API using image as input

I’ve been struggling a lot to use external API, but I don’t know how to resolve my issue.

I’m trying to implement this website (https://ugatit-gpu.kmswlee.endpoint.ainize.ai/) with Bubble.
The website says it uses an API shared here (Ainize | Launchpad for open-source AI projects)

I tried to connect the API as below, but it seems I didn’t configure it properly.
Could anybody help me out with this? Thanks in advance !!
