 | `name` | Agent name |

-| `oauthEnabled` | Whether the publish channels include OAuth |
+| `oauthEnabled` | `true` when the Agent publishes OAuth and the platform has enterprise OIDC plus a non-empty OAuth channel audience configured; `false` when the Agent switch is on but the platform cannot yet verify callers |
 | `oauthAccessMode` | `all_idaas_users` means all enterprise users; `specified_users` means only the addresses on the allowlist |
 
 Agents that are unpublished, stopped, or nonexistent uniformly return `exists: false`, without exposing draft information.
