What it does
- 01
Brief it like a new hire
An agent’s instructions are a page of plain writing, not a flowchart, with variables and your own HTTP tools written into it.
- 02
Feels like a person
Cut in and it stops mid-word and listens. It follows the caller between Hindi and English, and hangs up when the call is over.
- 03
One request starts a call
Every agent has its own API key. One POST starts a call from a browser or a phone, and each call is kept with its transcript, length and cost.
