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 advertises a maxAmountRequired of 20,000 base units of USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 6 decimals), which equals $0.02 USD per call. Payment is made by including an X-PAYMENT header with the appropriate x402 payment proof. There are no API keys, no rate limits, and no subscription commitments — callers pay per request.\n\nThe specific endpoint `/api/v1/orders/16/status` appears to be a single-resource order-status lookup. The platform's landing page lists many other endpoints across categories like sentiment analysis, text summarization, embeddings, price feeds, gas estimates, geocoding, and more, all at the same $0.02 price point. Documentation pages beyond the landing page returned only a \"Connect wallet\" prompt with no further technical detail, so the request/response schemas for this endpoint are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","per-request-micropayment","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee"],"warnings":["No request or response schema available — input/output formats are unknown.","Documentation, pricing, and README pages all return only 'Connect wallet' with no technical content.","The endpoint path is hardcoded to order ID 16; it is unclear whether other order IDs are supported or how to discover them.","The platform lists many endpoints but none have published documentation beyond the landing page summary."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/16/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/16/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).
