"123.456.789-00"
"12345678900"

Error Handling

The system includes comprehensive error handling:

• API connection errors
• Invalid document formats
• Missing API keys
• Rate limiting
• Malformed responses

Troubleshooting

Issue	Solution
API key not found	Set PORTAL_TRANSPARENCIA_API_KEY in .env file
Connection timeout	Check internet connection and API status
No records found	Verify CPF format and check if person exists
401 Unauthorized	Verify API key is correct and active
