NFT collection floor-price data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns floor-price data for NFT collection #34 via the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility endpoints — all gated behind x402 micropayments settled in USDC on the Base network.
The specific resource at `/api/v1/collections/34/floor` accepts POST requests and returns JSON. Each call costs a maximum of 0.02 USDC (20,000 base units of USDC with 6 decimals). Payment is made inline via the x402 `X-PAYMENT` header — no API keys, accounts, or rate limits are required. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout window.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of what collection #34 actually is or what fields the response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to assess data quality or response schema.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no examples, and no information about what collection #34 represents. Documentation pages are effectively empty. This is a stub-level listing.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All documentation pages (/docs, /api, /pricing, /README) return only a 'Connect wallet' prompt with no content
- —Collection #34 is not identified — unclear what NFT collection this floor price refers to
- —No example responses available to verify data quality or structure
- —The broader platform lists many endpoints (AI, analytics, finance, etc.) all at $0.02 — unclear whether all are fully functional or placeholders
