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 infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/155/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 (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, which uses 6 decimals), equating to $0.02 USD per call. Payment is made via the X-PAYMENT header per the x402 protocol, with a timeout of 300 seconds. No API keys or rate limits are advertised; access is instant upon payment.\n\nDocumentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no detailed description of what the order status response contains. The endpoint is live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know the exact response format or what inputs (if any) the POST body should contain.","tags":[],"capabilities":["x402-payment","usdc-base-network","order-status","pay-per-request","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","USDC payment API","pay-per-call","Base network API"],"warnings":["Documentation pages (/docs, /api, /pricing, /README) all render only 'Connect wallet' with no actual content","No OpenAPI or schema available — request body format and response structure are unknown","Endpoint path is hardcoded to order 155; unclear if other order IDs are supported or how to discover them","The broader platform lists many API categories (AI, finance, analytics) but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/155/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/155/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'.
