Text-to-Video API
Generate video from text prompts through one API — leading video models from multiple providers behind a single key, priced per second of output video so you can compare real costs before you commit.
9 text-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.

How much does a text-to-video API cost?
Text-to-video models are typically priced per second of generated video (some by resolution tier), and the exact per-model rates are listed in the table above. A short clip costs its duration times the per-second rate — there are no minimum fees or subscriptions.
How do I call a text-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 text-to-video models from Claude or Cursor?
Yes. Connect the ModelRunner MCP server (https://mcp.modelrunner.run/mcp) once and every text-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.
