Caption-first transcript path
Scority starts from accessible YouTube caption tracks where available and keeps the public API response focused on text, segments, source and language.
YouTube Transcript API infrastructure for AI apps
Scority builds the transcript layer that AI products need before they can summarize, search, classify or answer questions about video. The public API focuses on caption extraction, timestamped segments, language selection, fallback infrastructure and server-side access.
What Scority does
Scority is not a broad YouTube platform API. It is a focused transcript API for applications that need clean source text, structured segments and reliable error handling around public videos.
- GET /v1/youtube/transcript on api.scority.ai
- x-api-key authentication for server-side requests
- video_id and video_url request support
- language-aware transcript cache buckets
- timestamped segments for search, RAG and agent tools
- normalized errors for missing transcripts and upstream failures
- fallback processing available for supported accounts
- proxy/captcha routing for difficult upstream access
Engineering layer
The production path is caption-first, with fallback infrastructure available for supported accounts. The engineering layer includes API workers, caption track parsing, language-aware cache buckets, proxy/captcha routing, GPU-capable processing capacity, health checks and usage logging.
Operational controls
API keys, monthly quota, short-window rate limits, health endpoints and usage logging are part of the production foundation.
Fallback infrastructure
Supported accounts can use proxy/captcha routing and GPU-capable fallback processing for harder videos, while the API still avoids every-video guarantees.
Caption pipeline
Request validation, caption selection, parsing and normalized transcript output.
API operations
Health checks, usage logs, quota state and rate-limit headers for production clients.
Fallback workers
Proxy/captcha routing and GPU-capable capacity for account-specific processing paths.
