How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
A JSON object containing the paid SKU identifier ('prooffilm'), a human-readable title ('Proof Film'), the price ('$0.25'), and a diagnostic note confirming the endpoint is live and payment was accepted. Unpaid requests receive HTTP 402 with EIP-3009 payment extras.
Example use cases
x402 client integration smoke test
“Hit the prooffilm paid endpoint to confirm my x402 client correctly attaches an EIP-3009 payment header, pays $0.25 USDC through OpenX402, and gets back the prooffilm JSON payload.”
Verify 402 gating before payment
“Can you try fetching the prooffilm diagnostic without payment first, so I can confirm the endpoint returns a proper HTTP 402 with eip3009 extras before I wire up my wallet?”
Validate OpenX402 facilitator settlement
“Use my OpenX402 facilitator to pay $0.25 USDC and fetch the prooffilm SKU response — I want to confirm end-to-end that the payment settles correctly and the JSON payload comes back with the right title and price fields.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/prooffilm?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate a live x402 payment flow end-to-end against a known, stable paid SKU. It is ideal for testing EIP-3009 authorization, confirming OpenX402 facilitator compatibility, or debugging x402 client implementations. Not suitable for production data retrieval — this is a diagnostics and integration-testing tool.
Side effects
- HTTP 402 returned when no valid payment header is provided — response includes eip3009 payment extras
- Payment rejected by OpenX402 facilitator if USDC authorization is invalid or insufficient
- Malformed EIP-3009 signature results in payment failure and 402 response
- Wrong facilitator used — only OpenX402 is accepted; other facilitators will not process payment
- Network timeout or service unavailability returns standard HTTP 5xx error
