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 a 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 site's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain via the x402 \"exact\" scheme, with a 300-second timeout window. No API keys or rate limits are advertised; access is granted purely through the x402 payment header.\n\nThe platform's landing page lists endpoints across four categories — Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure — all at the same $0.02 price point. However, documentation beyond the landing page is essentially empty (all sub-pages just show \"Connect wallet\"), so the actual request/response schemas for this statements endpoint are unknown. The endpoint's purpose (\"account statements\") and what data it returns remain unclear from available material.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","account-statements","post-method","no-api-key"],"categories":["finance","data"],"synonyms":["account statements API","x402 paid API","USDC micropayment API","Base network API","lowpaymentfee","pay-per-call endpoint","crypto-gated API"],"warnings":["No API documentation available — all doc/pricing/readme pages are empty stubs","Request and response schemas for this endpoint are completely unknown","The purpose of 'account 142 statements' is unclear; it may be a demo or placeholder","No OpenAPI spec or ai-plugin manifest found"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/142/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/142/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no request/response schema, and no explanation of what 'account statements' actually returns.
