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.
API tools are available on paid plans.
Click New and define the request:
Method and URL

Add any auth headers, tokens, or keys the endpoint needs. They are stored securely.
Inputs
Describe the inputs the agent should collect and pass to the request.
Test
Run a test request to confirm it works before saving.
Common uses: check live stock or order status, create a support ticket, or kick off a workflow in your backend, all without a human stepping in.
