How to submit multiple URLs to crawler API?

I was looking through the crawler API (here) and noticed that the only way to submit multiple links on the host device was through a locally stored file or sitelist via a URL.

I wanted to know if it was possible to submit multiple URLs in a single request. I have an array of URLs that I want to forward to the crawler and looking for the best way to do so.

Simplest way for me would be generating link-list file out of that array and submit that. But maybe there is another solution…
