  title: Flux Image Editing Results API
  description: REST API for editing and transforming existing images using Black Forest Labs' FLUX.1 Kontext models. The Kontext models accept an input image and a text prompt describing desired edits, returning a modified image. They support context-aware in-painting, object replacement, style transfer, background changes, and image-to-image transformations while preserving important visual context. Authentication requires an API key in the X-Key header. Requests are asynchronous and require polling for results.
