The specific resource at `/api/v1/generate/resource/118` is listed as \"Premium API Access\" and accepts POST requests. Payment is handled via the x402 exact-payment scheme — callers attach an X-PAYMENT header with a USDC payment on Base, and the endpoint returns its result as application/json.\n\nThe broader platform advertises endpoints across 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 utilities (geocoding, validation, conversion, generation). All endpoints are priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments required.\n\nThe specific resource probed (resource/118) advertises a maxAmountRequired of 20,000 base units of USDC (which has 6 decimals), equating to $0.02 per call. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base. No OpenAPI schema, detailed documentation, or example request/response bodies were found in the crawl — the docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","json-response","no-api-key","post-method"],"categories":["api-gateway","infrastructure"],"synonyms":["x402 API","pay-per-call API","USDC API","Base network API","micropayment API","lowpaymentfee","premium API access"],"warnings":["No OpenAPI or JSON schema available for request or response bodies","Documentation pages (docs, pricing, API, README) all return only a 'Connect wallet' prompt with no substantive content","The specific function of /api/v1/generate/resource/118 is unclear — 'Premium API Access' is a generic label","Cannot verify what data or service this endpoint actually returns without making a paid call"],"endpointUrl":"https://lowpaymentfee.com/api/v1/generate/resource/118","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/generate/resource/118","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base).
