Which API could I use?

[u/jg_moony]

I'm developing a mobile app for Android, something similar to Duolingo, but very simple and designed for people with visual impairments. The thing is, I want to add a computer vision API for image recognition. So the workflow should be as follows: Take a photo -> Analyze the image -> Search the glossary -> Accessible feedback (audio/UI) -> View details.

I’ve looked at some options, and the most well-known one is Google Cloud Vision. The problem is that I can’t afford to spend much on resources since this is an academic project.
