The specific resource `/api/v1/accounts/130` sits within a broader platform that offers multiple API 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 for this endpoint confirms it is live and accepts exact-scheme payments of up to 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payments are sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The endpoint accepts POST requests and returns application/json.\n\nThe exact functionality behind `/api/v1/accounts/130` is not documented beyond the label \"Premium API Access.\" The platform's docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further technical documentation, OpenAPI spec, or example payloads. Without additional documentation it is unclear what data or service this specific account endpoint returns. The broader platform advertises analytics, AI inference, finance data, and utility endpoints, but this particular path does not map to any of those listed categories.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","json-response","no-api-key","post-method"],"categories":["api","infrastructure"],"synonyms":["premium API","pay-per-call API","x402 endpoint","USDC API access","Base network API","micropayment API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available — all doc pages render only 'Connect wallet'","The specific functionality of /api/v1/accounts/130 ('Premium API Access') is not described anywhere","No example request or response payloads are available","The endpoint path suggests an account-specific resource but no details on what it returns"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/130","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/130","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no example request/response, and the specific purpose of /api/v1/accounts/130 is undocumented.
