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/17/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 charges up to $0.02 per request (20,000 base units of USDC, which has 6 decimals = $0.02), settled in USDC on Base to the payee address `0x1A2B...85F3`. The x402 challenge was successfully captured, confirming the endpoint is live. Payment is handled via the "exact" scheme with a 300-second timeout. 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 further content. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available. The endpoint path suggests it returns financial statement data for a specific account (account ID 17), but without documentation it is unclear what request body is expected or what the response structure looks like. The platform advertises no API keys, no rate limits, and instant access, with a flat $0.02 per request pricing model across all endpoints.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request format, response schema, or what data is actually returned. Docs pages are empty. No OpenAPI spec. This is effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content
- —No OpenAPI or request/response schema provided; request body format is unknown
- —Endpoint path references a hardcoded account ID (17) — unclear if this is parameterizable or a demo
- —The broader platform lists many endpoints but none have documented schemas
