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://defi-yield.agentdiet.dev/v1/preflight)
Output
Returns a structured compliance report covering JSON-RPC protocol conformance, measured latency against SLA thresholds, OpenAPI schema validity findings, and HTTP 402 / x402 settlement header presence and correctness for the audited URL.
Example use cases
Pre-deployment MCP server compliance check
“Before I go live, can you audit https://staging.myagent.io/mcp and tell me whether it passes JSON-RPC spec, has a valid OpenAPI schema, and is correctly returning HTTP 402 x402 settlement headers?”
Third-party A2A vendor due diligence
“I'm evaluating a vendor's agent API at https://partner-agent.io/v1/a2a — can you run a full protocol compliance audit on it and report back on latency SLA, JSON-RPC validity, and x402 support?”
Debugging HTTP 402 payment header issues
“My agent at https://defi-yield.agentdiet.dev/v1/preflight should be returning HTTP 402 headers for x402 payment flow but clients are complaining — can you run a compliance audit on it and show me what's wrong with the settlement headers?”
Technical details
Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a remote A2A agent, MCP server, or x402-enabled service meets protocol standards before integration, deployment, or payment flow activation. It is specifically suited for auditing JSON-RPC compliance, HTTP 402 settlement header correctness, latency SLA, and OpenAPI schema validity in one call — prefer it over generic HTTP probing tools when the target is an AI agent or MCP endpoint.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- Target URL returns non-standard responses that cannot be parsed for compliance
- Missing or malformed 'url' query parameter returns a 400 validation error
- Target service blocks probe requests, resulting in incomplete audit data
- HTTP 402 headers absent at target leads to failed x402 compliance status
