NFT collection floor-price lookup via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns floor-price data for NFT collection ID 2. 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/2/floor` accepts POST requests and returns JSON. Based on the URL structure, it likely returns the current floor price for a specific NFT or token collection. The provider's site also lists endpoints for analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance (price feeds, exchange rates, token quotes, gas estimates), and utility services (geocoding, validation, conversion, generation), all at the same $0.02 price point.
The x402 challenge confirms the endpoint is live, accepting payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` in USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The maximum amount required is 20,000 base units, which equals $0.02 (USDC uses 6 decimals). No OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content.

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 schema, no documented request/response format, no example payloads, and the docs pages are empty. The specific purpose of 'collections/2/floor' is inferred from the URL path only.
Warnings
