What it does

This endpoint at lowpaymentfee.com returns floor-price data for NFT collection ID 31. 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, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network at $0.02 per request.

The specific endpoint `/api/v1/collections/31/floor` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a max amount of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the `exact` scheme to the provider's wallet. No API keys or rate limits are advertised; access is gated purely by the x402 micropayment.

Documentation is extremely sparse. The provider's docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint path suggests it returns floor-price information for a specific NFT collection, but the exact response format and any accepted request parameters are unknown.

Quality

0.35/ 1.00

The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no examples, and all documentation pages are empty beyond a wallet-connect prompt. The endpoint's exact behavior must be inferred from its URL path alone.

Warnings

  • —No OpenAPI or schema documentation available — request parameters and response format are unknown
  • —All doc/pricing/README pages render only 'Connect wallet' with no technical content
  • —The specific collection ID 31 is hardcoded in the path; it is unclear what collection this refers to or whether other collection IDs are supported
  • —No rate-limit or SLA information provided
