It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request, settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/79/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 (version 1). There are no API keys, no rate limits, and no subscription commitments — callers pay per request.\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 is confirmed live (returns 402 with a valid x402 challenge), but the actual response payload after successful payment is unknown. The platform advertises categories including analytics metrics, reports, data export, insights, 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.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","no-rate-limit"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee","premium API access","402 payment endpoint"],"warnings":["No OpenAPI spec or response schema available — actual response payload after payment is unknown.","Documentation pages (docs, pricing, API, README) all render only 'Connect wallet' with no content.","The endpoint path is hardcoded to order ID 79; it is unclear if other order IDs are supported or how to discover them.","The platform lists many endpoint categories (AI, finance, analytics, etc.) but none have documented schemas or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/79/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/79/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 challenge, but there is no documentation, no OpenAPI spec, no request/response schema, and no examples.
