It is hosted on lowpaymentfee.com, a platform that offers a variety of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all settled on the Base network using USDC.\n\nThe specific endpoint `/api/v1/collections/44/floor` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds.\n\nDocumentation 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 schema, no example request/response payloads, and no description of what fields the floor-price response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response schema and collection identity (collection 44) are unknown.","tags":[],"capabilities":["nft-floor-price","x402-payment","usdc-micropayment","base-network","pay-per-request","json-api"],"categories":["finance","nft","web3"],"synonyms":["NFT floor price","collection floor price","NFT market data","x402 NFT API","micropayment API","Base USDC API","NFT pricing endpoint"],"warnings":["No API documentation available — docs, pricing, and README pages all render only 'Connect wallet' with no content.","No OpenAPI or output schema provided; response format is completely unknown.","Collection ID 44 is unidentified — no metadata about which NFT collection this covers.","No example requests or responses available anywhere in the crawl."],"endpointUrl":"https://lowpaymentfee.com/api/v1/collections/44/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/44/floor","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base).
