AI 요약 및 RAG용 YouTube 성적표를 가져오는 방법

If you’re building AI apps that summarize YouTube videos, power RAG over video content, or generate subtitles, you need reliable transcript text — not browser scraping that breaks every other week.

This guide shows a simple REST approach that returns JSON with timestamps, plain text, or raw timed cues.

Why transcripts matter for AI

• Summarization — feed transcript text to GPT/Claude instead of sending video
• RAG — chunk timed cues into a vector database for semantic search
• Accessibility — build caption tools without manual SRT editing
• Content indexing — search across a channel’s spoken content

Quick start with curl

curl "https://get-youtube-transcript.p.rapidapi.com/transcript?video_id=jNQXAC9IVRw&format=json" 
  -H "X-RapidAPI-Key: YOUR_KEY" 
  -H "X-RapidAPI-Host: get-youtube-transcript.p.rapidapi.com"

Enter fullscreen mode Exit fullscreen mode

Replace YOUR_KEY with a key from the YouTube Transcript API on RapidAPI. The Basic plan includes 100 free requests/month.

Python example

import requests

API_URL = "https://get-youtube-transcript.p.rapidapi.com/transcript"
headers = {
    "X-RapidAPI-Key": "YOUR_KEY",
    "X-RapidAPI-Host": "get-youtube-transcript.p.rapidapi.com",
}
params = {"video_id": "jNQXAC9IVRw", "format": "json"}

data = requests.get(API_URL, headers=headers, params=params, timeout=60).json()

for cue in data["transcript"]:
    print(f"[{cue['start']:.1f}s] {cue['text']}")

Enter fullscreen mode Exit fullscreen mode

Response formats

format Use case json LLM pipelines, metadata + timestamps text Simple summarization raw Subtitle/SRT workflows

Parameters

• video_id — 11-char YouTube ID or pass url with full YouTube link
• languages — comma-separated codes, e.g. en,pt

Production tip

For batch jobs (indexing hundreds of videos), upgrade to the Ultra plan on RapidAPI — 100k requests/month at $9. Test in the playground first with any public video ID.

Disclosure: I built this API. Feedback welcome — especially on languages, latency, and batch endpoints.
