  title: Bannerbear Animated GIFs Images API
  description: The Bannerbear API auto-generates images and videos from reusable templates. A request applies an array of modifications (text, image, and color layer changes) to a template and renders the output. Most create operations are asynchronous, returning 202 Accepted; results are delivered via webhook callback or retrieved by polling the resource endpoint. Synchronous variants are available on the sync host for images, collections, and screenshots.
