NFT collection floor-price lookup via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns floor-price data for NFT collection ID 10. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, all settled via the x402 protocol on the Base network using USDC. The specific endpoint path `/api/v1/collections/10/floor` suggests it serves NFT or digital-asset collection floor prices, though the provider's landing page categorizes its Finance & Web3 APIs under price feeds, token quotes, and similar headings.
Payment is handled inline: callers receive a 402 challenge requiring an `X-PAYMENT` header with an exact-scheme USDC payment of up to 20,000 base units (i.e., $0.02 given USDC's 6 decimals) sent to the provider's address on Base. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-request. The response MIME type is `application/json`.
Documentation is extremely thin. The landing page lists many endpoints but provides no request/response schemas, parameter descriptions, or example payloads. The `/docs`, `/api`, `/pricing`, and `/README` pages all render only a "Connect wallet" prompt with no additional content. Because of this, the exact request body format and response structure for this endpoint are unknown and must be discovered experimentally.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, no examples, and the docs pages are empty. The specific collection ID 10 is hard-coded in the path with no explanation of what collection it refers to.
Warnings
- —No API documentation available — /docs, /api, /pricing, and /README all return only a wallet-connect prompt with no content.
- —No request or response schema provided; callers must discover the payload format experimentally.
- —The endpoint path references collection ID 10 but no information is given about what collection this represents.
- —The landing page lists many endpoint categories but this specific /collections/10/floor path is not listed among them, raising questions about its status.
