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://hn-pulse.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 validity assessment, and HTTP 402 / x402 payment header correctness for the audited endpoint URL.
Example use cases
Pre-launch MCP server compliance check
“Before I ship my new MCP server, can you audit https://myapp.example.com/v1/mcp and confirm it's properly JSON-RPC compliant, has correct OpenAPI schema, and is ready for production traffic?”
x402 paywall header verification
“I set up an HTTP 402 paywall on my agent endpoint at https://api.myservice.dev/agent — can you verify that the x402 settlement headers are correctly configured and compliant with the IETF MPP spec?”
Agent SLA latency audit
“Can you run a compliance audit on https://partner-agent.example.com/a2a and tell me whether it meets latency SLA thresholds and if there are any protocol issues I should flag to the team?”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/x402-mpp-paywall-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that an A2A, MCP, or x402-enabled agent service is protocol-compliant before integrating it, deploying it, or listing it in an agent marketplace. It is especially useful when you need a single-call check covering JSON-RPC correctness, OpenAPI schema validity, HTTP 402 settlement headers, and latency SLA simultaneously, rather than running separate ad-hoc checks.
Side effects
- Target URL is unreachable or times out — audit cannot complete
- Target URL returns non-standard response format that cannot be parsed
- Invalid or malformed URL provided as input
- Target endpoint blocks probe requests (firewall, auth-required) — partial or no results
- x402 headers absent on target — reported as non-compliant rather than an error
