curl -X POST https://www.ffmpegapi.net/api/add_subtitles \n-H "Content-Type: application/json" \n-d '{"video_url": "https://example.com/video.mp4", "subtitle_url": "https://example.com/subtitles.ass", "async": false}'
import requests\n\nurl = 'https://www.ffmpegapi.net/api/add_subtitles'\ndata = {\n    'video_url': 'https://example.com/video.mp4',\n    'subtitle_url': 'https://example.com/subtitles.ass',\n    'async': False\n}\n\nresponse = requests.post(url, json=data)\nprint(response.json())
