It is part of a broader platform (lowpaymentfee.com) that offers a variety of API endpoints across data analytics, AI/ML inference, finance/Web3, 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/52/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. Payment is made via the X-PAYMENT header per the x402 protocol. There are no API keys, no rate limits, and no subscription commitments — each call is independently paid.\n\nThe broader platform advertises endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, validation, conversion, and more, all at the same $0.02 price point. However, no OpenAPI schema, detailed documentation, or example request/response payloads were found in the crawl. The docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","micropayment","pay-per-request","no-api-key","no-rate-limit"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","micropayment API","USDC payment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No OpenAPI or detailed API documentation available — docs/pricing/README pages are empty stubs","Endpoint path is hardcoded to order 52; unclear if other order IDs are supported or how to discover them","No request body schema or response schema documented anywhere","The 'Premium API Access' description is generic and does not explain what data is returned"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/52/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/52/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 confirmed) and pricing is clear ($0.02 USDC on Base).
