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://serp-extract.agentdiet.dev/v1/usdc-quote-audit)
Output
Returns a compliance audit report covering JSON-RPC protocol adherence, latency SLA pass/fail, OpenAPI schema validity, and HTTP 402 settlement header inspection for the submitted URL.
Example use cases
Pre-launch MCP server compliance check
“Before I go live, can you audit my MCP endpoint at https://tools.mycompany.dev/mcp and tell me if it's JSON-RPC compliant and meets latency SLA requirements?”
x402 payment header verification
“I've set up an HTTP 402 x402 USDC payment endpoint at https://api.myapp.io/v1/pay — can you check that it's returning the correct settlement headers and is properly configured?”
Third-party A2A agent vetting
“I want to integrate with an external A2A agent at https://partner-agent.thirdparty.com/a2a — can you run a full compliance audit on it to check JSON-RPC, OpenAPI schema, and SLA before I plug it into my workflow?”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/usdc-quote-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a remote A2A agent, MCP server, or HTTP 402 x402 payment endpoint is correctly implementing its protocol — especially before integrating it into an agent pipeline, publishing it to a marketplace, or trusting it with payment settlement. Prefer this over generic HTTP monitoring tools because it understands A2A, MCP, JSON-RPC, and x402 semantics specifically.
Side effects
- Target URL is unreachable or returns a network error — audit fails with connection error
- Target URL is not an A2A/MCP/x402 endpoint — audit returns low compliance scores or unexpected schema
- Malformed URL input — validation error returned
- Target endpoint returns non-standard HTTP codes that cannot be interpreted — partial audit result
- Timeout on slow target endpoints — latency SLA flagged as failed
