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/159/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 (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, which has 6 decimals), equating to $0.02 per call. Payment is made via the X-PAYMENT header using the x402 protocol (version 1). No API keys, rate limits, or subscriptions are required — callers simply attach a valid payment proof to each request.\n\nThe platform's landing page advertises additional endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, and more, all at the same $0.02 price point. However, the crawled documentation pages (docs, pricing, README) returned only a \"Connect wallet\" prompt with no further technical detail, so the exact request/response schemas for this order-status endpoint are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","pay-per-call API","USDC payment API","Base network API","lowpaymentfee"],"warnings":["Documentation pages (/docs, /pricing, /README) return no useful content beyond 'Connect wallet'","No request body schema or response schema available — callers must guess at the payload format","Endpoint is hardcoded to order ID 159; unclear if other order IDs are supported via different URLs","The platform lists many other endpoints on its landing page but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/159/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/159/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), but there is no OpenAPI schema, no request/response examples, and documentation pages are empty stubs.
