When a token is issued for an agentic interaction, Auth0 includes the `agent_id` (or `external_agent_id`, when set) in the resulting tenant log entry.

## Supported grant types

Auth0 records agent identity in logs for the following grant types:

* `client_credentials` grants from agent-linked clients
* `refresh_token` grants for agent-linked clients
* OBO token exchange grants
* Standard login grants where the client is agent-linked

## Query logs

You can query the `agent_id` via the Management API log endpoints, enabling per-agent audit and anomaly detection:

```http theme={null}
GET /api/v2/logs?q=agent_id:agt_72jbvv7LfRKYp59gtRLtkn
```
