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 24. 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 to each POST request.
The x402 challenge confirms the endpoint is live, accepting payments of up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02) per call. The payment is sent to address 0x1A2B…85F3 with a 300-second timeout. The response MIME type is application/json.
The provider's landing page lists many other endpoints spanning data/analytics, AI/ML (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all at the same $0.02 price point. However, documentation beyond the landing page is essentially empty (all sub-pages only show a "Connect wallet" prompt), so there is no schema documentation, example responses, or detailed parameter descriptions available for this or any other endpoint on the platform.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is zero documentation for this specific endpoint — no request/response schema, no example payloads, and no description of what collection 24 is. All doc pages return only 'Connect wallet'. The listing is effectively a stub.
Warnings
- —No documentation available — all doc/pricing/API pages return only 'Connect wallet' with no content.
- —No request or response schema provided; the actual shape of the floor-price response is unknown.
- —Collection ID 24 is opaque — there is no indication of which NFT collection this refers to.
- —The broader platform lists many endpoints but none appear to have public documentation.
