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/24/statements`. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, 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 to a specified wallet address using the "exact" scheme. The platform advertises a uniform $0.02/request pricing across all its endpoints, with no API keys, no rate limits, and no minimum commitments required.
The endpoint returned a valid 402 challenge confirming it is live. However, documentation is extremely thin — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what "account statements" actually contain or what parameters the POST body expects. The endpoint path includes a hardcoded account ID (24), and it is unclear whether this is parameterizable or what data model underlies the response. Prospective users should be aware that this endpoint's actual functionality and data content are unverified beyond the x402 challenge metadata.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming pricing and network details. However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no clarity on what data the endpoint actually returns. This is effectively a stub listing.
