The provider operates a broad suite 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. No API keys or rate limits are required; callers simply attach an x402 payment header to each request.\n\nThe specific endpoint probed — `/api/v1/orders/42/status` — is listed under the provider's umbrella as \"Premium API Access.\" The x402 challenge confirms it is live, accepting POST requests, and requires a maximum of 20,000 base units of USDC (0.02 USDC, i.e., $0.02) per call. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the \"exact\" scheme with a 300-second timeout. The response MIME type is `application/json`.\n\nNote that the crawled documentation pages (docs, api, pricing, README) all returned only a \"Connect wallet\" prompt with no substantive content, so details about request/response schemas, order data fields, and error handling are unknown. The provider's landing page lists many other endpoints but does not provide detailed documentation for any of them. Treat this listing as a stub with confirmed liveness but sparse documentation.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key","json-response"],"categories":["commerce","data"],"synonyms":["order tracking","order status check","x402 API","micropayment API","Base USDC API","pay-per-request","lowpaymentfee"],"warnings":["No API documentation available — all doc pages return only 'Connect wallet'","The endpoint /api/v1/orders/42/status is not listed among the provider's advertised APIs; it may be a demo or placeholder","Request body schema and response body schema are completely unknown","No examples of successful responses are available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/42/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/42/status","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
