How does Slazzer’s API work?

Technology is evolving and it’s making things easier for people and
businesses all over the world. Similarly, with the Slazzer API, anyone can now
process millions of images and integrate it in their own project smoothly with
just a single API call. Customize images in REAL TIME and add new
background colors, custom backgrounds or crop the image by pixel. Use the
advanced parameters to customize as per your needs, it’s 100% automatic
and versatile.

Now, you can set a transparent or white background for your product images
and be in an Amazon-like position to sell. With the help of the API, you can
give your users or third party sellers the ability to change the background in
photos instantly. The only requirement is that the product on your photo must
be clearly in the foreground.

How the API Service Works?

You can integrate the open API code of Slazzer in any application or website
to smoothly remove backgrounds in a continuous queue. Slazzer charges 1
credit per output image and prices range depending on the plan. Developers
can now integrate the code any way they want to create mind blowing
experiences the world has never seen.

You can further customize the images by using the Slazzer crop functions to
cut out the transparent pixels only and specifically the crop_margin function to
cut out the output image to your liking. In addition, you can scale any image
(making it any size) and also use the ROI parameter to position the cut out
image subject as you like. The input image can either be a url or a base64 file
format and you can also set the background image either as a file, url or a
base64 string. You can convert the output image to jpg or png and also take
the output image as a url or a base64 format so you can take the preview
images as an output as well.


The Slazzer API parameters are advanced and offer many customizations to
developers. It’s so easy to use and can be flexible to integrate in so many
different situations. Some examples are Ecommerce sites that want to have
third party sellers automatically crop their product images, Photo editing apps
that want to offer their users a background removal option, Online Design
Tools for creating media and banners, Auto Networks that want to place a
custom background on their cars with branding, Consumer Apps that want to
give their clients a way to snap a quick selfie and upload it without a
background, Classified Apps that want to give their users a way to sell their
products with a white background…. as white backgrounds sell better! We
covered this already 😉

The possibilities are endless with the API and any developer in the world can
now use it to really push the boundaries of what is possible in today’s visual
