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/40/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 returns a 402 challenge requesting payment in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base). The `maxAmountRequired` is 20,000 base units, which at 6 decimals for USDC equals $0.02 per request. This matches the site's advertised flat pricing of $0.02/request across all endpoints. Payment is made via the x402 `exact` scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, with a 300-second timeout.
The platform advertises no API keys, no rate limits, and instant access. However, documentation is extremely thin — 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 description of what the account statements endpoint actually returns or what input parameters it expects. The endpoint path suggests it retrieves statements for a specific account (ID 40), but the semantics are unclear.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no documentation of request/response formats, no examples, and the docs pages are empty. The purpose of this specific endpoint (account 40 statements) is unexplained, making it essentially a stub listing.
Warnings
- —No API documentation available — all doc pages render only 'Connect wallet' with no content
- —No OpenAPI or request/response schema provided for this endpoint
- —The endpoint path references a hardcoded account ID (40); unclear if this is parameterizable or what data it returns
- —No examples of successful responses exist in the crawled material
