find_brand_locationsLook up gas-station locations for a major US fuel brand (Buc-ee's, Costco, Sam's Club). Optionally filter to one state by 2-letter code. Returns city, state, ZIP (when known), and warehouse count for warehouse chains.
get_national_averageGet the current US national average retail gasoline price in dollars per gallon, sourced from the EIA weekly retail series and cached for 24 hours.
get_state_averageGet the current average retail gasoline price for a US state. Returns dollars per gallon and a freshness/source indicator. States without their own EIA series fall back to their PADD region average.
