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/164/statements`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services.
The specific endpoint probed returns a 402 challenge requesting payment of up to 0.02 USDC (20,000 base units with 6 decimals) on the Base network, settled to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the USDC token contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`. The x402 scheme is "exact" with a 300-second timeout. The response MIME type is `application/json`.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned 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 contains or what POST body it expects. The platform advertises $0.02/request across all endpoints, no API keys, no rate limits, and instant access. Without further documentation it is unclear what data this particular endpoint returns or what input parameters it accepts.

Quality
The endpoint is live and returns a valid x402 challenge, but there is virtually no documentation: no OpenAPI spec, no request/response schema, no explanation of what 'statements' contains, and all doc pages are empty. This is effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all return only 'Connect wallet' with no content.
- —No request body schema provided; unclear what POST parameters the endpoint expects.
- —No response schema or example; unknown what data is returned upon successful payment.
- —The endpoint path includes a hardcoded account ID (164); unclear if this is parameterizable or a demo.
- —Platform appears to be a generic x402 showcase; actual data behind endpoints is unverified.
