It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind the x402 payment protocol on the Base network.\n\nThe specific endpoint probed requires an x402 payment of up to 20,000 base units of USDC (contract `0x8335…2913` on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the platform's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain to address `0x1A2B…85F3` with a 300-second timeout. The response MIME type is `application/json`.\n\nThe platform advertises no API keys, no rate limits, and instant access. However, documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all returned only a \"Connect wallet\" prompt with no substantive content, so there is no schema documentation, request/response examples, or detailed endpoint descriptions available. The specific semantics of \"account statements\" for account ID 23 are unclear — it may be a demo or placeholder resource. Without further documentation, the exact request body format and response structure cannot be determined.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","account-statements","json-response","post-method"],"categories":["finance","data"],"synonyms":["account statements API","x402 paid API","USDC micropayment API","Base network API","pay-per-call endpoint","lowpaymentfee","financial statements"],"warnings":["No request or response schema documentation available — all doc pages return only 'Connect wallet'","The endpoint path references a specific account ID (23) with no explanation of what this resource represents","No OpenAPI spec, no AI plugin manifest, no robots.txt or agents.txt found","Actual functionality behind 'account statements' is unverified and may be a placeholder"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/23/statements","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/23/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schemas, no examples, and the endpoint path (accounts/23/statements) appears to reference a hardcoded account ID with no explanation.
