Convert API response to Data Frame - json

Question

I have been trying to get data from an API and convert it to a Pandas DataFrame.
However, after reading the data from the API, I'm unable to convert the response to JSON.
import pandas as pd
import numpy as np
import requests
import json
r = requests.get('https://api.rootnet.in/covid19-in/')
x = r.json()
print(type(x))
df = pd.DataFrame(x['teams'])
df
error:
JSONDecodeError Traceback (most recent call last)
<ipython-input-13-e2dd33599256> in <module>()

6 r = requests.get('https://api.rootnet.in/covid19-in/')
----> 7 x = r.json()
8 print(type(x))
9 df = pd.DataFrame(x['teams'])
