Convert API to Pandas DataFrame

Question

I'd like to convert the API call into a pandas data frame.

At the moment, the API is very unorganised and I'd like to incorporate pandas to make it easier to read/edit/manipulate.

I have attempted the following:

r = requests.get('http://api.football-data.org/v1/competitions/398/teams')
x = r.json()
df = pd.read_json(x)
print df

But receive:

TypeError: Expected String or Unicode

Answer 1

pd.read_json expects a string. However, r.json() returns a dict object.

In your case, you should explore the structure of the returned JSON object by looking at x.keys(). This will yield ['count', '_links', 'teams']. You are probably interested in the 'teams' field.

As such, you should do the following:

r = requests.get('http://api.football-data.org/v1/competitions/398/teams')
x = r.json()
df = pd.DataFrame(x['teams'])
print df

Answer 2

This simple solution worked for me (the api link in question is not accessible by me)

df=pd.read_json('https://api.coinmarketcap.com/v1/ticker/?limit=10')
df.head()
