When to use the API
Reach for the API when you’re building automation: ingesting channel archives into a vector DB, generating SRT files at scale (YouTube only — it’s the platform that returns per-line timing), indexing video courses, or wiring transcripts into an LLM pipeline. If you just need to grab a single transcript, the no-code tools on the main site are faster.Supported platforms
