python

import os
import requests

API_KEY = os.environ["RUNWAY_API_KEY"]
endpoint = "https://api.runwayml.com/v1/gen2/text-to-video"

headers = {
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

payload = {
    "prompt": "A futuristic cityscape at sunset with flying cars",
    "resolution": "720p",
    "duration": 10
}

response = requests.post(endpoint, headers=headers, json=payload)
response.raise_for_status()
video_url = response.json().get("video_url")
print(f"Generated video URL: {video_url}")

output

Generated video URL: https://cdn.runwayml.com/videos/generated/abc123.mp4
