What it does

This endpoint returns floor-price data for NFT collection ID 46 via the x402 payment protocol on the Base network. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, all priced at $0.02 per request and settled in USDC on Base. No API keys or accounts are required — callers authenticate by attaching an x402 payment header with each request.

The specific endpoint `/api/v1/collections/46/floor` is not explicitly documented on the provider's landing page, which lists categories like Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure. However, the x402 challenge is live and returns a valid 402 response with an "exact" payment scheme requiring 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02). The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.

Documentation beyond the landing page is extremely thin — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema for this particular endpoint. Callers should expect a JSON response (mimeType: application/json) but the exact fields are unknown.

Quality

0.35/ 1.00

The endpoint is live (valid 402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no examples, and the specific collections/floor endpoint is not mentioned on the provider's own landing page. Documentation pages are effectively empty.

Warnings

  • —The /collections/46/floor path is not listed among the provider's advertised APIs — it may be undocumented or experimental
  • —All documentation pages (/docs, /pricing, /api, /README) render only a wallet-connect prompt with no technical content
