> You are building a software that uses an AGPL software by calling its APIs : Your software is a covered work and you need to license it under AGPL and make the source code available to your users. A concrete example would be a monitoring software that calls OpenObserve APIs to provide its core functionality.

So, if you use it for logging and send logs to OpenObserve using the OpenObserve API, you need to license your software under AGPL.
