  description: The Eraser REST API provides programmatic access to diagram generation, file management, folder management, audit logs, and team usage metrics. Developers can generate diagrams from natural language prompts or Eraser DSL, create and manage files and diagrams on the canvas, and retrieve aggregated usage metrics.
