# ## Let's play with JSON to access **the NARA Catalog Morgenthau Diaries** Series: 
# ### - we use an API call where we specify a NARA Series ID directly: 589213
# ### - API Call: <https://catalog.archives.gov/api/v2/records/search?q=*&abbreviated=true&limit=200&title='Diaries'&naId=589213>

# ### - Using Python to talk to NARA's Catalog through API calls:

# In[33]:


import requests
import json


# In[35]:


#LISTING the 'Diaries of Henry Morgenthau, Jr.' Series, totalling over 850 volumes 
response = requests.get("https://catalog.archives.gov/api/v2/records/search?q=*&abbreviated=true&limit=200&title='Diaries'&naId=589213", 
                        headers={"Content-Type": "application/json", 
                                 "x-api-key": "API-KEY"})

# If you take a look at the response, you’ll see that it is actually serialized JSON content
# The following command will display the content in JSON format
data = response.json()
with open('data.HMJr.json', 'w') as f:
    json.dump(data, f)
