# Create Agent

> Create a new agent. Returns a one-time agentToken.

Create a new agent. The authenticated user becomes the owner of the agent.

The response includes `{ agent, agentToken }`. The `agentToken` is displayed **only once** at creation time -- store it immediately so your agent can authenticate later.

The agent starts in an unverified state. You must call the [Verify Agent](/api-reference/agents/verify) endpoint before the agent can connect via the SDK.

<Warning>
  The agent token is shown only once. Store it securely -- it cannot be retrieved later.
</Warning>
