NFT collection floor-price data 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 45. 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/45/floor` suggests it serves NFT or digital-asset collection floor prices, though the provider's landing page categorizes its offerings under Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure.
Pricing is $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled inline via the x402 `exact` scheme — no API keys, no subscriptions, no rate limits. The endpoint accepts POST requests and returns `application/json`. The x402 challenge is live and well-formed, advertising payment to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base with a 300-second timeout.
Documentation is extremely thin: the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawl. The exact request body format and response structure for this specific collection-floor endpoint are unknown and must be discovered by the caller.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no request/response schema, and no examples. The specific endpoint path (collections/45/floor) is not mentioned on the landing page, and all doc pages return only a wallet-connect prompt. Effectively a stub listing.
