The specific resource `/api/v1/nfts/96` is labeled \"Premium API Access\" and is gated behind an x402 payment challenge requiring USDC on the Base network. The maximum amount required per call is 20,000 base units of USDC (0.02 USD, i.e., two cents), consistent with the site-wide pricing of $0.02 per request.\n\nThe broader lowpaymentfee.com platform advertises a range of API categories including Data & Analytics (metrics, reports, data export, insights), AI & Machine Learning (sentiment analysis, text summarization, classification, embeddings), Finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and Infrastructure utilities (geocoding, validation, conversion, generation). All endpoints share the same $0.02/request pricing model with no API keys, no rate limits, and no minimum commitments. Payments settle in USDC on the Base L2 network.\n\nThe specific functionality behind `/api/v1/nfts/96` is not documented beyond the generic \"Premium API Access\" label. There is no OpenAPI schema, no detailed documentation, and no example request/response payloads available from the crawled pages. The endpoint accepts POST requests and returns `application/json`. Without further documentation it is unclear what input the endpoint expects or what data it returns — the NFT-related path suggests it may serve NFT metadata or related information, but this is speculative.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","nft-data","json-api"],"categories":["web3","nft"],"synonyms":["NFT API","premium API access","x402 NFT endpoint","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No documentation available for the /api/v1/nfts/96 endpoint — actual functionality is unknown","No OpenAPI or schema definition found","No example request or response payloads available","The purpose of this specific NFT endpoint is unclear; 'Premium API Access' is a generic label applied across the platform","Most crawled subpages returned no meaningful content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/nfts/96","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/nfts/96","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base).
