It is part of a broader platform that offers a variety of pay-per-call APIs 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/164/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 endpoint accepts POST requests and returns application/json.\n\nThe broader platform advertises endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation — all at the same $0.02 price point. However, documentation beyond the landing page is extremely sparse: the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The actual data returned by this order-status endpoint is unknown beyond the MIME type (application/json).","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","USDC micropayment API","pay-per-request API","Base network API","lowpaymentfee","order tracking"],"warnings":["Endpoint is hardcoded to order ID 164 — unclear if other order IDs are supported or how to discover them","No OpenAPI specification or request/response schema available","All documentation pages (/docs, /api, /pricing, /README) render only 'Connect wallet' with no content","The description 'Premium API Access' is generic and does not explain what data is returned","No examples of successful responses are available anywhere in the crawled material"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/164/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/164/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 (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base).
