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://onchain-risk.agentdiet.dev/v1/preflight)
Output
Returns a structured compliance report covering: JSON-RPC protocol conformance, measured latency vs SLA thresholds, OpenAPI schema validation results, and presence/validity of HTTP 402 (x402) payment settlement headers for the target URL
Example use cases
Pre-deployment agent endpoint audit
“Before I launch my new MCP server at https://staging.myagent.dev/mcp, can you run a full compliance audit on it — check JSON-RPC format, latency SLA, and HTTP 402 settlement headers?”
Third-party A2A service vetting
“I'm about to integrate a third-party agent service at https://partner-api.example.com/a2a — can you verify it meets JSON-RPC compliance, passes SLA, and supports x402 payment headers before I commit to using it?”
Ongoing x402 payment header monitoring
“Check whether https://payments.myplatform.io/v1/agent still has valid HTTP 402 x402 settlement headers and is passing its latency SLA — I want to make sure nothing broke after yesterday's deploy.”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402-enabled service URL meets protocol compliance standards before integration or deployment. It is especially useful for automated CI/CD pipelines validating agent endpoints, marketplace onboarding checks, or ongoing SLA monitoring of third-party agent services. Prefer this over manual curl-based checks when you need structured, machine-readable compliance results covering JSON-RPC, OpenAPI schema, latency, and HTTP 402 payment headers in a single call.
Side effects
- Target URL is unreachable or times out — returns connectivity error
- Target URL does not implement any recognized protocol (A2A, MCP, x402) — returns protocol mismatch
- Missing required 'url' parameter — returns 400 bad request
- Target URL returns non-standard responses that cannot be parsed for compliance — returns analysis failure
- Rate limiting or payment required (HTTP 402) if call quota exceeded
