What it does

This endpoint at lowpaymentfee.com returns floor-price data for NFT collection ID 30. It is part of a broader suite of x402-enabled APIs offered by the same provider, spanning data analytics, AI/ML inference, finance/Web3, and utility services. All endpoints share a uniform $0.02-per-request pricing model settled in USDC on the Base network.

The specific endpoint `/api/v1/collections/30/floor` accepts POST requests and is gated by the x402 payment protocol (version 1). The payment challenge requires up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) sent to the provider's wallet on Base. No API keys or rate limits are advertised; access is granted per-request upon valid payment. The response MIME type is `application/json`.

Documentation beyond the landing page is sparse — 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 request/response schema documentation, and no example payloads available. The endpoint is confirmed live (402 challenge captured), but the actual response structure and the meaning of "collection 30" are not documented.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no examples, and the docs pages are empty. The purpose of 'collection 30' is undocumented. This is effectively a stub listing.

Warnings

  • No OpenAPI or schema documentation available — response format is unknown.
  • All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content.
  • The meaning of 'collections/30' (which NFT collection) is not documented anywhere.
  • No request body schema or example response is available; callers must discover behavior empirically.
