NFT collection floor-price endpoint, pay-per-call via x402 on Base (USDC).
What it does
This endpoint at lowpaymentfee.com returns the floor price for NFT collection ID 8. It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all gated via the x402 payment protocol on the Base network using USDC.
The specific endpoint `/api/v1/collections/8/floor` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform's landing page confirms uniform $0.02/request pricing across all endpoints, with no API keys, no rate limits, and no minimum commitments required.
Note that while the platform lists many endpoint categories (analytics, AI, finance, infrastructure), this specific listing covers only the collection floor-price endpoint. Documentation beyond the landing page is essentially empty — the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is live and returning a valid 402 challenge, but the lack of documentation makes it difficult to know the exact request body format or response structure.
