It is one of many endpoints offered by the platform, which spans categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities. All endpoints on the platform are priced at $0.02 per request, payable in USDC on the Base network with no API keys, rate limits, or commitments required.\n\nThe specific endpoint `/api/v1/benefits/26` is labeled \"Premium API Access\" but its exact functionality is not documented beyond that title. The x402 challenge confirms it is live, accepts POST requests, and requires payment of up to 20,000 base units of USDC (0.02 USD given 6 decimals) on Base to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. The response MIME type is application/json.\n\nThe platform's documentation pages (docs, pricing, README) all resolve to a minimal \"Connect wallet\" prompt with no further technical detail, so the exact request/response schema for this endpoint is unknown. The broader platform advertises endpoints for 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","pay-per-request","usdc-base-network","json-response","no-api-key","no-rate-limit"],"categories":["general","infrastructure"],"synonyms":["premium API","lowpaymentfee","x402 endpoint","pay-per-call API","USDC API","Base network API","micropayment API"],"warnings":["Exact functionality of /api/v1/benefits/26 is undocumented—'Premium API Access' is the only descriptor","All documentation pages (docs, pricing, README) render only a 'Connect wallet' prompt with no technical content","No OpenAPI spec, no request/response schema available","Cannot verify what data or service this endpoint actually provides"],"endpointUrl":"https://lowpaymentfee.com/api/v1/benefits/26","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/benefits/26","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via 402 challenge with clear pricing ($0.02 USDC on Base), but there is no documentation of request parameters, response schema, or what 'Premium API Access' actually returns.
