Does it work for videos without captions?

The action works with both auto-generated and manually uploaded captions. Most YouTube videos have auto-generated captions enabled by default. If no captions are available, the action will return an appropriate error message.

How many credits does it cost?

1 credit per run. You can check your remaining credits in the SyncGTM dashboard.

Can I use this action via MCP with AI tools?

Yes. Configure the SyncGTM MCP server in your AI tool (Claude, ChatGPT, Cursor, Windsurf) and you can scrape YouTube transcripts directly from your AI assistant.

Is there a video length limit?

There is no strict length limit. The action handles videos of all lengths, from short clips to multi-hour webinars. Longer videos will return larger transcript payloads.
