NFT collection floor-price lookup via x402 micropayment on Base (USDC).
What it does
This endpoint at lowpaymentfee.com returns the floor price for NFT collection ID 23. It is part of a broader platform offering pay-per-call APIs across data analytics, AI/ML, finance/Web3, and infrastructure categories, all settled via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/collections/23/floor` accepts POST requests and returns JSON. Payment is handled inline via the x402 header mechanism: each call costs up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) on Base, paid to the provider's wallet. No API keys or rate limits are advertised — access is gated purely by micropayment.
Documentation is extremely sparse. The landing page lists many endpoints but provides no request/response schemas, parameter descriptions, or usage examples. The /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no substantive content. The endpoint path suggests it retrieves floor-price data for a specific collection (ID 23), but there is no documentation confirming what collection this refers to or what fields the response contains.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC per call on Base). However, there is no documentation, no request/response schema, no examples, and no indication of what collection ID 23 refers to. The docs pages are all empty wallet-connect stubs.
Warnings
- —No API documentation available — all doc pages return only a wallet-connect prompt
- —No request or response schema provided; response format is unknown
- —Collection ID 23 is not identified — unclear what NFT collection this covers
- —The broader platform lists many endpoints but none appear documented beyond a title and price
