I spent lots of time to get the results of search engines for my desired keywords. This API provides a package of the most popular search engines in your application. I think the most important feature of this API is gathering the results of different search engines and enable you to get the website of keyword more confidently.
As an idea for the next update, I need to scrap a list of keywords and do it as a batch call instead of a single call.

I will rate 5 stars for this API and recommend others to get the premium version.
