The specific endpoint `/api/v1/wire/72` accepts POST requests and charges 20,000 base units of USDC (USD Coin, 6 decimals) on the Base network, which equals $0.02 per request. Payment is handled inline via the X-PAYMENT header with no API keys or rate limits required.\n\nThe broader lowpaymentfee.com platform offers a suite of pay-per-call APIs spanning 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 are priced uniformly at $0.02 per request and settle on the Base network using USDC.\n\nThe specific functionality behind `/api/v1/wire/72` is not documented beyond the generic label \"Premium API Access.\" There is no OpenAPI schema, no request/response examples, and the docs pages only show a wallet-connect prompt. The endpoint is confirmed live (returns a valid 402 challenge), but what data or service it actually returns upon successful payment is unclear.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-call","no-api-key","post-method"],"categories":["api-marketplace","crypto"],"synonyms":["pay-per-request API","x402 endpoint","USDC micropayment API","Base network API","lowpaymentfee","crypto-paid API","402 payment protocol"],"warnings":["No documentation available for what /api/v1/wire/72 actually does or returns","No OpenAPI schema or request/response examples provided","Docs, pricing, and README pages all render only a wallet-connect prompt with no useful content","The label 'Premium API Access' is generic and does not describe functionality"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wire/72","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/wire/72","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid 402 challenge, but there is no documentation of what the endpoint actually returns, no request/response schema, and the docs pages are empty beyond a wallet-connect prompt.
