The Google Civic Information API provides US-focused civic data — elected officials, polling locations, election information, and political divisions — keyed by postal address or OCD division identifier. It is widely used by civic-tech apps, voter-engagement tools, and journalism projects to surface representatives and ballot information for a given address. The API is small (six endpoints) but covers the main lookups needed for representative info and election day support.

Use Cases

Patterns agents use Google Civic Information API API for, with concrete tasks.

★ Voter Engagement Tooling

Civic-tech and advocacy apps power 'find your representative' and 'find your polling place' features by calling the representatives.representativeInfoByAddress and elections.voterInfoQuery endpoints with the user's home address. The responses include officials by office, contact channels, polling place details, and the contests on the ballot. Most apps cache responses for the duration of an election cycle.

Call /civicinfo/v2/representatives?address=1600+Pennsylvania+Ave+Washington+DC and return the names and contact channels of all federal officials returned.

Newsroom Election Day Support

Newsrooms and political journalism projects use elections.electionQuery and elections.voterInfoQuery to power election-day live tools — lookup widgets that show readers what's on their ballot and where to vote. The API returns structured contest, candidate, and polling-location data, which feeds into custom rendering on newsroom sites.

Call /civicinfo/v2/voterinfo?address=350+5th+Ave+New+York+NY for the next election and return the polling location and the list of contests.

Address-to-Division Resolution

Civic data products map a postal address to the full set of political divisions it falls into — federal congressional district, state legislative districts, county, municipality — using divisions.queryDivisionByAddress. This is the resolution layer that powers 'who represents me' tools and constituent-services CRMs. Each response is a single API call.

Call /civicinfo/v2/divisionsByAddress?address=1600+Amphitheatre+Pkwy+Mountain+View+CA and return the OCD division ids of every division covering the address.

AI Agent Civic Assistant via Jentic

An AI agent through Jentic acts as a civic assistant — taking a street address and returning a plain-language summary of the user's representatives, the next election, and the polling place. Jentic isolates the API key so the agent never holds the raw key string.

Through Jentic, search civicinfo_representative_info_by_address, load schema, and execute it for the supplied address returning a list of officials by level.

Key Endpoints

6 endpoints — the google civic information api provides us-focused civic data — elected officials, polling locations, election information, and political divisions — keyed by postal address or ocd division identifier.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Google Cloud API keys are stored encrypted in the Jentic vault (MAXsystem). Agents call Civic Info with scoped access — the raw API key string never enters the agent's context.

Intent-based discovery

Agents search Jentic by intent (e.g. 'find my US representative by address') and Jentic returns the representatives.representativeInfoByAddress operation with its parameter schema.

Time to first call

Direct integration: 0.5 day for project setup, API key creation, and address validation. Through Jentic: under 30 minutes — search, load, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Complementary

Google Places API

Resolve and validate addresses or look up nearby polling places by location.

Use Places to standardise the address; use Civic Info to resolve representatives and elections for that address.

Alternative

Google Custom Search API

Free-text search across the web rather than structured civic data.

Choose Custom Search for general lookups; choose Civic Info when you need structured representative or election fields.

Complementary

YouTube Data API

Surface candidate and elected official video content alongside Civic Info data.

Pair with Civic Info when an app enriches representative profiles with media.

FAQs

Specific to using Google Civic Information API API through Jentic.

What authentication does the Civic Information API use?

It uses a Google Cloud API key passed as the key query parameter. No OAuth is required because the data is public US civic information. Through Jentic, the API key is stored encrypted in the Jentic vault and the agent calls the API without ever holding the raw key value.

Can I look up a representative by address?

Yes. GET /civicinfo/v2/representatives?address=<address> returns officials at federal, state, and local levels along with contact channels (phones, urls, email, social handles). The address must be a US address; international addresses are not supported.

What are the rate limits for the Civic Information API?

Google enforces a default of 25,000 queries per day per project on civicinfo. Higher quota can be requested via the Google Cloud console. Most applications cache representative lookups by address since the underlying data changes only between elections.

How do I get voter info for an address through Jentic?

Use the Jentic search query "google civic voter information" to discover the elections.voterInfoQuery operation, load its schema, and execute it with the address and optionally an electionId. Run pip install jentic to get started.

Does the API cover non-US elections?

No. The Civic Information API covers only United States civic data — federal, state, and local. For other countries, this API is not the right source.

Is the Civic Information API free?

Yes, the API is free within the default project quota. The underlying civic data is sourced from public records and partner providers and made available without charge.
