NFT collection floor price data via x402 micropayment on Base network, $0.02/request.
What it does
This endpoint provides NFT collection floor price data at the path `/api/v1/collections/25/floor`. It is part of a broader suite of pay-per-request APIs hosted on lowpaymentfee.com, all settled via the x402 protocol on the Base network using USDC. The specific endpoint returns JSON data about the floor price of collection ID 25.
The provider operates a multi-category API platform covering data & analytics, AI/ML inference, finance & Web3, and infrastructure utilities—all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payment is handled inline via the x402 payment header using USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).
Documentation is extremely sparse—the docs, pricing, and API pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response documentation, and no description of what fields the floor price response contains. The endpoint is confirmed live (returns 402 challenge) and accepts POST requests.

Quality
The endpoint is confirmed live with a valid 402 challenge, but documentation is essentially nonexistent—no schema, no example responses, no description of what 'collection 25' is. The specific endpoint path (collections/25/floor) is not even listed on the provider's homepage, making it unclear what data is actually returned.
Warnings

- —The specific endpoint /api/v1/collections/25/floor is not listed among the provider's advertised APIs on the homepage
