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://x402-audit.agentdiet.dev/v1/preflight/certify)
Output
Returns a compliance certification report indicating whether the target URL passes JSON-RPC protocol compliance, latency SLA thresholds, OpenAPI schema validity, and correct HTTP 402 payment settlement header configuration, along with any specific failures or warnings.
Example use cases
Pre-deployment MCP server certification
“Before I go live, audit https://tools.myplatform.ai/mcp and tell me if it's fully compliant — JSON-RPC spec, latency SLA, OpenAPI schema, and HTTP 402 headers.”
Verifying x402 payment header setup
“I just added x402 payment support to my agent at https://api.mybot.dev/v1/agent — can you certify that the HTTP 402 settlement headers are correctly configured?”
Third-party agent due diligence
“I'm about to integrate with a vendor's A2A endpoint at https://partner-agent.acme.com/a2a — can you audit it for protocol compliance and latency SLA before I sign off?”
Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/preflight/certify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific A2A agent, MCP server, or x402-enabled service URL meets protocol compliance standards before integration or deployment, especially when HTTP 402 payment header correctness is a concern. Prefer this over generic HTTP probing tools when you need structured compliance output covering JSON-RPC, OpenAPI schema, latency SLA, and x402 payment headers in a single call.
Side effects
- Target URL is unreachable or returns a network error — audit fails with connectivity error
- Target URL does not expose a valid JSON-RPC or OpenAPI interface — schema validation fails
- Target URL has no HTTP 402 headers — payment compliance check fails
- Target URL responds too slowly — latency SLA check fails
- Invalid or malformed URL provided as input — request rejected with validation error
