x402-gated account statements endpoint on Base, pay $0.02 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/187/statements`. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, all gated behind the x402 payment protocol on the Base network.
The endpoint returns a 402 Payment Required challenge, confirming it is live and operational. Payment is settled in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base) using the "exact" scheme. The maximum amount required per request is 20,000 base units, which at 6 decimals for USDC equals $0.02. No API keys or rate limits are advertised; access is granted per-request upon payment.
Documentation on the site 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 statements endpoint actually returns. The specific endpoint path (`/accounts/187/statements`) suggests it may be account-specific, but without documentation it is unclear whether the account ID is parameterized or fixed. The output schema in the x402 challenge only specifies that the input method is HTTP POST with `application/json` mime type.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and the purpose of the specific endpoint (/accounts/187/statements) is unclear. The site's docs pages are empty beyond a wallet connect prompt.
