Lookup API - Support multiple URLs to test

If there is no option, can you please enhance the API to **support testing multiple URLs** against multiple threadTypes, via a single HTTP or API call?

This way it will significantly improve the **performance** and reduce the **server load** both at the client side API and Google WebRisk service side as well.

Currently, I have a requirement to validate almost 15-20K links per day, sometimes 50-100 new links within a minute, so it is really critical to validate multiple links in one short, as a batch call. Please accommodate this request.
