It is part of a broader platform that offers a variety of API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per call and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/49/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. No API keys or rate limits are advertised; callers pay per request using the x402 X-PAYMENT header. The timeout for payment settlement is 300 seconds.\n\nThe broader platform lists endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, validation, and more — all at the same $0.02 price point. However, no OpenAPI schema, detailed documentation, or example request/response payloads are available from the crawled pages (docs, pricing, and README pages all returned only a \"Connect wallet\" prompt). The actual data returned by this specific order-status endpoint is unknown beyond the stated mimeType of application/json.","tags":[],"capabilities":["x402-payment","order-status","usdc-base","micropayment","per-request-billing","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","micropayment API","pay-per-call API","Base USDC API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available — docs, pricing, and README pages return only 'Connect wallet'","Endpoint path is hardcoded to order ID 49; unclear if this is a demo or production resource","No example request or response bodies are documented anywhere","The broader platform lists many endpoints but none have documented schemas or examples"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/49/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/49/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).
