YouTube Transcript API Alternative
Compare official APIs, open-source libraries, and managed transcript APIs for YouTube transcript workflows without assuming every video is available.
A transcript API is useful when transcripts are the product task
If you only need video metadata or platform operations, the official YouTube Data API is often the right starting point. If your app needs transcript text and timestamped segments for AI workflows, a transcript-specific API can be a better fit.
- Scority exposes GET /v1/youtube/transcript for server-side transcript requests.
- Requests can use video_id or video_url, plus an optional language parameter.
- Responses include text, segments, source, and language.
- Some public videos do not have accessible captions, so transcript_not_available and upstream_transcript_failed remain real outcomes.
Use the official YouTube Data API
The official YouTube Data API is the right tool for many YouTube platform operations. It is not the same thing as a general transcript extraction API for public videos.
Less direct fit
Applications that primarily need transcript text and timestamped caption segments from public videos.

Open →Use an open-source transcript library
Open-source libraries can be enough for local experiments, small scripts, and teams comfortable owning breakage, retries, hosting, and error handling.
- A library can be a good fit when you control runtime, volume, and maintenance.
- A managed API can be a better fit when you need server-side auth, normalized errors, OpenAPI documentation, quota, and usage logs.
- Do not assume a library or a managed API will return a transcript for every video.
Use Scority for a focused transcript workflow
Scority is designed around the transcript request itself. The current public API is intentionally narrow and does not pretend to cover dashboard, billing, upload, search, or channel operations.
Current endpoint
GET /v1/youtube/transcript at https://api.scority.ai.
Open →Authentication
Use x-api-key from server-side code. Do not put keys in browser bundles.
Open →Errors
Handle unauthorized, invalid_video_id, rate_limited, quota_exceeded, transcript_not_available, and upstream_transcript_failed.
Open →Where the product boundary is
Scority does not claim to be Google's official API, does not guarantee that every video has accessible transcripts, and does not expose a public web proxy at /api/transcript.
- The stable public integration path is the HTTP API and OpenAPI specification.
- API keys are issued for server-side use and should never be exposed in browser code.
- Some videos return transcript_not_available or upstream_transcript_failed.
- Proxy and speech-to-text fallback behavior should be treated as account-specific engineering, not a default guarantee.
Choose based on operating model
If you want a managed transcript endpoint, start with the API reference and test videos that match your real workload. If you need a broader YouTube product surface, compare official APIs and broader data providers first.
