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 #36 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.
The specific endpoint `/api/v1/collections/36/floor` accepts POST requests and returns JSON. Based on the URL structure, it appears to serve NFT or digital-asset collection floor-price data, though the provider's landing page does not explicitly document this particular route — it is not listed among the advertised API categories. The x402 challenge confirms the endpoint is live, requires a payment of 20,000 base units of USDC (0.02 USD given 6 decimals) on Base mainnet, and responds with `application/json`.
No OpenAPI schema, detailed request/response documentation, or usage examples were found in the crawl. The docs, pricing, and API pages all rendered only a "Connect wallet" prompt with no additional content. Because of this, the exact request body format and response shape are unknown and must be discovered by the caller.
