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/85/statements`. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, 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 on Base using USDC (contract `0x8335…2913`) with the "exact" scheme. No API keys or rate limits are advertised — access is granted purely via the x402 payment header. The endpoint returns `application/json` and accepts POST requests.
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 spec, no request/response schema documentation, and no examples of what the statements endpoint actually returns. The endpoint itself is confirmed live (402 challenge captured), but without documentation it is unclear what parameters the POST body should contain or what shape the response takes. The platform lists many other endpoints at the same $0.02 price point across analytics, AI, finance, and utility categories, but this specific listing covers only the account statements resource.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC per request on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The purpose of 'account statements' for account ID 85 is entirely opaque.
Warnings
- —No API documentation available — /docs, /api, /pricing, and /README all return only a 'Connect wallet' prompt with no content.
- —No request body schema or response schema documented; callers cannot know what parameters to send or what data to expect.
- —The endpoint path includes a hardcoded account ID (85), and it is unclear whether this is parameterizable or what accounts are available.
- —The platform lists many diverse endpoints (AI, finance, utilities) all at $0.02 — the actual functionality behind each is unverified.
