NFT collection floor-price lookup via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns the floor price for NFT collection ID 15 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 data, and utility services. All endpoints use the x402 protocol on the Base network, settling in USDC at $0.02 per request with no API keys, rate limits, or subscriptions required.
The specific path `/api/v1/collections/15/floor` is not listed on the provider's landing page among the advertised API categories, but the x402 challenge is live and returns a valid 402 response with an "exact" payment scheme. The asset address `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` corresponds to USDC on Base (6 decimals), and the maxAmountRequired of 20000 base units equals $0.02. The endpoint accepts POST requests and returns application/json.
Documentation beyond the landing page is essentially empty — 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 example payloads available. The actual data source for NFT collection floor prices is unknown. Users should expect to experiment with the endpoint to discover the response format.
