How to get a Utilities file transcript (step by step)

  1. 1

    Get a free API key

    Create a free Captapi account (100 credits, no card) and generate an API key from the dashboard.

  2. 2

    Call the Video File Transcript API

    Send an authenticated POST request to /v1/video/transcript with your input. No OAuth, no scraping setup.

  3. 3

    Read the JSON response

    Parse the clean JSON response. Pass cache=true for a free 24h cache hit; default is always fresh.

Code example

curl -X POST "https://api.captapi.com/v1/video/transcript" \
  -H "Authorization: Bearer capt_live_..." \
  -F "file=@video.mp4"
# or: -H "x-api-key: capt_live_..."

What the response looks like

{
  "success": true,
  "data": {
    "filename": "sample.mp4",
    "transcript": "Hey everyone, welcome back to the channel. Today we're breaking down structured data APIs.",
    "transcriptSegments": [

        "duration": 4.28,

Frequently asked questions

What does the Video File Transcript API do?

The Video File Transcript API lets you extract the full, timestamped transcript from a public Utilities uploaded video or audio file using one POST request to /v1/video/transcript. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the Video File Transcript API cost?

Billing is 1 credit per minute of audio (rounded up, minimum 1). No speech returns an empty transcript with noSpeech=true and 0 credits — the same detection as File Summarizer.

Do I need a Utilities API key or OAuth?

No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, Rumble, Spotify, Kwai, and more. We handle access, rate limits, retries, and authentication for you.

Is the Video File Transcript API suitable for production use?

Yes. It is a stable REST endpoint with predictable JSON. Upload via multipart form field file (POST) — see the cURL sample. Use durationSeconds and durationSeconds to verify per-minute billing. No-speech uploads on File Transcript return noSpeech=true at 0 credits.
