It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request settled in USDC on the Base network.\n\nThe specific resource `/api/v1/orders/117/status` accepts POST requests and requires an X-PAYMENT header carrying a valid x402 payment proof. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds. The response MIME type is application/json.\n\nThe platform advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /api, /README) all resolve but contain only a \"Connect wallet\" prompt with no substantive technical documentation. There is no OpenAPI spec, no request/response schema beyond the x402 challenge metadata, and no example payloads. The actual data returned by this order-status endpoint is unknown — it could be e-commerce order tracking or an internal demo resource. The endpoint is live and returning a well-formed x402 challenge.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status API","x402 micropayment","USDC payment API","Base network API","pay-per-call","lowpaymentfee"],"warnings":["No OpenAPI or request/response schema available — actual payload structure is unknown","All documentation pages (/docs, /pricing, /api, /README) return only 'Connect wallet' with no technical content","The endpoint targets a hardcoded order ID (117); unclear whether this is a demo or production resource","No information on what data the order-status response actually contains"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/117/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/117/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 and returns a valid x402 challenge, but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the purpose of this specific order-status resource is unclear.
