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://preflight.agentdiet.dev/v1/402-compliance)
Output
Returns a compliance audit report covering JSON-RPC protocol adherence, measured latency vs SLA thresholds, OpenAPI schema validity, and HTTP 402 payment settlement header inspection for the provided URL.
Example use cases
Pre-launch MCP server compliance check
“Before I go live, can you audit my MCP server at https://tools.myapp.dev/mcp to make sure it's JSON-RPC compliant and has the right HTTP 402 settlement headers?”
Third-party A2A tool vetting
“I want to integrate this A2A tool at https://partner.agentplatform.io/v1/agent into my workflow — can you check whether it meets SLA requirements and passes protocol compliance?”
x402 payment endpoint verification
“Can you verify that https://api.myservice.dev/v1/402-endpoint correctly implements the x402 v2 HTTP 402 payment headers and responds within acceptable latency?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/402-compliance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402-enabled HTTP service conforms to protocol standards including JSON-RPC, OpenAPI schemas, HTTP 402 payment headers, and latency SLAs — especially before integrating a third-party agent tool or deploying your own.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- Malformed or missing URL parameter — returns 400 bad request
- Target URL does not implement any auditable protocol — returns partial or empty compliance results
- Non-HTTP URL scheme — may be rejected
- Rate limit or payment failure at $0.01 per call — returns 402 or 429
