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 SKU identifier ('ratelimitbook'), a diagnostic note clarifying this is an example paid response, the price ($0.25), and the product title ('Rate Limit Book'). Unpaid requests return HTTP 402 with EIP-3009 payment extras instead.
Example use cases
Verify x402 payment integration
“Can you hit the x402 ratelimitbook endpoint and confirm that paying 0.25 USDC via OpenX402 returns the expected paid JSON shape instead of a 402 error?”
Inspect EIP-3009 402 response details
“I need to see what HTTP 402 headers and EIP-3009 extras this rate limit book endpoint sends back when I haven't paid yet — can you fetch it unpaid and show me the response?”
Test micropayment-gated API in staging
“Run a diagnostic against the OpenX402 ratelimitbook SKU and show me the full JSON result after the USDC micropayment settles, so I can verify my x402 integration is wired up correctly.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/ratelimitbook?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or demonstrate the x402 HTTP micropayment protocol in action, specifically using the OpenX402 facilitator and USDC via EIP-3009. It is ideal for developers verifying their x402 client integration, inspecting 402 response payloads, or confirming that payment-gated API mechanics work end-to-end. Not suitable for production data retrieval or non-x402 payment contexts.
Side effects
- HTTP 402 returned if x402 payment has not been settled — includes EIP-3009 payment authorization details in response extras
- Payment processed by unsupported facilitator (only OpenX402 accepted) results in rejection
- Malformed or missing EIP-3009 authorization headers cause payment failure
- Network timeout or server unavailability returns standard HTTP error
