Not sure which URL to use?

Check the URL shared by our Team or your Organization administrator:

https://api.ig1.ai → You're on the standard IG1 AI API. You're in the right place.
https://api.XXX.ig1.ai or a custom domain → You're using a Private Gateway

A Private Gateway is a dedicated instance with its own access controls, API keys, and model configuration.
