It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, all priced at $0.02 per request and settled in USDC on Base. No API keys or accounts are required — callers authenticate by attaching an x402 payment header with each request.\n\nThe specific endpoint `/api/v1/collections/46/floor` is not explicitly documented on the provider's landing page, which lists categories like Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure. However, the x402 challenge is live and returns a valid 402 response with an \"exact\" payment scheme requiring 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02). The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.\n\nDocumentation beyond the landing page is extremely thin — 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 example request/response payloads, and no description of the response schema for this particular endpoint. Callers should expect a JSON response (mimeType: application/json) but the exact fields are unknown.","tags":[],"capabilities":["nft-floor-price","x402-micropayment","usdc-payment","base-network","pay-per-request","no-api-key"],"categories":["nft","finance","web3"],"synonyms":["NFT floor price","collection floor price","NFT market data","x402 API","micropayment API","Base USDC API","NFT pricing"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The /collections/46/floor path is not listed among the provider's advertised APIs — it may be undocumented or experimental","All documentation pages (/docs, /pricing, /api, /README) render only a wallet-connect prompt with no technical content","Response schema is completely unknown; callers must discover fields empirically"],"endpointUrl":"https://lowpaymentfee.com/api/v1/collections/46/floor","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/collections/46/floor","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (valid 402 challenge captured) and pricing is clear ($0.02 USDC on Base).
