How this service works
Buyer-first MCP procurement gateway that discovers, compares and routes live x402 APIs without making the buyer choose a provider.
Output
Returns a structured JSON result containing: a numeric score (0-100) for the endpoint's x402 readiness, individual check results for OpenAPI validity, HTTP status, x-payment-info headers, and live GET probe (if requested), a safety summary confirming no funds were moved and no payment was signed, and a human-readable verdict such as 'metadata_ready'. Also includes timestamps and product/service attribution.
Example use cases
Pre-integration safety check for agent
“Before my agent starts calling https://payments.myservice.com/api/transcribe, can you verify it's a legitimate x402 endpoint with valid metadata and OpenAPI docs, and confirm it's safe to integrate?”
Marketplace listing quality audit
“I'm listing x402 endpoints in my AI agent marketplace — can you run a verification check on https://api.toolvendor.io/summarize to score its readiness and flag any missing payment documentation?”
Debugging misconfigured x402 endpoint
“My x402 endpoint at https://myapp.vercel.app/api/generate isn't being recognized by agent clients — can you verify it and tell me exactly which metadata or OpenAPI checks are failing?”
Technical details
Endpoint
POSThttps://kevaremesh-web.vercel.app/api/x402/x402-endpoint-verification-cdp-x402-endpoint-verification?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to pre-screen or audit any x402-protocol endpoint before your agent integrates or pays for it. It is the right choice when you want a zero-risk safety check (no payment signed, no funds moved) that validates OpenAPI compliance, payment metadata, and endpoint liveness. Prefer it over manual inspection when building agent marketplaces, automated capability registries, or CI pipelines that gatekeep x402 endpoints.
Side effects
- Unreachable URL returns failed metadata check with no score
- Endpoint missing x-payment-info header causes openapi.has_x_payment_info=false
- Non-x402 endpoints may return low scores or invalid verdict
- Private/local network URLs are blocked by safety rules
- Malformed OpenAPI docs result in openapi.valid=false
- Probe GET disabled by default; endpoints requiring it for full verification may show incomplete results
