How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object containing the SKU identifier ('amountfloor'), the human-readable title ('Amount Floor'), the price ('$0.02'), and a diagnostic note clarifying the response is an example paid JSON shape, not a live settlement.
Example use cases
Pre-flight x402 payment check
“Before I try to call that paid API, can you check what the minimum atomic floor amount is set to for https://example.com/api/v1/data so I know how much USDC to authorize?”
Facilitator indexing floor audit
“I'm indexing x402 endpoints for my facilitator — can you look up the amount floor for the origin https://myservice.com using an atomic floor of 500?”
Debugging 402 payment rejection
“I keep getting 402 errors when calling https://openclawproductions.com/api/v1/amountfloor — can you pull the diagnostic amount floor info for that URL so I can figure out what payment amount I need?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/amountfloor?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine the minimum atomic payment floor for an x402-gated URL, particularly when working with the OpenX402 facilitator. It is ideal for pre-flight diagnostics before attempting a paid API call, for facilitator indexing tasks, or for debugging HTTP 402 payment rejections where the floor amount is unclear.
Side effects

- Invalid or unreachable URL parameter returns an error
- Non-OpenX402 facilitator usage is not supported and may be rejected
- Malformed query parameters may result in validation errors
- GET/HEAD/DELETE are supported; other HTTP methods are rejected
