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 #35 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/35/floor` accepts POST requests and returns JSON. Based on the URL pattern, it likely serves NFT or digital-asset collection floor-price data, though the provider does not publish detailed documentation for this particular route. The x402 challenge confirms the endpoint is live, requires a payment of 20,000 base units of USDC (0.02 USD given 6 decimals), and settles to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base.
The provider advertises no API keys, no rate limits, and instant access. Documentation pages beyond the landing page returned only a "Connect wallet" prompt with no further technical detail, so the request/response schema is not documented. The endpoint is discoverable and uses x402 version 1 with the "exact" payment scheme.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and documentation pages are empty stubs. The specific endpoint is not listed on the provider's landing page, so its exact behavior is inferred from the URL pattern only.
Warnings
- —No request or response schema documented; input/output format is unknown.
- —This specific endpoint (/api/v1/collections/35/floor) is not listed among the provider's advertised APIs on the landing page.
- —All documentation, pricing, API, and README pages return only a 'Connect wallet' prompt with no technical content.
- —The nature of 'collection 35' is unspecified; it is inferred to be an NFT collection from the URL pattern.
