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/6/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 attaching an X-PAYMENT header with a valid x402 payment proof. The endpoint responds with application/json.\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 data the order status response actually contains. The platform appears to be a demonstration or early-stage deployment of x402-gated APIs rather than a mature production service.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-call","order-status","micropayment","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment API","lowpaymentfee","USDC pay-per-call","Base network API","402 payment required endpoint"],"warnings":["No API documentation available — docs, pricing, and README pages all show only 'Connect wallet'","No OpenAPI or request/response schema provided","Endpoint is hardcoded to order #6; unclear if other order IDs are supported","Platform may be a demonstration deployment rather than a production service"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/6/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/6/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 captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the endpoint is hardcoded to a single order ID.
