Rewrite Rule from Apache to Nginx

Question

Can anyone help me with rewriting this? I have these rules:

    RewriteCond %{HTTP_USER_AGENT} baiduspider|facebookexternalhit|twitterbot|rogerbot|linkedinbot|embedly|showyoubot|outbrain|pinterest [NC,OR]
    RewriteCond %{QUERY_STRING} _escaped_fragment_
    RewriteRule ^(?!.*?(\.js|\.css|\.xml|\.less|\.png|\.jpg|\.jpeg|\.gif|\.pdf|\.doc|\.txt|\.ico|\.rss|\.zip|\.mp3|\.rar|\.exe|\.wmv|\.doc|\.avi|\.ppt|\.mpg|\.mpeg|\.tif|\.wav|\.mov|\.psd|\.ai|\.xls|\.mp4|\.m4a|\.swf|\.dat|\.dmg|\.iso|\.flv|\.m4v|\.torrent))(.*) /api/prerender/$2 [P,L]

And I need that to be rewritten to nginx.

Basically, let's assume this URL

http://example.com/?_escaped_fragment_=/item/123

should be rewritten to

http://example.com/api/prerender/?_escaped_fragment_=/item/123

I hope you understand.

Try:

location / { 
  if ($http_user_agent ~* "baiduspider|facebookexternalhit|twitterbot|rogerbot|linkedinbot|embedly|showyoubot|outbrain|pinterest") {   
    rewrite ^/(?!.*?(\.js|\.css|\.xml|\.less|\.png|\.jpg|\.jpeg|\.gif|\.pdf|\.doc|\.txt|\.ico|\.rss|\.zip|\.mp3|\.rar|\.exe|\.wmv|\.doc|\.avi|\.ppt|\.mpg|\.mpeg|\.tif|\.wav|\.mov|\.psd|\.ai|\.xls|\.mp4|\.m4a|\.swf|\.dat|\.dmg|\.iso|\.flv|\.m4v|\.torrent))(.*) /api/prerender/$2 break; 
  } 
}
