Hey @rbvandyke
The plan type wouldn’t restrict or stop the ability to make requests in any Workspace.
The free version does have limits but these are on the shared history and shared requests. Once you get close to and reach these limits you will be informed by several UI based prompts. The collections will be archived after a period of time if the limits are still breached.
There could be a number of different reasons for that particular request to fail but I don’t believe it would have anything to do with the plan you may have been on.
