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/28/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, 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 maximum amount required is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). 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 flat $0.02 per request across all its endpoints, with no API keys, no rate limits, and no minimum commitments. However, documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so the actual request/response schemas for this endpoint are unknown. The endpoint path suggests it retrieves financial statements for a specific account (ID 28), but no further details on input parameters or response structure are available.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it is operational. However, there is no documentation, no OpenAPI schema, no request/response examples, and the docs/pricing/API pages are all blank beyond a 'Connect wallet' prompt. The endpoint path (/accounts/28/statements) is oddly specific (hardcoded account ID), and the actual functionality is unclear.
Warnings
- —No API documentation available — all doc pages return only 'Connect wallet'
- —No request or response schema provided; input parameters and output format are unknown
- —The endpoint path contains a hardcoded account ID (28), which may indicate a demo or placeholder rather than a general-purpose API
- —Platform appears to be a generic multi-category API storefront with minimal substance behind the landing page
