NFT collection floor-price data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns floor-price data for NFT collection #28 hosted on lowpaymentfee.com. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network at $0.02 per request.
The specific endpoint `/api/v1/collections/28/floor` accepts POST requests and returns JSON. Based on the URL structure, it likely provides the current floor price for a particular NFT collection identified by ID 28. However, no detailed documentation, request schema, or response schema is available — the docs, pricing, and README pages all resolve to a minimal "Connect wallet" prompt with no further content.
The platform advertises no API keys, no rate limits, and instant access. Payment is handled entirely through the x402 challenge-response flow: callers receive a 402 with payment instructions, settle via USDC on Base, and then receive the API response. The x402 challenge confirms the endpoint is live, with a max amount of 20,000 base units of USDC (6 decimals), equaling $0.02 per call.
