NFT collection floor-price lookup via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns the floor price for NFT collection ID 38. It is part of a broader platform offering pay-per-call APIs across data analytics, AI/ML, finance/Web3, and utility categories, all settled via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/collections/38/floor` accepts POST requests and is gated by an x402 payment challenge. The maximum amount required is 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 USD (USDC uses 6 decimals). Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds. No API keys or rate limits are advertised; access is instant once payment is included in the X-PAYMENT header.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no response examples, and no description of what fields the floor-price response contains. The endpoint is confirmed live (returns 402 with a valid x402 challenge), but the actual response payload structure is unknown.
