Wikipedia Integration. How?

If I wanted to import few lines 开发者_Go百科of a document from Wikipedia into my site. How can I do this?

For example if I had a page about Google and I wanted to just import first paragraph about Google directly from Wikipedia is there an API that does this?

MediaWiki does have an API for all of the MediaWiki databases (Including Wikipedia), which can be found on the API page of the MediaWiki website. There is documentation to go along with it, although it seems a bit verbose.
