API related issues

When I try to see top 4 results of any keyword in my website https://topimagesites.com/ where I have used pond5 api. Then these 4 images are different than the first 4 image results I see in the pond5 website with the same keyword. What I want is the first 4 results I see in the pond5 website, I should be able to see them in my website as well.

Check these two screenshots, first of my website https://topimagesites.com/ and second of https://www.pond5.com/photos/1/beatle.html , when I tried the keyword "beatle"

It should show the results of the original searched word in the first place right? Because what I need is beatle and not beetle. And this option of correcting it is available in pond5 website. But it's not available in my website where I have used the api.
So on my website it would show the wrong keyword only. And there is no option to correct.

How to go around that issue.
