Utilizing this API eliminates the need for extensive video editing software and infrastructure, streamlining your workflow significantly.

  • Transcribes audio and generates captions.
  • Provides styled captions suited for TikTok.
  • Returns caption artifact URLs for further use.

How to Use the AI Captions Endpoint

To use the AI Captions endpoint, you need to send a POST request with the required parameters. The key parameters include the video URL and optional parameters such as subtitle style and language preferences.

Here is a practical example of how to call the API using cURL and Python.
