Question 1

What does the Image Similarity API do?

Accepted Answer

The service compares two images and calculates their visual similarity score as a numeric value.

Question 2

How do I interpret the similarity score?

Accepted Answer

The API returns a score ranging from 0 to 1:
* 1.0 — The images are identical.
* 0.9 or higher — The images are very similar.
* Closer to 1 means higher visual similarity; closer to 0 indicates greater differences.

Question 3

How can I provide the images?

Accepted Answer

You can submit images in two ways:
* Via a public direct link (URL).
* As a Base64-encoded string.

Question 4

Which file formats are supported?

Accepted Answer

The API supports JPG, JPEG, PNG, and WEBP.

Question 5

What is the trim_frames parameter used for?

Accepted Answer

The trim_frames parameter automatically removes single-color borders or frames around the edges of images before comparing them. This prevents background margins from skewing the final similarity score.
