NFT collection floor-price data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns floor-price data for NFT collection ID 12. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, all settled via the x402 protocol on the Base network using USDC. The specific endpoint path `/api/v1/collections/12/floor` suggests it serves NFT or digital-asset collection floor-price information, though the provider's landing page categorizes its offerings broadly under Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure.
Payment is handled inline: callers send an `X-PAYMENT` header containing a signed USDC payment on Base. The x402 challenge confirms the maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. There are no API keys, no rate limits, and no subscription commitments — each call is independently paid. The asset address `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` is the canonical USDC contract on Base mainnet.
Documentation is extremely sparse. The landing page lists many endpoints but provides no request/response schemas, parameter descriptions, or example payloads. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. Because of this, the exact request body format and response structure for the floor-price endpoint are unknown and must be discovered by the caller.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation, no request/response schema, no examples, and the endpoint path (collections/12/floor) is not mentioned anywhere on the provider's landing page. The actual data returned is entirely unknown.
Warnings
- —No request or response schema available — callers must discover the format experimentally.
- —The specific endpoint path /api/v1/collections/12/floor is not listed on the provider's landing page; it may be an unlisted or demo route.
- —All documentation pages (docs, pricing, API, README) render only a 'Connect wallet' prompt with no usable content.
- —The nature of 'collection 12' is unspecified — it is unclear what NFT collection or dataset this refers to.
