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/preflight/certify)
Output
Returns a structured compliance report indicating pass/fail status for JSON-RPC protocol conformance, observed latency vs SLA thresholds, OpenAPI schema validity, and HTTP 402 / x402 settlement header correctness for the submitted URL.
Example use cases
Pre-deploy agent endpoint certification
“Before I go live, can you certify https://staging.myagent.io/a2a for me — check its JSON-RPC compliance, latency SLA, OpenAPI schema, and x402 payment headers?”
Third-party MCP server due diligence
“I'm about to integrate a vendor's MCP server at https://tools.vendorapi.com/mcp — can you audit it for protocol compliance and tell me if the HTTP 402 settlement headers are set up correctly?”
Continuous compliance check for deployed x402 service
“Run a compliance check on https://payments.myservice.dev/v1/x402 and let me know if the HTTP 402 headers and JSON-RPC responses still conform to spec — I want to catch any drift before clients notice.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/preflight/certify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single-call compliance certification of an A2A, MCP, or x402 HTTP 402-capable URL covering JSON-RPC, latency SLA, OpenAPI schema, and payment header checks simultaneously — especially before deploying or integrating a new agent endpoint. Prefer this over manual testing or generic HTTP health checks when you need structured, protocol-specific audit results for agent-to-agent or model-context-protocol services.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- URL is missing or malformed — returns validation error on the url parameter
- Target server returns unexpected HTTP status codes unrelated to compliance — partial audit result
- Latency measurement may be affected by transient network conditions — SLA result could vary between calls
- Target endpoint blocks automated probes — incomplete audit data returned
