Does the continuation token has any expiring condition?

When using API the continuation token that gets generated does it have any validity or any expiring condition or is it encoded enough to reproduce same results?

Looking at the code for the Tags APIs it appears the continuation token is basically just a pointer to the last entry in the previous page, and is just used to get the next page of results. As a result it will never expire. Without looking at the queries every API in the system uses I can’t be 100% sure but I believe they all follow the same pattern.
