Google Civic Information API Integration
The Google Civic Information API is the gold standard for:
- Address-to-representative mapping
- Elected officials contact information
- Election data and polling locations
- Voter information
API Docs: https://developers.google.com/civic-information
Free Tier: 25,000 requests/day
Cost: Free for non-commercial use
SETUP:
1. Get API key: https://console.cloud.google.com/
2. Enable "Google Civic Information API"
3. Add to .env: GOOGLE_CIVIC_API_KEY=your-key
USAGE:
from discovery.google_civic_integration import GoogleCivicAPI
api = GoogleCivicAPI()
# Get representatives for an address
reps = await api.get_representatives("1600 Pennsylvania Ave NW, Washington DC")
# Get upcoming elections
elections = await api.get_elections()
# Get voter info
voter_info = await api.get_voter_info("123 Main St, Tuscaloosa, AL")
