What it does

This endpoint at lowpaymentfee.com returns the floor price for NFT collection ID 6. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, all priced at $0.02 per request and settled in USDC on the Base network via the x402 protocol. No API keys or accounts are required — callers simply attach an x402 payment header with each request.

The specific endpoint `/api/v1/collections/6/floor` accepts POST requests and returns JSON. Based on the URL structure, it appears to serve floor-price data for a particular NFT or token collection (collection ID 6). The provider's site groups this under "Finance & Web3" alongside price feeds, exchange rates, token quotes, and gas estimates, though this specific collections endpoint is not explicitly listed on the landing page.

The x402 challenge confirms the endpoint is live, accepting USDC payments (contract 0x8335…2913 on Base) with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The payment recipient is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. Timeout is 300 seconds. No OpenAPI schema, detailed documentation, or example responses were found in the crawl.

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no example payloads, and the specific collections endpoint is not listed on the provider's landing page. The docs, pricing, and API pages all returned only a 'Connect wallet' stub with no useful content.
