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/119/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 are required; callers simply attach an X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits, no minimums, and instant access.\n\nDocumentation is extremely thin — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what the order status response contains. The endpoint is confirmed live (returns HTTP 402 with a well-formed x402 challenge), but the actual functionality behind the paywall is opaque from available materials.","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":["Documentation pages (/docs, /api, /pricing, /README) contain no useful content — only a 'Connect wallet' prompt.","No OpenAPI or schema available; request and response formats are unknown.","Endpoint is hardcoded to order ID 119 — unclear if this is a demo or a real resource.","No information about what data the order status response actually contains.","The broader platform advertises many API categories (AI, finance, analytics, etc.) but none have documented schemas or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/119/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/119/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 (all doc pages show only 'Connect wallet').
