How it works

Three steps to your first transcript

  1. 1

    Get a key

    Create an API key in your TubeScribed account under Settings → API Keys.

  2. 2

    Send a YouTube URL

    POST the tool name and input to one endpoint with your key in the Authorization header.

  3. 3

    Get JSON back

    Receive the transcript or finished asset as clean JSON, ready for your app or workflow.

Tools

Four tools, one endpoint

POST to iblyytktdumianqxfyis.supabase.co/functions/v1/api-v1 with {"tool": "...", "input": {...}}.

transcribe_video

generate_asset

Turns a video or transcript into a blog post, SOP, email sequence, social posts, show notes, FAQ, training guide and more.

Input
asset_type + youtube_url or transcript, optional brand_voice
Returns
The finished asset as text, plus word count

list_asset_types

Returns the full list of asset types with a short description of each.

Input
none

Every output type you can generate

get_usage
