Image-to-Video API
Animate still images into video through one API — start from a reference frame, control motion with a prompt, and pay per second of output across every image-to-video model in the catalog.
13 image-to-video models available right now — every one runnable in a free playground, through the REST API and JavaScript SDK, or from an AI assistant via MCP.

Call a image-to-video model in one request
Every model shares the same request lifecycle: submit to the queue, poll the status URL, fetch the result. Swap the endpoint to switch models — nothing else changes.
cURL
curl -X POST https://queue.modelrunner.run/kuaishou/kling-video/v2.1-master/image-to-video \

-H "Content-Type: application/json" \
-d '{ "input": { "prompt": "..." } }'
# → { "request_id": "...", "status_url": "...", "response_url": "..." }Use image-to-video models from Claude & Cursor
Connect the ModelRunner MCP server once and your AI assistant can run every image-to-video model in this table as a tool — authorized via OAuth, results returned as hosted URLs in the conversation.

How does an image-to-video API work?
You submit an image URL (upload local files via the Storage API first) plus an optional motion prompt; the model returns a hosted video URL. Requests run asynchronously through a queue — submit, poll status, fetch the result — or in one call with the JavaScript SDK’s subscribe().
How do I call a image-to-video model via the API?
Every model shares the same request shape: POST https://queue.modelrunner.run/<owner>/<alias> with an Authorization: Key header and an {"input": {...}} body, then poll the returned status_url and fetch the result from response_url. The JavaScript SDK (@modelrunner/client) wraps this in a single subscribe() call. Each model page shows copy-paste cURL, JavaScript, and Python examples with that model's real inputs.
Can I run image-to-video models from Claude or Cursor?
Yes. Connect the ModelRunner MCP server (https://mcp.modelrunner.run/mcp) once and every image-to-video model in the catalog becomes a tool your AI assistant can call with the run_model tool — authorized via OAuth, no API key pasted into config.
