Overview

Create an asynchronous text-to-video task with a supported model. Use the returned task ID to retrieve its state, or provide callback_url for terminal delivery.

Quick start

  1. Create an API key and set it as RUNAPI_API_KEY.
  2. Choose a supported model and send a POST request whose body matches that model's schema.
  3. Store the returned task ID, then poll until a terminal state or handle the terminal callback.
