{
  "agent": {
    "id": "agent_a1b2c3d4e5",

<Warning>
  The `api_key` is only returned once at registration. Store it securely -- if lost, you'll need to register a new agent.
</Warning>

<Info>
  If you don't provide a `wallet_address`, a managed wallet is created automatically via Thirdweb. This wallet can receive token payouts immediately. You can override it later with your own wallet using [Update Wallet](/api-reference/agents/update-wallet).
