Quick Start: Integration Code
Google Gemini API (Python)
import google.generativeai as genai
genai.configure(api_key="YOUR_API_KEY")
model = genai.GenerativeModel('veo-3.1-fast-generate-preview')
response = model.generate_content({
'prompt': 'A cat playing piano, close-up shot',
'duration': 8,
'resolution': '1080p',
'aspect_ratio': '16:9'
})
video_url = response.video_urlVeo3Gen API (Simpler - Any Language)
// JavaScript / Node.js
const response = await fetch('https://api.veo3gen.app/v1/generate', {
method: 'POST',
headers: {
'Authorization': 'Bearer YOUR_API_KEY',
'Content-Type': 'application/json'
},
body: JSON.stringify({
prompt: 'A cat playing piano, close-up shot',
duration: 8,
resolution: '1080p',
aspectRatio: '16:9'
})
});
const data = await response.json();
const videoUrl = data.video_url;Rate Limits & Best Practices
Google API Limits

- • Cache results when possible
- • Use webhooks for async processing
- • Monitor API usage and costs
❌ Don't:
- • Hardcode API keys in frontend
- • Ignore rate limit headers
- • Skip error handling
- • Generate unnecessarily long videos
Authentication & Security
Google API Authentication
# Requires Google Cloud Service Account export GOOGLE_APPLICATION_CREDENTIALS="path/to/key.json" # Or use API key genai.configure(api_key="YOUR_GOOGLE_API_KEY")
Veo3Gen API Authentication (Simpler)
# Simple Bearer token
curl -X POST https://api.veo3gen.app/v1/generate \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"prompt": "A sunset over mountains"}'✓ No OAuth, service accounts, or complex setup needed
Monitoring & Debugging
Common Errors & Solutions
❌ Error: Rate limit exceeded
Solution: Implement request queuing or upgrade API tier
HTTP 429 - Too Many Requests⚠️ Error: Invalid prompt
Solution: Check content policy, avoid prohibited terms
HTTP 400 - Bad Request🕐 Error: Generation timeout
Solution: Use async endpoints, implement proper timeout handling
HTTP 504 - Gateway TimeoutStart Building with Veo 3.1 API
