How this service works
Live conformance check of an x402 endpoint (Solana or Base) before you pay it
Output
A live conformance report indicating whether the target x402 endpoint correctly implements the x402 protocol, including payment header requirements for Solana or Base chains, and any detected misconfigurations or non-conformances.
Example use cases
Pre-payment API validation for agent
“I'm about to call an x402-gated API at https://payments.example.com/inference and I don't want to waste USDC if it's misconfigured — can you do a conformance check on it with a POST probe first?”
Debugging a broken x402 integration
“My x402 endpoint at https://myapp.io/api/generate isn't accepting payments and I'm not sure why — can you probe it with a GET request and tell me whether it's actually x402 conformant?”
Auditing a third-party pay-per-use API
“I found this x402 API at https://third-party-service.xyz/api/summarize that claims to support Base payments — can you verify it's actually conformant before I integrate it into my workflow?”
Technical details
Endpoint
POSThttps://coppice-ai.com/api/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify an x402-gated API is correctly implemented before committing a payment, especially when integrating a new third-party x402 service, debugging payment failures, or auditing whether a claimed x402 endpoint is genuinely conformant on Solana or Base. Prefer this over manually inspecting HTTP headers or guessing at conformance.
Side effects
- Target endpoint is unreachable or returns a non-402 response unexpectedly
- Target endpoint is not an x402 endpoint at all (returns 200 or other non-payment status)
- Unsupported chain — endpoint uses a chain other than Solana or Base
- Malformed URL input causes request to fail
- Target endpoint has rate limiting that blocks the probe
- Network timeout when probing the target URL
