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/76/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 (`/accounts/76/statements`) returned a live 402 challenge requesting up to 20,000 base units of USDC (0.02 USD) per call, settling to a wallet on Base. The x402 challenge specifies the `exact` payment scheme, a 300-second timeout, and returns `application/json`. The endpoint accepts POST requests and is marked as discoverable.
Documentation on the site is extremely thin — the docs, pricing, API, 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 purpose of the "account statements" resource and the expected POST body are not documented, making it difficult to use without additional context or experimentation. The platform advertises a flat $0.02/request pricing model across all its endpoints.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation on request format, response schema, or what 'account statements' actually contains. Docs pages are empty beyond a wallet-connect prompt. No OpenAPI spec or examples exist. This is effectively a stub listing.
