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 ID 40 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 on the platform use the x402 protocol for payment, settling in USDC on the Base network.
The specific endpoint `/api/v1/collections/40/floor` is not explicitly listed on the provider's landing page among the advertised API categories, but the x402 challenge is live and returns a valid 402 response. The payment required is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. The endpoint accepts POST requests and returns JSON.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the response contains or what parameters the request accepts. The collection ID 40 is hardcoded in the URL path, and it is unclear what collection it refers to or whether other collection IDs are available. Use with caution given the lack of documentation.
