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/25/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 returns a 402 challenge requesting payment in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base). The `maxAmountRequired` is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. Payment is made via the x402 `exact` scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, with a timeout of 300 seconds. The response MIME type is `application/json`.
The platform advertises a uniform $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments. Documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all appear to require a wallet connection and contain no substantive content when crawled without one. As a result, there is no detailed documentation available about request/response schemas, input parameters, or the specific data returned by the statements endpoint. The endpoint title "Premium API Access" is generic and does not clarify what account statements contain or what account ID 25 refers to.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation, no request/response schema, no examples, and the endpoint purpose ('account statements' for account 25) is unexplained. The docs, pricing, and README pages are all empty behind a wallet-connect gate.
Warnings
- —No API documentation available — all doc pages require wallet connection and return no content when crawled
- —The endpoint path references a specific account ID (25); it is unclear whether this is parameterized or fixed
- —No request body schema or response schema is documented anywhere
- —The description 'Premium API Access' is generic and does not describe what data is returned
- —Cannot verify what 'account statements' actually contain without authenticated access
