Topic: [Feature] API Upload Duplicate Response

Requested feature overview description.
When uploading stuff over API that already exist, we should get information about the post ID.

Why would it be useful?
Well for one, it would work like website then and since server already checked and confirmed it exists, it could pass that information instead of just saying "It exists".
Then we wouldn't need to either search similar images, or try to upload via website to find the post(ID).
We could just jump straight to ID and do whatever with it.

What part(s) of the site page(s) are affected?
API
