x402-gated account statements endpoint on Base, pay $0.02 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/190/statements`. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, all gated behind the x402 payment protocol on the Base network.
The endpoint returns a 402 Payment Required challenge requesting payment in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base) using the "exact" scheme. The maximum amount required is 20,000 base units, which at 6 decimals for USDC equals $0.02 per request. Payment is sent 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 across all its endpoints, with no API keys, no rate limits, no minimums, and instant access. However, documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so the exact request body schema, response format, and what data the "account statements" endpoint actually returns remain undocumented. The specific endpoint path includes an account ID (190), suggesting it retrieves financial or transactional statement data for a particular account, but this is inferred from naming conventions only.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation on request/response schemas, no OpenAPI spec, and all doc pages are empty. The purpose of the 'account statements' endpoint is only inferable from its URL path.
Warnings
- —No API documentation available — all doc/pricing/README pages return only 'Connect wallet'
- —Request body schema and response format are completely undocumented
- —The account ID '190' is hardcoded in the endpoint path; unclear if other account IDs are accessible or what data is returned
- —No OpenAPI or machine-readable schema provided
