It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. However, the specific endpoint being listed here (`/api/v1/accounts/191/statements`) is not explicitly documented on the landing page among the advertised APIs, so its exact response schema and input parameters are unknown.\n\nThe x402 challenge was successfully captured (HTTP 402 with version 1 challenge), confirming the endpoint is live. The payment scheme is \"exact\" with a 300-second timeout. No OpenAPI spec, detailed documentation, or example responses were found in the crawl — the docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no further content.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","json-response","post-method","no-api-key"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 finance API","pay-per-call statements","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["The endpoint /api/v1/accounts/191/statements is not listed among the publicly advertised APIs on the landing page — its purpose and data format are inferred from the URL path only.","No OpenAPI spec, request schema, or response schema is available; integration requires trial-and-error.","All documentation pages (docs, pricing, API, README) returned only a 'Connect wallet' prompt with no substantive content.","The account ID '191' is hardcoded in the path — it is unclear whether this is a demo account or a specific resource."],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/191/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/191/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 no OpenAPI spec, no documentation of request/response schemas, no example payloads, and the specific /accounts/191/statements path is not listed among the site's advertised APIs.
