Note:

The caption_url field returns a time-limited link that expire after 7 days. The caption file itself does not expire, only the link does. To ensure continuous access, you have two options:

Download the File: Save the caption file locally within the 7-day window.

Regenerate the URL: Call the endpoint again whenever you need to access the caption file. Each time you call the endpoint, the Expires and related query parameters in the URL are regenerated, reflecting the new expiration time.
