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/57/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 (mimeType: application/json) and supports POST.\n\nThe broader platform advertises endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation — all at the same $0.02 price point. However, documentation pages (/docs, /pricing, /api, /README) returned only a \"Connect wallet\" prompt with no substantive content, so the actual behavior and response schemas of these endpoints remain undocumented.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","json-response","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","pay-per-call API","USDC payment API","Base network API","lowpaymentfee"],"warnings":["Endpoint URL is hardcoded to order ID 57 — unclear if this is parameterizable or a demo artifact","All documentation pages (/docs, /pricing, /api, /README) returned no substantive content","No response schema or example response available","No OpenAPI specification found","The platform lists many other endpoints but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/57/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/57/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 (402 challenge captured) and pricing is clear ($0.02 USDC on Base).
