Instagram Transcription API for Reels

Add Instagram video transcription to a backend with one asynchronous REST endpoint. Send a public Reel or video URL, receive a polling location, and retrieve structured transcript text with timestamped segments.

Transcribe Instagram media without maintaining a downloader

Instagram media ingestion changes over time and can become a maintenance burden. Fast Transcriber handles the supported public-link resolution and speech-to-text pipeline behind one authenticated request, so your application can focus on the transcript and the workflow built around it.

Choose the right public Instagram Reel or video URL

Reels: use the copied instagram.com/reel/{shortcode} or instagram.com/reels/{shortcode} URL for a public Reel.
Video posts: an instagram.com/p/{shortcode} URL works when the post contains one public video; image-only posts have no speech to transcribe.
Legacy video links: instagram.com/tv/{shortcode} links can be submitted when the video remains publicly available.

Quickstart: queue a public Instagram Reel or video transcription

Create a Fast Transcriber API key and store it in a server-side environment variable. Send the public media URL as source_url; never expose the Bearer key in browser code or commit it to source control.

curl --request POST https://fast-transcriber.com/api/v1/transcriptions \
  --header "Authorization: Bearer $FAST_TRANSCRIBER_API_TOKEN" \
  --header "Content-Type: application/json" \
  --data '{
    "source_url": "https://www.instagram.com/reel/C0Example123/",
    "speaker_diarization": false
  }'

A valid request returns 202 Accepted. This means the job was queued, not that the source was fetched successfully. Read the Location response header, set LOCATION_PATH to that path, and poll it until the job status is completed or failed.

LOCATION_PATH="/api/v1/transcriptions/95c3fdd8-..."
curl --request GET "https://fast-transcriber.com$LOCATION_PATH" \
  --header "Authorization: Bearer $FAST_TRANSCRIBER_API_TOKEN"

Work with text and timestamped segments

Completed jobs contain the transcript text and timestamped segments available under the authenticated account's plan limits. The same response shape lets an application index a video, jump to quoted moments, create summaries, or feed the transcript into an authorized search or RAG workflow.

{
  "data": {
    "id": "95c3fdd8-...",
    "filename": "source-video.mp4",
    "status": "completed",
    "duration_seconds": 84,
    "text": "Completed transcript text...",
    "segments": [
      { "start": 0, "end": 3.8, "text": "First segment..." }
    ]
  }
}

Set speaker_diarization to true when speaker labels are needed. Speaker diarization requires a Pro account and uses the same account limits as the web application.

What developers build with public Instagram Reel or video transcripts

Creator archives: store searchable text alongside public Reels your application is authorized to index.
Content review: route spoken claims, campaign messages, or creator submissions through a text-based review process.
Repurposing workflows: turn approved video speech into briefs, captions, quotes, or draft copy while preserving timestamps.

Supported links and access requirements

The API supports public Instagram Reel and single-video post URLs that the link resolver can open without an Instagram session.

The Reel or video post must be public and available without signing in.
Private profiles, close-friends posts, removed media, and login challenges cannot be imported by URL.
Instagram availability and rate limits can occasionally block an otherwise public URL; handle a failed job and offer an authorized upload fallback.
For carousel posts, use a direct single-video post or upload the specific video you are authorized to process.

If a recording is private and you are authorized to process it, retrieve the media through your own authenticated workflow and use the direct audio and video upload API instead.

Troubleshoot public Instagram Reel or video imports

Test signed-out access: open the exact Reel or post in a private browser window. A login wall usually means the worker cannot fetch it either.
Treat carousel media explicitly: do not assume a post URL selects every slide. Upload the exact authorized video when a carousel contains multiple assets.
Handle platform access failures: an Instagram rate limit or access challenge can fail after the job is queued. Back off and offer a direct-upload fallback instead of retrying forever.

Plan for asynchronous errors

Production integrations should handle invalid or inaccessible sources, authentication failures, account limits, and temporary processing failures. Immediate HTTP failures use an {"error":{"code":"...","message":"..."}} envelope. A queued source can later return data.status as failed with details in data.error when polled. Do not retry private, removed, or login-gated media indefinitely; surface a clear message or offer an authorized file-upload fallback.

Frequently asked questions

Which Instagram links can the API transcribe?

Public Instagram Reel and single-video post URLs that open without signing in can be submitted as source_url.

Can the API transcribe private Instagram content?

No. If you are authorized to use private media, download it through your own authenticated workflow and use the direct-upload API.

Does the POST request return the finished transcript?

No. It returns 202 Accepted and a Location header. Accepted means queued, not successfully fetched; poll that URL until the job completes or fails.
