Best Practices

⚡ Performance Tips

  • Cache translations for repeated text to leverage our 90%+ cache hit rate
  • Use batch requests for multiple translations
  • Implement connection pooling for high-volume usage
  • Set appropriate timeouts (recommended: 30 seconds)

🔒 Security Best Practices

  • Always use HTTPS for all API requests
  • Store API keys securely (never in client-side code)
  • Implement rate limiting on your end to avoid exceeding quotas
  • Use different API keys for development and production
