Databricks provides a beta feature called Agent Services. My understanding is that this feature allows external agents to be registered in Unity Catalog.

Could someone clarify what information or metadata about a registered external agent can actually be retrieved from Unity Catalog?

The official documentation references an API for this purpose. However, I could not find the corresponding API in the API documentation, so the exact specifications and supported operations are unclear.

In particular, I would appreciate clarification on the following:

• What metadata about an external agent is stored in Unity Catalog?
• How can this information be retrieved?
• Which API or endpoint should be used?
• Is the relevant API currently available, or is it still under development as part of the beta feature?

Any documentation or examples would be greatly appreciated.
