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 ID 18 on the lowpaymentfee.com platform. 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 protocol for payment, settling in USDC on the Base network.
The specific endpoint `/api/v1/collections/18/floor` is not explicitly listed on the provider's landing page, but the x402 challenge confirms it is live and accepts POST requests. The payment challenge indicates a max amount of 20,000 base units of USDC (0x8335… on Base), which equals $0.02 given USDC's 6 decimals. This is consistent with the provider's advertised flat rate of $0.02 per request across all endpoints. No API keys or rate limits are required; access is granted immediately upon payment.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no usage examples available. The actual response format for this floor-price endpoint must be inferred. The endpoint is confirmed live (HTTP 402 challenge returned successfully).

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation, and no examples. The specific collection (ID 18) is not described anywhere. This is effectively a stub listing.
