NFT collection floor-price lookup via x402 micropayment on Base for $0.02/request
What it does
This endpoint at lowpaymentfee.com returns the floor price for NFT collection ID 41. It is part of a broader platform offering various pay-per-call APIs (data analytics, AI/ML, finance, crypto, infrastructure utilities) all settled via the x402 protocol on the Base network using USDC. Each request costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys, accounts, or rate limits are required — callers simply attach an x402 payment header to each POST request.
The specific endpoint `/api/v1/collections/41/floor` appears to serve NFT or digital-asset collection data, returning the current floor price for collection 41. The platform advertises itself under the tagline "Premium API Access" but the actual functionality is a straightforward per-call data endpoint. The x402 challenge confirms the endpoint is live, accepting payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response, and no description of what fields the response contains or what collection 41 refers to. The endpoint path suggests a RESTful collections API but specifics must be inferred.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, no examples, and the docs pages are empty. The specific collection (ID 41) and response format are entirely undocumented, making this effectively a stub listing.
Warnings

- —Docs, pricing, and API pages all render only 'Connect wallet' with no technical content
- —Collection 41 identity is not documented; unclear what asset or marketplace it refers to
- —No example responses available to verify data quality or format
