x402-gated account statements endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statements via a POST request to `/api/v1/accounts/133/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/Web3 data, and utility services — all gated behind the x402 payment protocol on the Base network.
The specific endpoint probed here requires an x402 payment of up to 20,000 base units of USDC (contract `0x8335…2913` on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the site's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain via the "exact" scheme to address `0x1A2B…85F3`, with a 300-second timeout window. The response MIME type is `application/json`.
Documentation on the site is extremely sparse — the docs, API, pricing, 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" resource actually returns or what POST body it expects. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation it is difficult to know what data is served or what input parameters are accepted. The platform advertises no API keys, no rate limits, and instant access.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is zero documentation on request parameters, response schema, or what 'account statements' actually contains. Docs pages are empty. No OpenAPI spec or examples exist.
