It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe x402 challenge confirms the endpoint is live and accepts exact-scheme payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maxAmountRequired is 20000 base units, which equals $0.02 (USDC uses 6 decimals). No API keys are needed; callers simply attach the X-PAYMENT header with a valid payment proof. The platform advertises no rate limits and instant access.\n\nNote that this specific endpoint path (/api/v1/orders/121/status) is not listed among the platform's advertised API categories (analytics, AI, finance, infrastructure). It appears to be an order-status lookup, possibly a demo or internal endpoint. Documentation pages (/docs, /pricing, /api, /README) all returned only a \"Connect wallet\" prompt with no substantive content, so the actual response schema and detailed behavior of this endpoint are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","micropayment","no-api-key","pay-per-request"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["Documentation pages (/docs, /pricing, /api, /README) contain no usable content — only a 'Connect wallet' prompt.","This specific endpoint path (/api/v1/orders/121/status) is not listed among the platform's advertised APIs; it may be a demo or internal route.","No response schema or example responses are available; actual output format is unknown.","No OpenAPI spec or structured API documentation was found."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/121/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/121/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 (402 challenge captured) and pricing is clear ($0.02 USDC on Base).
