Why does TheyWorkForYou (TWFY) web API always returns '{}'
<p>I'm calling a web API exposed by TheyWorkForYou (TWFI).
<a href="http://www.theyworkforyou.com/api/" rel="nofollow">http://www.theyworkforyou.com/api/</a></p>

<p>I'm using the Python bindings provided by twfython:
<a href="http://code.google.com/p/twfython/" rel="nofollow">http://code.google.com/p/twfython/</a></p>

<p>I wrote some code to call this API a few months ago, at which time it worked fine. But now I dig it out to run it again, no matter what query I ask of the API, it always returns '{}' (an empty dictionary). For example the following code, which should return a list of all MPs:</p>

<pre><code>from twfy import TWFY
API_KEY = 'XXXXXXXXXXXXXXXXXXXXXX'
twfy = TWFY.TWFY(API_KEY)
print twfy.api.getMPs(output='js')
</code></pre>

<p>Am I being really dumb? What else should I check?</p>
