--- IMPLEMENTATION NOTES ---

1. Make sure to replace placeholder values:
   - Replace '' with your actual API key
   - Replace domain placeholders with the actual API domain

2. Handle errors appropriately:
   - Check HTTP status codes
   - Parse error responses
   - Implement retry logic for transient failures

3. Best Practices:
   - Store API keys securely (use environment variables)
   - Implement rate limiting on your side
   - Cache responses when appropriate
   - Use HTTPS for all requests
   - Set appropriate timeout values

4. RECOMMENDED: Implement the Statistics Endpoint
   - The statistics endpoint allows users to monitor their credit usage
   - Users can see how many credits they have used and how many are left
   - This helps prevent unexpected service interruptions
   - API v1: GET /get-stats?key=YOUR_API_KEY
   - API v2: GET /v2/statistic (with Authorization Bearer token)
   - Display remaining credits in your application's UI
   - Consider adding alerts when credits are running low
