What it does

This endpoint at lowpaymentfee.com returns the floor price for NFT collection #42. It is part of a broader platform offering dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all settled via the x402 protocol on the Base network using USDC.

The specific endpoint `/api/v1/collections/42/floor` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform's landing page confirms a flat $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments required.

Note that while the platform lists many endpoint categories (analytics, AI, finance, infrastructure), this specific listing covers only the `/api/v1/collections/42/floor` path. No OpenAPI schema, detailed documentation, or example responses were available from the crawled pages — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no substantive content. The actual response format and fields returned by this endpoint are unknown.

Quality

0.35/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documentation, no example responses, and no description of what fields the response contains. The docs pages returned only wallet-connect prompts. This is effectively a stub listing.

Warnings

  • —No OpenAPI or response schema available — response format is unknown
  • —Documentation pages (/docs, /pricing, /api, /README) all returned only 'Connect wallet' with no content
  • —The endpoint path suggests collection ID 42 is hardcoded; it is unclear if other collection IDs are supported
  • —No examples of actual response data were found in any crawled material
