# ## NARA API Catalog Queries for the WWII War Relocation Authority (WRA):
# 
# For example, you can open a NARA catalog URL that runs an **API Catablog query** showing **all 106 Series** under the records of **RG 210 War Relocation Authority (WRA)**. The query returns JSON data which is displayed in the *jsoneditoronline.org* browser:
# - "https://catalog.archives.gov/api/v2/records/parentNaId/537?parentNaid=537&abbreviated=true&limit=200"
# where NARA ID 537 is the unique ID for RG210.
