x402-gated account statements endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statements via a POST request to `/api/v1/accounts/194/statements`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services — all gated behind the x402 payment protocol on the Base network.
The specific endpoint probed charges up to $0.02 per request (20,000 base units of USDC with 6 decimals) and settles payments on-chain to a designated wallet. The x402 challenge is live and returns a well-formed 402 response with version 1 of the protocol. Payment is in USDC (contract `0x8335…2913` on Base) using the "exact" scheme. No API keys or rate limits are advertised; access is granted purely through the x402 payment header.
Documentation on the site is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the statements endpoint actually returns. The endpoint path suggests financial account statement data, but the actual payload structure is unknown. The platform's landing page lists many endpoints at $0.02 each across multiple categories, but without documentation it is unclear what data quality or sources back these services.

Quality
The x402 challenge is live and well-formed, confirming the endpoint exists and accepts payments. However, there is no documentation, no OpenAPI schema, no request/response examples, and the docs pages are empty. The purpose and output of the statements endpoint can only be guessed from the URL path.
