Perplexity

Get Full County Economic Snapshots

The `get_county_profile` tool pulls a complete socioeconomic picture for any county. It delivers population metrics, income levels, and housing data in one go. Your UI streams the results instantly. When the user asks about market potential, you call `get_county_profile` and show the numbers appearing live, avoiding that dreaded loading spinner.

Analyze State-Wide Demographics

Need to segment a market? Use `get_demographics_by_state` for racial and ethnic data across all states. This lets you map diversity patterns quickly. Your agent client streams this demographic breakdown directly into the React component. The end user sees White, Black, Asian, etc., percentages populating in real-time as the API call resolves.

Run Custom Census Queries

The `query_census` tool is your escape hatch for any variable or geography. It lets you run deep custom queries against specific ACS datasets. If a user asks about educational attainment in a niche area, calling `query_census` sends the variables and filters to your agent client. The data appears live, making the AI interaction feel incredibly snappy.
