Serel and pilha are good Ruby wrappers for the StackExchange API, but I am not able to access the body method for question and answers. The body method returns nil.

I want the content of questions and answers. How can I get them?

Also I have used Nokogiri to extract content, but sometimes I get an "internal error 500". Why is this so? Do they block the scraper #Nokogiri after some attempts?

Although I don't use Ruby (and consequently have not used the two libraries you've mentioned), I'm going to guess that the problem is that you aren't specifying a filter that includes body.

By default, post body is not included in the JSON returned by API methods and must explicitly be requested by creating a filter that includes it. The withbody filter, for example, would include body in the response.

You will likely want to consult the documentation for each library for instructions on setting a filter.
