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 utility services — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/46/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-request upon payment. The x402 challenge was confirmed live, returning a proper 402 with version 1 challenge metadata.\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 technical detail. There is no OpenAPI spec, no request/response schema documentation, and no examples beyond the landing page's list of endpoints. The endpoint path suggests it retrieves the status of a specific order (order ID 46), but without documentation it is unclear what the response payload looks like or whether the order ID is parameterized.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC payment API","Base network API","pay-per-call order tracking","lowpaymentfee"],"warnings":["No API documentation available — docs, pricing, and README pages render only 'Connect wallet'","No OpenAPI or output schema provided beyond the x402 challenge metadata","Endpoint path is hardcoded to order ID 46; unclear if this is parameterizable","Response format and fields are completely undocumented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/46/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/46/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 challenge, but documentation is essentially nonexistent — docs/pricing/API pages all show only 'Connect wallet'.
