curl -X POST https://www.ffmpegapi.net/api/video_loop -H 'Content-Type: application/json' -d '{"video_url": "https://example.com/clip.mp4", "number_of_loops": 3}'
import requests

url = "https://www.ffmpegapi.net/api/video_loop"
data = {"video_url": "https://example.com/clip.mp4", "number_of_loops": 3}
response = requests.post(url, json=data)
print(response.json())
