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 17. 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/17/floor` accepts POST requests and returns JSON. Payment is handled inline via the x402 `exact` scheme: each call costs up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) sent to the provider's address on Base. No API keys or accounts are required — callers attach an `X-PAYMENT` header with a valid x402 payment proof and receive the response immediately.
The platform advertises uniform $0.02 pricing across all endpoints, no rate limits, and no minimum commitments. Documentation pages (docs, pricing, README) were largely empty at crawl time, showing only a "Connect wallet" prompt, so detailed request/response schemas and field definitions are unavailable. The endpoint is confirmed live (402 challenge captured).

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and all docs pages returned only a wallet-connect prompt. The specific data returned by this floor-price endpoint is entirely undocumented.
Warnings
- —No request or response schema documented — callers must discover the format experimentally.
- —Documentation pages (/docs, /pricing, /README) are effectively empty, showing only 'Connect wallet'.
- —The endpoint path references a hardcoded collection ID (17); it is unclear what collection this maps to or whether other IDs are valid.
- —No information on data freshness, update frequency, or data source for floor prices.
