Creates a new voice AI agent. Returns HTTP 201 with { "agent_id": "...", "state": "created" }.

The quickest path is creating an agent in the dashboard (Auto Build) and copying its ID. Use the API when you need to programmatically provision agents at scale or integrate agent creation into your deployment pipeline.

Common 400 errors

Message	Fix
`agent_config is required`	Wrap your config in `{ "agent_config": { ... } }`
`tasks is required`	The `tasks` array must have at least one entry
`toolchain.pipelines must be array of arrays`	Use `[["transcriber","llm","synthesizer"]]`, not `["transcriber","llm","synthesizer"]`

Next steps

After creating an agent, place a call with POST /call using the returned agent_id. See the API Quickstart for a complete end-to-end example.
