It is part of a broader platform offering dozens 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/109/status` is listed under the title \"Premium API Access.\" The x402 challenge confirms it is live, accepting exact-scheme payments of up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) to wallet `0x1A2B...85F3`. Payment is made via the `X-PAYMENT` header; no API keys or accounts are required. The response MIME type is `application/json`.\n\nDocumentation on the site is extremely thin — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no usage examples. The endpoint path suggests it returns order status information, but the exact response shape is unknown. The broader platform advertises categories like sentiment analysis, text summarization, embeddings, geocoding, price feeds, and more, all at the same $0.02 price point.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","json-response"],"categories":["commerce","data"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee","order tracking","402 payment required"],"warnings":["No OpenAPI spec or response schema available — response format is unknown","Documentation pages (/docs, /pricing, /api, /README) all render only 'Connect wallet' with no content","Endpoint is hardcoded to order ID 109; unclear if other order IDs are supported at different paths","The broader platform lists many API categories but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/109/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/109/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 402 challenge, confirming pricing and network.
