	Description		Read-only	Idempotent	Open world
`get_demographic_indicators`Get demographic vulnerability indicators by block group. Returns demographic data including minority percentage, low income percentage, linguistic isolation, education levels, and age distributions. These are the demographic components used in EJScreen's EJ index calculations. Args: state: Two-letter US state abbreviation (e.g. 'WA', 'CA'). county_fips: Optional county FIPS code (3-digit or 5-digit). If omitted, returns state-level results sorted by highest demographic index. limit: Maximum number of block groups to return (default 50, max 500).

`get_ej_county_summary`Get EJ indicators for census block groups in a county. Returns EJScreen environmental justice data for block groups within the specified county, sorted by highest overall environmental burden. Includes environmental indicators, demographic data, and EJ indexes. Args: state: Two-letter US state abbreviation (e.g. 'WA', 'CA'). county_fips: County FIPS code, either 5-digit full (e.g. '53033') or 3-digit county portion (e.g. '033').
