  • Verify Base URL is exactly https://api.lemondata.cc/v1
  • Check for trailing slashes (remove if present)
  • Verify internet connectivity and firewall settings
  • Double-check your API key
  • Verify the key is active in LemonData Dashboard
  • Ensure no extra spaces in the key
  • Check your account balance in the dashboard
  • Add credits to your account
  • Verify model name is spelled correctly
  • Check model availability at lemondata.cc/en/models
  • Try a different model
  • Try a faster model (e.g., gpt-4o-mini instead of gpt-4o)
  • Reduce max_tokens parameter if available
  • Check your network connection

​
Tips

Match the model to your task - use GPT-4o-mini for quick chats, Claude or GPT-4o for complex tasks.
Most apps support saving prompts or personas. Create templates for common tasks.
Check your usage in the LemonData dashboard to track costs and manage your budget.
