Are all cesium API free?

Are all cesium API free? Even for commercial use?

That’s a bit of a broad question, but I think the answer is “no”. You should probably try to be more specific so that I can answer your actual question, but I’ll give you a brief overview of the situation here.

Cesium for Unreal is open source under the Apache 2.0 license:

It’s extremely permissive, allowing the plugin to be used without cost, even in commercial applications. You can use it to connect to any source of 3D Tiles, which is an open standard. However, most sources of 3D Tiles will have their own terms, and may or may not be free for commercial use.

Our own datasets available from our Cesium ion service, such as Cesium World Terrain, are governed by these terms of use:

In general, Cesium ion is only free for non-commercial use.

If you’re using the Google Maps Photorealistic 3D Tiles tileset, that’s covered by separate terms of use. So you need to check the terms of use of the datasets you want to use before using them in your application.

thank you

So everything except Cesium ion is free to use on commercial ?
Is there any information about the API included in Cesium ion that can refer to?

No, I didn’t say “everything except Cesium ion is free to use on commercial.” I hope it goes without saying that the license agreements are the final word here, so you need to read and understand them. My summary has no legal standing.

Cesium ion documentation is here:
