Accessing Google Search Blog with Yahoo Pipes

[Jose Llinares]

Hi guys;

I am working with Yahoo Pipes and I am trying to search the Google
Blog Search with it.

But it seems I am not allowed, I get this error;

warning error fetching http://blogsearch.google.com/blogsearch_feeds?scoring=d&q=keyword&output=rss&lr=lang_es&ie=utf-8
(403 Forbidden)

Is there anyway to access it? a parameter or something? Has anyone
solved this problem?

Thanks in advance and regards
