It is part of a broader platform offering dozens of pay-per-call 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/147/status` is labeled \"Premium API Access\" and accepts POST requests. Payment is handled via the x402 exact-amount scheme: the caller includes an X-PAYMENT header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is directed to address `0x1A2B...85F3` on Base, with a timeout of 300 seconds. No API keys or rate limits are advertised; access is purely pay-per-use.\n\nThe platform's landing page lists additional endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, validation, and more — all at the same $0.02 price point. However, documentation beyond the landing page is essentially empty (pages like /docs, /pricing, and /README only show a \"Connect wallet\" prompt), so the actual response schemas and detailed behavior of each endpoint are undocumented. This specific endpoint's purpose — order status retrieval — is clear from the URL path but no response schema or example output is provided.","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"],"warnings":["No API documentation available — /docs, /pricing, and /README pages are empty beyond a wallet connect prompt","No response schema or example output provided for this endpoint","Endpoint path is hardcoded to order 147; unclear if other order IDs are supported or what the order represents","Platform appears to be a demo or early-stage project with many listed endpoints but no substantive documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/147/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/147/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).
