⚙️ Technical Details

API Integration

This server uses the unofficial Municode API with endpoints including:

• State and municipality discovery

Data Structure

Municipal codes are organized hierarchically:

Each municipality may have multiple products (Code of Ordinances, Zoning Ordinance, etc.), each with its own hierarchical structure.

⚠️ Limitations

• Uses unofficial API endpoints that may change

• Not all municipalities have all features available

• Some content may be in PDF format and not searchable via API

• Rate limiting may apply to API requests

• Municipality names must match Municode's exact formatting
