Census Block Level

Value Historical (Batch)

This endpoint provides a historical time series of monthly block-median data for dollar value and dollar value per sq ft. You can specify a desired property type using the property_type request parameter. The default is SFD. You can also specify the order, limit, start, and end request parameters. The order parameter determines the chronological order to sort result items. The limit parameter sets the maximum integer number of result items to return. The start and end parameters set the beginning and ending date limits for result items, respectively, based on month in ISO 8601 format (e.g., 2015-01-01). Values may go back as far as 1985
