All endpoints are pay-per-request at $0.02 each, settled in USDC on the Base network. No API keys, accounts, or rate limits are required — callers simply attach an x402 payment header to each request.\n\nThe specific endpoint at `/api/v1/orders/90` is listed as \"Premium API Access\" and returns a 402 challenge requesting up to 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02. The payment scheme is \"exact\" with a 300-second timeout. The endpoint accepts POST requests and returns `application/json`.\n\nThe broader platform advertises endpoints in four categories: Data & Analytics (metrics, reports, data export, insights), AI & Machine Learning (sentiment analysis, text summarization, classification, embeddings), Finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and Infrastructure (geocoding, validation, conversion, generation). Documentation pages exist at /docs, /pricing, and /api but currently render only a wallet-connect prompt with no substantive content, so the actual request/response schemas for individual endpoints are unknown.","tags":[],"capabilities":["x402-payment","pay-per-request","usdc-base","data-analytics","ai-inference","sentiment-analysis","text-summarization","classification","embeddings","finance-data","crypto-quotes","gas-estimates","geocoding","validation","conversion"],"categories":["api-platform","ai","finance","data"],"synonyms":["low payment fee","x402 api","pay per call api","usdc api","base network api","micropayment api","no-auth api"],"warnings":["Documentation pages (/docs, /pricing, /api, /README) render only a wallet-connect prompt with no actual content","No OpenAPI or schema available — request and response formats for all endpoints are unknown","The specific endpoint /api/v1/orders/90 is labeled 'Premium API Access' but is not listed on the homepage catalog, making its purpose unclear","No information on uptime, SLAs, or data sources behind any of the advertised endpoints"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/90","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/90","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The x402 challenge is live and well-formed, confirming the endpoint works and pricing is clear ($0.02 USDC on Base).
