Can I see which customers have an expired OAuth connection through my agent?

Yes. Use the `list_connections` tool to retrieve all authenticated linked accounts. Your agent will report the current status of each connection, helping you identify which users need to re-authenticate their external platforms.

How do I check if a data synchronization failed recently?

The `list_syncs` tool retrieves the synchronization history for a specific connection. Your agent will expose the log outputs and status indicators, allowing you to debug data processing issues directly from your conversation.

Can my agent retrieve synchronized data records from external APIs?

Absolutely. Use the `list_records` tool with a Connection ID and a model name (e.g., 'contacts'). Your agent will query Nango's storage to fetch the raw synchronized objects, bypassing external API limits natively.
