Transcripts V2

V2 is the streamlined, user-owned transcript model. It prioritizes fast cache hits, consistent responses, and no surprise translations unless you request a language.

New: one mode parameter for every transcript source

Choose auto, captions_only, human_captions_only, speech_to_text_only instead of combining source and allow_asr. Existing requests keep working exactly as before. See how it works

OpenAPI 3.0: V2 (recommended)

Transcribe a single video

The fastest path for one video at a time. Caption-based transcripts return within a few seconds; ASR runs asynchronously and is polled via /api/v2/jobs/{job_id}.

Transcribe a video

Transcribe a single YouTube video. Returns immediately for caption-based videos. With mode=auto it falls back to ASR (async) when captions are unavailable: you get status processing and a job_id to poll at /api/v2/jobs/{job_id}, or the result is POSTed to webhook_url if you set one. Responses include the mode the request ran with.

POST/api/v2/transcribe
Parameters
videostringrequired

YouTube URL or 11-character video ID. Required unless upload_id is set.

upload_idstring

Transcribe an uploaded media file instead of a YouTube video (see /uploads). Forces the ASR path (mode must be omitted or speech_to_text_only); webhook_url required. The upload id is returned as video_id in results.

modeauto | captions_only | human_captions_only | speech_to_text_only

Where the transcript comes from (recommended). auto: captions first, speech-to-text (ASR) only if the video has none. captions_only: any captions, never ASR. human_captions_only: human-made captions only. speech_to_text_only: always transcribe the audio. auto and speech_to_text_only can charge ASR credits. Replaces source + allow_asr; cannot be combined with them. Note: mode=auto is not the same as legacy source=auto (captions only, which is mode=captions_only). When omitted, your account default from the API Dashboard applies: auto for accounts created from October 2026, captions_only for older accounts unless changed. ASR modes work without webhook_url: poll the returned job_id.

languageISO 639-1

Preferred transcript language (e.g. en). If unavailable, captions in another language may be returned: transcript.language reports the actual language.

sourceauto | manual | asr

Legacy, still supported: use mode instead. Default: auto. asr transcribes the audio (async, requires webhook_url).

allow_asrboolean

Legacy, still supported: use mode=auto instead. Falls back to ASR if captions fail.

formatobject

{ timestamp, paragraphs, words }: include extra structure in the transcript.

webhook_urluri

When set, ASR results are POSTed to your URL. Optional with mode (poll the job_id instead); required for legacy source=asr. Ignored by captions_only and human_captions_only, which never use ASR.

asr_optionsobject

Rich ASR config: language (+ codeSwitching, medicalMode, keyTerms), translateTo, speaker diarization (speakerLabels, speakerId + type/known values, multichannel, exact or min/max expected speakers), speech understanding (topics, summary, moderation, PII, profanity, sentiment), and formatting (punctuation, text formatting, filler words, custom date/phone/email patterns). Billable add-ons increase cost: preview with /transcribe/estimate. See the AsrOptions schema in the OpenAPI spec.

Estimate cost

Dry-run credit estimate. Returns the ASR base cost plus any add-on surcharge for the requested asr_options without creating a job or charging credits.

POST/api/v2/transcribe/estimate
Parameters
videostringrequired

YouTube URL or 11-character video ID.

modeauto | captions_only | human_captions_only | speech_to_text_only

Same values as /transcribe. Use speech_to_text_only (or auto) to preview the ASR cost.

sourceauto | manual | asr

Legacy, still supported: use mode instead. Defaults to asr for cost preview.

asr_optionsobject

Same shape as /transcribe. Add-on charges are prorated by duration.

Poll a single transcription job. Use this for ASR jobs returned from /transcribe. Returns 202 while running and 200 when complete. Completed ASR jobs include asr_intelligence (summary, topics, sentiment, etc.) when those options were enabled.

GET/api/v2/jobs/{job_id}
Parameters
job_idpathrequired

Identifier returned in the original transcribe response.

include_segmentsboolean

Include segment-level timestamps in the transcript payload.

}

Upload your own media

Transcribe your own audio or video files through the ASR pipeline. Three steps: register the upload, PUT the bytes to the signed URL, finalize: then call /transcribe with upload_id. Results arrive via your webhook and are polled like any ASR job.

Upload a file

Register an audio/video file upload and get a signed URL. PUT the raw file bytes to signed_url (with the file's Content-Type), finalize via /uploads/{upload_id}/complete, then transcribe with upload_id on /transcribe. Max 2GB and 8 hours per file.

POST/api/v2/uploads
Parameters
filenamestringrequired

Original filename. The extension is preserved for content sniffing.

mime_typestringrequired

Must start with audio/ or video/ (e.g. audio/mpeg, video/mp4).

size_bytesintegerrequired

File size in bytes. Max 2147483648 (2GB).

duration_secintegerrequired

Media duration in seconds. Max 28800 (8 hours). Used for the ASR credit estimate.

curl -X POST https://www.youtubetranscript.dev/api/v2/uploads \
  -H "Authorization: Bearer YOUR_API_KEY" \

  }'

# Then PUT the raw file bytes to the returned signed_url:
curl -X PUT "SIGNED_URL_FROM_RESPONSE" \
  -H "Content-Type: audio/mpeg" \
  --data-binary @interview.mp3

# Then finalize:
curl -X POST https://www.youtubetranscript.dev/api/v2/uploads/UPLOAD_ID/complete \

Response (200)
{
  "upload_id": "up_a1B2c3D4",

  "token": "eyJhbGciOiJIUzI1NiJ9...",
  "signed_url": "https://api.youtubetranscript.dev/storage/v1/object/upload/sign/asr-media/...?token=..."
}

Finish an upload

Finalize an upload after the PUT to signed_url succeeds. Verifies the file exists in storage and marks it ready. The upload can then be transcribed by passing upload_id to /transcribe (source="asr", webhook_url required).

POST/api/v2/uploads/{upload_id}/complete
Parameters
upload_idpathrequired

Upload id returned by POST /uploads.

Transcribe many videos in a single request, then poll or receive results via webhook.

Transcribe many videos

Submit up to 3,000 videos in one request. Returns within 2 seconds; poll the returned poll_url or wait for the webhook.

POST/api/v2/batch
Parameters
video_idsstring[]required

Up to 3,000 IDs depending on plan. Free = 10, Basic = 500, Pro = 1,500, Business = 3,000.

Replaces source + allow_asr; cannot be combined with them. Note: mode=auto is not the same as legacy source=auto (captions only, which is mode=captions_only). For batch, auto and speech_to_text_only require webhook_url. When omitted, your API Dashboard default applies (an ASR default only when webhook_url is set).

Check batch status

Check the status of a batch. Returns 202 while processing and 200 when results are ready. Stop polling once status is "completed", "partial", or "failed": finished batches never change, and re-fetching one more than 60 times in 24h returns 429 with a Retry-After header.

Use a webhook_url to receive results when done.3. GET /api/v2/batch/{batch_id}: poll the batch for overall progress and aggregated results.4. GET /api/v2/channels/{channel_id}: fetch a channel batch with per-video job status; /channels/history lists past channel batches.

List a channel's videos

Maximum uploads returned. Defaults to the plan maximum.

Per-request cap: Basic 500 videos · Pro 1,500 videos · Business 3,000 videos. Monthly job cap: Basic 3 · Pro 8 · Business unlimited.
