Hi Veronica, 

You can pull the block group data from the Census' API for ACS data, although you'll have to go county by county.  Here's an example to get basic median household income from table B19049 for Antagua County, AL (fips: 01001):

https://api.census.gov/data/2018/acs/acs5?get=NAME,group(B19049)&for=block%20group:*&in=county:001&i...

Essentially the request is for all of table B19049, blockgroup is wildcard, or all block groups, denoted by (*), within the county of interest.

For more info, you can look at the Census Data API User Guide: https://www.census.gov/content/dam/Census/data/developers/api-user-guide/api-guide.pdf
