The specific resource `/api/v1/policies/95` 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 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 response MIME type is `application/json`. The specific functionality behind `/api/v1/policies/95` is not documented — the name \"Premium API Access\" is generic and does not clarify what data or service this particular policy endpoint returns.\n\nDocumentation on the site is extremely thin: the docs, API, pricing, 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 available. The platform lists many other endpoints (analytics, AI inference, finance, utilities) all at the same $0.02 price point, but details on input parameters and output formats are absent.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","json-response","no-api-key","post-method"],"categories":["api-gateway","pay-per-use"],"synonyms":["lowpaymentfee","low payment fee API","x402 premium API","micropayment API","USDC pay-per-call","Base network API","policies endpoint"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'","The specific functionality of /api/v1/policies/95 ('Premium API Access') is completely undocumented","No OpenAPI spec or request/response schema provided","No example requests or responses available to verify actual output"],"endpointUrl":"https://lowpaymentfee.com/api/v1/policies/95","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/policies/95","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
