Can I search for talents with specific custom attributes?

Yes! You can use the `search_talents` tool. Your agent will query the database and you can then use `get_talent_details` to inspect all custom fields associated with matching profiles.

How do I see the photos and videos for a talent?

Use the `list_talent_media` tool with the talent's unique ID. The agent will return links to all headshots, videos, and self-tapes stored in their profile.

Where do I find my Casting42 API Key?

Log in to your Casting42 account and navigate to the 'Settings' module. You should find your API key there for integration.
