In fact, you don't need url in there either since it's not 
dependent on loop variables, and you don't need the scope guards 
if this is running in main (you can move them out of the loop 
too).

foreach (...) {
     https.handle.set(CurlOption.url, url);
     https.perform();
     apidata.insert(tuple(seq, cast(string) content));
     content = [];
}
