# API tools

> Connect your own APIs so the agent can fetch live data and take actions.

API tools let your agent reach your own systems. Register an endpoint once, and the agent can call it to fetch live data or trigger an action in the middle of a conversation. You find them under **APIs** in the Knowledge Sources section.
