It is part of a broader platform that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/162/status` is labeled \"Premium API Access\" in the x402 challenge. The payment scheme is \"exact\" with a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 protocol's X-PAYMENT header, with no API keys or rate limits required. The endpoint responds with JSON.\n\nThe broader platform advertises endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, validation, and more — all at the same $0.02/request price point. However, documentation beyond the landing page is essentially empty (all subpages just show \"Connect wallet\"), so the actual behavior, request schemas, and response formats for this and other endpoints are undocumented.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC payment API","pay-per-call API","Base network API","lowpaymentfee"],"warnings":["All documentation pages (/docs, /api, /pricing, /README) return only 'Connect wallet' with no actual content.","Endpoint is hardcoded to order 162 — unclear if this is a demo or a real resource.","No OpenAPI spec or request/response schema available.","No example responses documented; actual output format is unknown.","The platform lists many other endpoints on its landing page, but none have documentation."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/162/status","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/orders/162/status","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing.
