Any of Hex's 4 triggers in the catalog, including New Project Run, List Groups, List Projects and List Users. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Langfuse when something happens in Hex? Any of Langfuse's 14 actions, including Add Comment, Add Dataset, Add Dataset Item and Add Prompt. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Langfuse to Hex? Yes. When something happens in Langfuse, your agent can act in Hex too. This page covers both directions: Langfuse's triggers and Hex's actions are listed here as well. ### ### Do I have to build a connector for Hex or Langfuse? No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use Hex and Langfuse without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
