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://whale-momentum.agentdiet.dev/v1/paywall-check)
Output
Returns a structured audit report covering JSON-RPC protocol compliance, measured latency vs SLA thresholds, OpenAPI schema validity, and HTTP 402/x402 settlement header correctness for the submitted URL.
Example use cases
Pre-launch agent endpoint compliance check
“Before I go live, can you run a full compliance audit on my A2A endpoint at https://staging.myservice.ai/agent — I need to know if the JSON-RPC responses are valid, the latency is within SLA, and the HTTP 402 headers are set up correctly?”
Verifying third-party MCP server integrity
“I'm about to integrate a third-party MCP tool at https://tools.partnerapi.io/v1/mcp into my agent stack — can you audit it for protocol compliance and check if its OpenAPI schema and x402 paywall headers are properly implemented?”
Ongoing x402 paywall health check
“Can you check whether my x402 payment endpoint at https://whale-momentum.agentdiet.dev/v1/paywall-check is correctly returning settlement headers and passing the IETF MPP compliance requirements?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/paywall-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402 paywall URL is correctly implementing its declared protocols — especially before integration, after deployment, or as a periodic compliance health check. It is more appropriate than generic HTTP testing tools when you specifically need JSON-RPC, OpenAPI, SLA latency, and HTTP 402 settlement header validation in a single call.
Side effects
- Target URL is unreachable or returns a network error
- Target URL does not implement any auditable protocol (not A2A, MCP, or x402)
- Malformed or missing URL query parameter returns a 400 error
- Target service times out, resulting in an SLA failure report
- OpenAPI schema cannot be fetched or parsed from the target
