It is one of many endpoints offered by the lowpaymentfee.com platform, which provides a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/128/status` accepts a POST and returns `application/json`. Payment is handled inline: callers attach an `X-PAYMENT` header containing a signed x402 payment voucher for up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). No API keys, accounts, or rate limits are advertised — access is purely pay-per-use.\n\nNote that this particular URL is hard-coded to order ID 128. It is unclear from the available material whether the endpoint is parameterized for arbitrary order IDs or whether this is a demonstration/sample resource. The broader platform lists many other endpoints (sentiment analysis, text summarization, geocoding, price feeds, etc.) at the same $0.02 price point, but documentation pages returned only a wallet-connect prompt with no further technical detail.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","lowpaymentfee","Base network API","402 payment required","order tracking"],"warnings":["Documentation pages (/docs, /api, /pricing, /README) all returned only a 'Connect wallet' prompt with no technical content.","Endpoint URL is hard-coded to order ID 128; unclear whether other order IDs are supported or if this is a demo resource.","No OpenAPI spec, no response schema, and no example responses are available.","The broader platform advertises many endpoints (AI, finance, utils) but none have documented schemas — treat all with caution."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/128/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/128/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).
