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 name ('callbudget'), a human-readable title ('Call Budget'), the price ('$0.24'), and a diagnostic note confirming the paid response shape. Unpaid requests return HTTP 402 with EIP-3009 payment extras instead.
Example use cases
Validate x402 payment flow end-to-end
“I want to confirm my x402 EIP-3009 payment setup is working correctly — can you hit the callbudget diagnostic endpoint, pay the $0.24 USDC, and show me the full response?”
Inspect paid SKU response shape
“What does a successful paid x402 callbudget response actually look like? Send the payment and fetch the real JSON shape from the openclawproductions diagnostic endpoint.”
Debug HTTP 402 gating behavior
“I'm building an x402 integration and need to understand how the 402 error with EIP-3009 extras looks when I don't attach payment — can you probe the callbudget endpoint without paying first so I can see the unpaid rejection response?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/callbudget?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test or demonstrate x402 micropayment gating behavior with a real paid SKU, verify EIP-3009 payment authorization works correctly, or inspect what a legitimate paid x402 JSON response looks like. It is specifically suited for developers integrating x402 into their own APIs who want a live reference implementation requiring OpenX402 as facilitator.
Side effects
- HTTP 402 returned with EIP-3009 extras when no valid x402 payment header is attached
- Payment rejected if USDC authorization amount is below $0.24
- OpenX402 facilitator unavailable causes payment settlement failure
- Malformed EIP-3009 signature results in 402 or 401 rejection
- Rate limiting or repeated calls may be blocked by the facilitator
