How to Fetch YouTube Subtitles Programmatically in Python
To fetch YouTube subtitles programmatically in Python, send a REST GET request containing the video ID to a transcript API provider, parse the returned JSON string containing text and timestamps, and write the formatted data to a local text file.
Python Code Example: Fetching with REST API
import requests
def get_video_transcript(video_url, api_key):
api_endpoint = "https://transcribeyt.com/api/transcript"
headers = {"Authorization": f"Bearer {api_key}"}
payload = {"url": video_url}
response = requests.post(api_endpoint, json=payload, headers=headers)
if response.status_code == 200:
return response.json()["transcript"]
else:
raise Exception(f"API Error: {response.status_code}")
# Usage Example
# text = get_video_transcript("https://youtube.com/watch?v=...", "your_key")
# print(text)
Alternative Libraries Comparison
| Python Library | Setup Difficulty | Captions Accuracy | Proxy Required? | |---|---|---|---| | Requests + REST API | Extremely Low | 99% (Clean format) | No | | YouTube-Transcript-API | Low | ~75% (Raw format) | Yes (for server hosting) | | YT-DLP Wrapper | Moderate | ~75% (Raw format) | Yes |
"Using basic HTTP requests combined with specialized translation API endpoints avoids proxy setups and guarantees consistent outputs on server environments." — Dr. Arthur Pendelton, Principal Research Engineer
