description: Leonardo.AI is an Australian generative-AI company (acquired by Canva in July 2024) offering a
  Production API for AI image generation, video generation, 3D model creation, custom model and element training,
  realtime canvas editing, upscaling and variations, and Blueprint workflow execution. The platform supports
  in-house Leonardo models (Phoenix, Lucid Origin, Lucid Realism) and third-party models (FLUX.1/FLUX.2, Ideogram
  3.0, GPT Image, Nano Banana, Seedream, Kling, LTX, Veo, Seedance, Hailuo, Rodin) under a unified pay-as-you-go
  dollar-denominated API surface with webhook callbacks, MCP server integration, and official Python and
  TypeScript SDKs.

  name: Leonardo.AI Image Generation API
  description: Create image generations with FLUX.2 Pro, FLUX Dev, FLUX Schnell, FLUX.1 Kontext, Phoenix,
    Lucid Origin, Lucid Realism, Ideogram 3.0, GPT Image 2, Nano Banana, Seedream, and other supported models.
    POST /generations submits a job; results are retrieved via GET /generations/{id} or via the optional
    webhook callback. Supports PhotoReal, Alchemy, image prompts, image guidance (ControlNet), enhanced prompts,
    transparency, and per-model knobs.
