Perplexity

Get business patterns with guaranteed types.

When you use `get_business_patterns`, the MCP Server response is immediately validated against a schema. This guarantees that every piece of data—establishment counts, employee numbers, or payroll totals—is exactly what your agent expects.

Validate state education metrics.

The `get_education_by_state` tool provides educational attainment levels for all states. Pydantic AI ensures that the output model is correctly typed, preventing silent errors if the API data structure changes.

Process county income metrics safely.

With `get_income_by_county`, you get median household income and poverty rates. If the Census data returns a field we didn't anticipate, Pydantic AI fails loudly with an explicit validation error instead of letting your agent process garbage data.

Type-safe state economic analysis.

For high-level comparisons, call `get_income_by_state`. It returns median household income and poverty rates for all states. The type enforcement means you can trust the structure of the data every single time.
