Returns what a YouTube video says, from its captions. The video is identified by its URL or ID.

Request

Exactly one of videoUrl or videoId is required. A request that sets both, or none, fails with invalidRequest.

This endpoint can be called without an API key, subject to per-address limits. Pagination requires a key.

import { Stophy } from "stophy";

const stophy = new Stophy({ apiKey: process.env.STOPHY_API_KEY });
const result = await stophy.youtube.transcript({ videoUrl: "https://www.youtube.com/watch?v=dQw4w9WgXcQ" });
console.log(result.data.text);

from stophy import Stophy

stophy = Stophy()  # reads STOPHY_API_KEY
result = stophy.youtube.transcript(video_url="https://www.youtube.com/watch?v=dQw4w9WgXcQ")
print(result["data"]["text"])

curl -X POST https://api.stophy.dev/v1/youtube/transcript \
  -H "Authorization: Bearer $STOPHY_API_KEY" \
  -H "content-type: application/json" \
  -d '{"videoUrl":"https://www.youtube.com/watch?v=dQw4w9WgXcQ"}'

stophy youtube transcript --videoUrl "https://www.youtube.com/watch?v=dQw4w9WgXcQ"

  },
  "creditsUsed": 1,
  "requestId": "2fe9dbad-fc48-4890-9751-0b24b596035b"
}
