I've been using the GetSearchResults web service and it has suddenly stopped working because it's asking me to respond to a Captcha, which doesn't make any sense because it's an API so it shouldn't be asking for human response.
This code is running in Google App Engine. On localhost it works fine, but fails in production.
Below shows what my code is trying to fetch. The is HTML that is coming contains a Captcha. I should be getting XML back instead. What's going on?
