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/167/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 (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the X-PAYMENT header per the x402 protocol, with no API keys or rate limits required. The payTo address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, and the maximum timeout is 300 seconds.\n\nThe platform advertises a wide catalog of endpoints (metrics, reports, sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, validation, and more), all at the same $0.02 price point. However, documentation pages beyond the landing page returned only a \"Connect wallet\" prompt with no further technical detail, so the actual response schema and behavior of this specific order-status endpoint are not documented in the crawled material.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No API documentation available — all doc pages return only 'Connect wallet' with no content.","Response schema is unknown; no example responses are available.","Endpoint path is hardcoded to order #167; unclear if this generalizes to other order IDs.","The platform lists many endpoints on its landing page but none have documented schemas or behavior."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/167/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/167/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).
