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/20/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 USDC per request (maxAmountRequired of 20,000 base units with USDC's 6 decimals). Payment is settled on-chain via the x402 "exact" scheme to a designated wallet address. The platform advertises a flat $0.02/request pricing across all its endpoints, with no API keys, no rate limits, and no minimum commitments required.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what the account statements endpoint actually returns. The endpoint is confirmed live (returns a valid 402 challenge), but the lack of documentation makes it difficult to know the expected POST body or the shape of the response.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payment. However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty beyond a wallet-connect prompt. The purpose of this specific endpoint (account statements for account ID 20) is unclear and undocumented.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —All doc/pricing/API pages render only 'Connect wallet' with no substantive content
- —The endpoint path includes a hardcoded account ID (20) — unclear if this is parameterizable
- —No request body schema or response schema is documented anywhere
- —The broader platform lists many endpoints but none appear to have public documentation
