About the ambientCG API
I hope the assets and information are helpful to you.
There is just one more thing I would like to tell you: In recent years the companies contacting me regarding this website have gotten bigger and bigger. This is not a problem in itself but I would like to make it clear that all of this is operated and and filled with content by just me (Lennart Demes) - a single computer science student. It was built with hobbyists and educators in mind.
If I ever have to go to the hospital for a couple of weeks and something breaks then the API or website will stay broken for those weeks.
It is absolutely fine for even large companies to use the assets or the API. I just want everyone who is using ambientCG commercially to keep this in mind. If you want to be safe: Create your own local copy of the ambientCG library by signing up for a Nextcloud account on Patreon.
