It is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all payable per-request in USDC on the Base network.\n\nThe specific endpoint probed here returns an x402 challenge requesting up to 20,000 base units of USDC (0.02 USD) per call, settled on-chain to the specified payTo address. The asset contract (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) is the canonical USDC contract on Base. No API keys or rate limits are advertised; access is gated purely by the x402 payment protocol. The response MIME type is `application/json`.\n\nDocumentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what the \"account statements\" endpoint actually returns or what input parameters it expects. The platform's landing page lists many endpoints across multiple categories, all priced at $0.02/request, but provides no technical documentation for any of them. The exact purpose and data format of this particular endpoint remain unclear.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","per-request-pricing","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 paid API","USDC micropayment API","lowpaymentfee","Base network API","pay-per-call API"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.","No request or response schema provided; it is unknown what parameters the POST endpoint accepts or what data it returns.","The purpose of 'account statements' for account ID 163 is entirely undocumented.","The broader platform lists many endpoints but none have technical documentation."],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/163/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/163/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request parameters, response schema, or what 'account statements' actually contains.
