Leonardo.AI

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.

List Leonardo platform models (Phoenix, Lucid, FLUX, Ideogram, etc.) and manage custom fine-tuned models. Includes model catalog, custom model training, retrieval, and deletion ...

Leonardo.AI Elements API

Create and manage Custom Elements — LoRA-style style adapters trainable on user datasets and reusable across image generations to enforce visual identity, style, or character co...

Leonardo.AI Datasets API

Create, upload to, and delete training datasets used as input to custom model and element training. Upload images directly or from existing generations.

Leonardo.AI Init Images API

Upload, retrieve, and delete init images used for image-to-image, image-prompt, canvas, and image-guidance workflows. Returns presigned upload URLs.

Leonardo.AI Media API

Upload, retrieve, and delete general-purpose media (images, video frames, reference assets) used across generation endpoints.

Leonardo.AI 3D Model Assets API

Upload, retrieve, and delete 3D model assets — used with Rodin V2 and other 3D-capable workflows for texturing and generation.

Leonardo.AI Blueprints API

Execute Leonardo Blueprints — pre-packaged multi-step image and video workflows authored in the Leonardo App — and retrieve their executions, generations, and version history. L...

Leonardo.AI Prompt API

Improve user-supplied prompts with the Prompt Improvement endpoint and generate random prompts for inspiration. Used to bootstrap and refine generation requests.

Leonardo.AI Pricing Calculator API

Pre-calculate the API credit cost (in USD) of a generation request before submitting it. Mirrors the cost estimation logic of the in-app Pricing Calculator.

Leonardo.AI User API

Retrieve the authenticated user's profile, subscription info, and remaining API credit balance via GET /me. Used as the canonical balance-check endpoint for FinOps reporting.
