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/23/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 requires an x402 payment of up to 20,000 base units of USDC (contract `0x8335…2913` on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the platform's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain to address `0x1A2B…85F3` with a 300-second timeout. The response MIME type is `application/json`.
The platform advertises no API keys, no rate limits, and instant access. However, documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all returned only a "Connect wallet" prompt with no substantive content, so there is no schema documentation, request/response examples, or detailed endpoint descriptions available. The specific semantics of "account statements" for account ID 23 are unclear — it may be a demo or placeholder resource. Without further documentation, the exact request body format and response structure cannot be determined.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schemas, no examples, and the endpoint path (accounts/23/statements) appears to reference a hardcoded account ID with no explanation. All doc pages returned only 'Connect wallet' with no content.
Warnings
- —No request or response schema documentation available — all doc pages return only 'Connect wallet'
- —The endpoint path references a specific account ID (23) with no explanation of what this resource represents
- —No OpenAPI spec, no AI plugin manifest, no robots.txt or agents.txt found
- —Actual functionality behind 'account statements' is unverified and may be a placeholder
