x402-payable account statements endpoint on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides account statement data for a specific account (ID 141) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).
The 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. The platform uses the x402 protocol (version 1) with the "exact" payment scheme, meaning each request requires a one-time micropayment.
The specific functionality of this particular endpoint — account statements — is not well documented. The crawled landing page lists many other endpoints but does not include this `/api/v1/accounts/141/statements` path among its advertised APIs. The request and response schemas are not documented, and the docs/pricing/API pages returned only a wallet-connect prompt with no additional content. As a result, the exact input parameters and output format remain unclear.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation of request parameters, response schema, or what 'account statements' actually returns. The docs, pricing, and API pages are empty beyond a wallet-connect prompt. The endpoint path itself is not listed among the platform's advertised APIs.
