Function Calling / Tool Use, explained
Function calling is how an agent triggers real actions in your tools.
Why it matters for agents
The model calls defined functions with the right arguments, so it can make changes in your systems.
How we use it in production
It is how our agents update records, book time and send messages.

★★★★★
“They didn't lead with function calling. They started with the job we needed done and only brought it in where it fit. The result: we handled 40% more volume with the same headcount.”
★★★★★
“We didn't need to become experts in function calling. They explained what it meant for us in plain English, built it, and the agent paid for itself in five weeks.”
★★★★★
“Our security team sent 60 questions about function calling. Every answer was specific to our setup and came back in writing within the week. We signed, and we're saving about $6,000 a month against the hire we'd budgeted for.”
