It is part of a broader platform (lowpaymentfee.com) that offers a variety 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.\n\nThe specific endpoint `/api/v1/orders/41/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 (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 given USDC's 6 decimals. No API keys or rate limits are advertised; access is granted per-call by including a valid X-PAYMENT header. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol.\n\nDocumentation on the site is extremely thin — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema beyond the x402 outputSchema stub, and no explanation of what the order status response actually contains. The endpoint path suggests it returns status information for a specific order (ID 41), but the broader utility or whether the order ID is parameterizable is unknown from available material.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","Base USDC API","pay-per-request","lowpaymentfee"],"warnings":["No OpenAPI or request/response schema available — actual response format is unknown.","Documentation pages (/docs, /api, /pricing, /README) are empty, rendering only 'Connect wallet'.","Endpoint path is hardcoded to order ID 41; unclear if other order IDs are supported or how orders are created.","The 'Premium API Access' description is generic and does not explain what data is returned."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/41/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/41/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 and returns a valid x402 402 challenge, confirming pricing and network.
