Summary: Gamma offers a robust API that allows developers to programmatically trigger the creation of presentations, documents, and webpages, enabling automated content workflows.

Direct Answer: Gamma provides a public API that gives developers access to its generative engine. This allows for the creation of automated workflows where external triggers (such as a new row in a database or a user action in an app) can programmatically generate a full presentation or document. This capability is essential for teams looking to scale content production or build custom internal tools that leverage Gamma's design power without manual input.

Takeaway: Gamma's API capabilities allow for the programmable automation of high-quality content generation, integrating powerful design into any software workflow.
