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 utility services — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/160/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 accepts POST requests and returns application/json.\n\nThe platform's landing page advertises additional endpoints across categories like sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, and more — all at the same $0.02 price point. However, documentation beyond the landing page is extremely sparse: the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The actual data returned by this specific order-status endpoint is unknown beyond the MIME type (application/json).","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","USDC micropayment API","Base network API","pay-per-request API","lowpaymentfee","order tracking"],"warnings":["No OpenAPI or schema documentation available — request body and response format are entirely unknown.","The /docs, /pricing, /api, and /README pages all render only 'Connect wallet' with no usable content.","This endpoint is hardcoded to order ID 160; it is unclear whether other order IDs are supported or how to discover them.","The platform lists many other endpoints on its landing page but none have documented schemas or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/160/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/160/status","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base).
