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/146/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, crypto, and utility services.
The specific endpoint probed here is gated by the x402 payment protocol (version 1) using the "exact" scheme on the Base network. The maximum amount required per call is 20,000 base units of USDC (contract `0x8335...2913`), which equals $0.02 USD (USDC uses 6 decimals). Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds. The endpoint accepts POST requests and returns `application/json`.
The broader platform advertises a flat $0.02 per request across all endpoints, with no API keys, no rate limits, no minimums, and instant access. However, documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all returned only a "Connect wallet" prompt with no substantive content, so the actual request/response schemas for this specific statements endpoint are unknown. The endpoint is live (returning a proper 402 challenge), but without documentation or examples, the exact input parameters and response format cannot be determined.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and all doc pages return only a wallet-connect stub. The purpose of this specific 'account 146 statements' endpoint is unclear beyond its title.
Warnings
- —No API documentation available — all doc pages (/docs, /pricing, /api, /README) return only a 'Connect wallet' prompt with no content.
- —Request and response schemas for this endpoint are completely unknown.
- —The endpoint is scoped to a specific account ID (146); it is unclear whether other account IDs are supported or what 'statements' contains.
- —The broader platform lists many endpoints across diverse categories (AI, finance, utilities) all at $0.02 — the actual functionality behind each is unverified.
