The specific resource `/api/v1/accounts/160` 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 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 x402 challenge confirms the endpoint is live, accepting POST requests and settling payments in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base). The `maxAmountRequired` of 20000 base units corresponds to $0.02 (USDC uses 6 decimals). The payment scheme is \"exact\" with a 300-second timeout. The endpoint returns `application/json` responses.\n\nHowever, the specific functionality of `/api/v1/accounts/160` is not documented — it does not appear in the site's listed API catalog, which covers analytics, AI, finance, and utility endpoints. The \"Premium API Access\" label is generic and does not clarify what data or service this particular account endpoint returns. No OpenAPI schema, request/response examples, or detailed documentation were found. The docs, pricing, API, and README pages all rendered 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","infrastructure"],"synonyms":["lowpaymentfee","low payment fee API","x402 API","pay-per-call API","USDC API access","Base network API","micropayment API"],"warnings":["The specific endpoint /api/v1/accounts/160 is not listed in the site's public API catalog — its purpose is unclear","All documentation pages (docs, pricing, API, README) returned only 'Connect wallet' with no substantive content","No OpenAPI spec, request schema, or response examples are available","The generic 'Premium API Access' description does not explain what this endpoint actually does"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/160","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/accounts/160","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 with clear pricing, but the specific functionality of /api/v1/accounts/160 is undocumented.
