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://mcp-security.agentdiet.dev/v1/x402-mpp-paywall-verifier)
Output
Returns a structured compliance report covering JSON-RPC protocol adherence, measured latency against SLA thresholds, OpenAPI schema validation findings, and HTTP 402 x402 v2 / IETF MPP settlement header correctness for the target URL.
Example use cases
Verify x402 paywall before integration
“Before I integrate this payment-gated API into my pipeline, can you check whether https://api.partner.com/v1/data-feed has proper HTTP 402 x402 v2 headers and IETF MPP compliance?”
MCP server JSON-RPC health check
“I just deployed my MCP server at https://mcp.myapp.io/rpc — can you audit it for JSON-RPC spec compliance and tell me if the latency SLA looks acceptable?”
Pre-launch agent endpoint audit
“We're about to go live with our A2A agent at https://agents.mycompany.dev/a2a — can you run a full compliance audit to check OpenAPI schema validity, JSON-RPC conformance, and HTTP 402 settlement headers before we launch?”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/x402-mpp-paywall-verifier?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that a specific remote agent, MCP server, or x402 paywall URL conforms to JSON-RPC, OpenAPI, HTTP 402 x402 v2, and IETF MPP protocol standards — especially before integrating a third-party agent endpoint or before launching your own. Prefer this over generic uptime monitors when protocol-level compliance (not just liveness) is what matters.
Side effects
- Target URL unreachable or returns network error — audit fails with connectivity error
- Target URL returns unexpected content type (e.g. HTML instead of JSON) — JSON-RPC compliance check fails
- Malformed or missing URL parameter — request rejected with validation error
- Target service too slow to respond — latency SLA flagged as failed
- x402 headers absent or malformed — HTTP 402 compliance reported as non-conformant
