NFT collection floor-price data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns the floor price for NFT collection ID 13, hosted on lowpaymentfee.com. It is part of a broader suite of pay-per-call APIs covering data analytics, AI/ML inference, finance/Web3 data, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network at $0.02 per request.
The specific endpoint `/api/v1/collections/13/floor` accepts POST requests and returns JSON. Based on the URL structure, it likely serves NFT marketplace or collection data — specifically the floor price for a given collection. However, no detailed documentation, request/response schema, or examples are available from the crawled pages (docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content).
The endpoint is live and returns a valid x402 challenge (HTTP 402) with a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02. Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on the Base network. No API keys or rate limits are advertised; access is purely pay-per-call.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no request/response schema, and no examples available. The docs, pricing, and API pages are all empty beyond a wallet-connect prompt. The endpoint's purpose is inferred solely from its URL path. This is effectively a stub listing.
Warnings
- —No API documentation available — docs page only shows 'Connect wallet'
- —No request or response schema provided; endpoint behavior is inferred from URL path only
- —Collection ID 13 is hardcoded in the URL; unclear what collection it refers to
- —The broader platform lists many endpoints but none have documented schemas
