I go live, can you audit my MCP server at https://tools.mycompany.ai/mcp to make sure it's JSON-RPC compliant, has a valid OpenAPI schema, and meets latency SLA requirements?”
HTTP 402 paywall header verification
“I set up an x402 paywall endpoint at https://api.myservice.dev/v1/resource — can you check whether it returns the correct HTTP 402 settlement headers according to the IETF MPP spec?”
Third-party agent endpoint due diligence
“I'm about to integrate with a vendor agent at https://partner-ai.io/agent/v2 — can you run a full SLA and protocol compliance audit on it so I know if it's production-ready?”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/paywall-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a multi-dimensional protocol compliance audit of a remote agent, MCP server, or x402 paywall URL in a single call — covering JSON-RPC format, latency SLA, OpenAPI schema, and HTTP 402 header conformance together. Prefer this over manual probing or generic HTTP health checks when evaluating agent infrastructure readiness or vetting third-party integrations against A2A/MCP/x402 standards.
Side effects
- Target URL is unreachable or returns a network error — audit fails with connectivity error
- Target URL is not an A2A/MCP/x402 endpoint — returns non-compliant or unrecognized protocol response
- Target endpoint has extremely high latency causing audit timeout
- Malformed or missing OpenAPI schema at target — schema validation portion fails
- HTTP 402 headers absent or malformed on a non-paywall endpoint — 402 check fails as not applicable
