Dowloading data from quandl.com and want to know how I include my API key with my request?
<p>I am downloading data from quandl.com with python and I have reached my limit with 50 downloads for today. Users with an account can exceed this limit which I already have an account set up. The error message say I need to put my api key with the request, but to my knowledge it does not say how??  </p>

<p>This is the error message </p>

<pre><code>quandl.errors.quandl_error.LimitExceededError: (Status 429) (Quandl Error QELx01) You have exceeded the anonymous user limit of 50 calls per day. To make more calls today, please register for a free Quandl account and then include your API key with your requests.
</code></pre>

<p>This is the code I am using it works except for request limit</p>

<pre><code>import quandl
import pandas as pd
from datetime import datetime
import pandas.io.data as web

symbols = ['BOE/XUDLTWD','BOE/XUDLCDS','tvix'] 



pnls = {}
for i in symbols:

    a = '/' in i

    if a == True:
        data = quandl.get(i ) 
        t = i.split('/')
        df1= pnls
        df1[str(t)] = data
        print(a)
</code></pre>
