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/43/statements`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-protocol APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all payable per-request in USDC on the Base network with no API keys or rate limits required.
The specific endpoint probed here returns an x402 challenge requesting up to 20,000 base units of USDC (0x8335…2913 on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the platform's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain via the x402 "exact" scheme, with a 300-second timeout window. The response MIME type is `application/json`.
Documentation on the site is extremely thin — 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 from the crawl. The endpoint's purpose ("account statements") and expected input/output formats must be inferred from the URL path and description alone. The platform lists many other endpoints (analytics, AI, finance, utilities) at the same price point, but none have documented schemas either.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI spec, no request/response schema, and no documentation beyond a wallet-connect prompt. The purpose of this specific endpoint (account 43 statements) is unclear and undocumented.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —Docs, API, pricing, and README pages all render only 'Connect wallet' with no usable content
- —The endpoint path references a hardcoded account ID (43) — unclear if this is parameterizable
- —No example request or response bodies are available anywhere in the crawl
- —The broader platform lists many endpoints but none appear to have documented schemas
