# Infini Fund API

Organization fund APIs for Infini UID transfers, withdrawals, withdrawal fees, and USDT/USDC/USD available balances. All endpoints use the independent `/v2/funds` prefix.

Requests require [HMAC-SHA256 authentication](/docs/en/4-authorization) and the `fund.withdraw` permission. To use **Try it**, save Sandbox credentials on [API Credentials](/credentials), or enter Key and Secret under **Security → HMAC**.
