How to unnest json data to dataframe using python

Question

import json
import pandas as pd

resp = requests.get('https://data.cms.gov/provider-data/api/1/datastore/query/77hc-ibv8/0?offset=0&count=true&results=true&schema=true&keys=true&format=json')
data = resp.json()
data = json.dumps(resp_dict,indent=4)
print(data)

I am trying to unnest the json data into a dataframe using Python. There are a few ways to do it but wasn’t able to fully unnest the json data. What would be the best way to accomplish this?

Nothing special just pass it to pd.DataFrame and refer to the main key.

import json

import pandas as pd

import requests


def get_data() -> pd.DataFrame:
    url = (
        "https://data.cms.gov/provider-data/api/1/datastore/query/77hc-ibv8/0?"
        "offset=0&"
        "count=true&"
        "results=true&"
        "schema=true&"
        "keys=true&"
        "format=json"
    )

    with requests.Session() as request:
        response = request.get(url, timeout=10)
    if response.status_code != 200:
        print(response.raise_for_status())

    data = json.loads(response.text)

    return pd.DataFrame(data=data["results"])


print(get_data())
