Any of Stax's 1 trigger in the catalog, including List Payment. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in PDF Blocks when something happens in Stax? Any of PDF Blocks's 17 actions, including Add Image Watermark to PDF, Add Password to PDF, Add restrictions to PDF and Add Text Watermark to PDF. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from PDF Blocks to Stax? PDF Blocks has no triggers in the catalog today, so automations start in Stax. If you need the other direction, ask: your agent reads PDF Blocks's API documentation and adds it. ### ### Do I have to build a connector for Stax or PDF Blocks? 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 Stax and PDF Blocks 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.
