Error Handling

Common scenarios to handle:

• Invalid or non-existent Farcaster username/FID
• Address not associated with any Farcaster profile
• Missing optional metadata fields

Best Practices

1. Cache profile data to minimize API calls
2. Implement proper error handling for all resolution methods
3. Always check for null values in optional metadata fields
4. Use the most appropriate resolution method based on your use case:
   • Use farcasterProfile query when you have a Farcaster FID or username
   • Use account query when you have an Ethereum address
5. Consider implementing retry logic for failed queries
6. Keep your cached data fresh with regular updates
