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/198/statements`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, 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 equals $0.02 per request. Payment is made via the x402 "exact" scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, with a timeout of 300 seconds. The response MIME type is `application/json`.
The platform advertises a uniform $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments. However, documentation beyond the landing page is essentially empty (all subpages just show "Connect wallet"), so the exact request body schema, response format, and what "account statements" specifically contain are unknown. The endpoint path includes an account ID (198), suggesting it retrieves financial or transactional statement data for a specific account, but this is inference only.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no request/response schema, and no explanation of what 'account statements' actually returns. All doc pages are empty ('Connect wallet' only). This is effectively a stub listing.
Warnings
- —No API documentation available — all doc pages return only 'Connect wallet'
- —Request body schema is unknown; no OpenAPI spec or examples provided
- —Response format and content of 'account statements' is entirely undocumented
- —The account ID '198' in the path is hardcoded; unclear if other account IDs are valid or how they are obtained
- —Platform appears to be a generic demo or placeholder — many diverse API categories listed but no substantive documentation for any
