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://shopify-spy.agentdiet.dev/v1/paywall-check)
Output
Returns a structured audit report covering: JSON-RPC protocol compliance status, measured latency against SLA thresholds, presence and validity of OpenAPI schema, and correctness of HTTP 402 settlement headers — giving a pass/fail view of the target endpoint's readiness
Example use cases
Validate new MCP server before launch
“Before I go live, can you run a compliance audit on https://api.mymcp.dev/mcp and tell me if it passes JSON-RPC spec, has an OpenAPI schema, and handles HTTP 402 settlement headers correctly?”
Debug x402 payment header issues
“My x402 paywall endpoint at https://payments.myagent.io/v1/chat isn't being recognized by clients — can you audit it and check whether the HTTP 402 headers are set up to spec?”
SLA spot-check for production agent
“Can you do a latency and protocol compliance check on https://prod.agentservice.dev/a2a and report back on whether it's meeting SLA and is fully A2A compliant?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/paywall-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that an A2A, MCP, or x402-enabled service URL is protocol-compliant and production-ready — especially before integrating a third-party agent service, debugging payment header issues, or running SLA spot-checks on deployed agent infrastructure. It is purpose-built for agent protocol compliance auditing, not generic HTTP health checks or uptime monitoring.
Side effects
- Target URL is unreachable or times out — returns connectivity error
- Target URL returns non-JSON or malformed response — compliance check fails
- Missing or malformed HTTP 402 headers — flagged as non-compliant
- Target URL has no OpenAPI schema — schema check returns absent
- URL parameter not provided — returns validation error
