How do I crop image after loading from url?

So I send a post request to a url and get an image url back. Now I load image from that url for a sprite. The problem is that the image that is sent back doesn't have transparent edges cropped. Is there way to do that through events after loading the image from the url? I want it to have the same effect as "Crop Transparent Edges" in the image editor. Please tell me if there's a way to do this.

Most of the editor features are not available at runtime. So no, there is no feature out of the box to do that AFAIK.
