Plan and Agents

After switch to API I’ll use Agents in general.
In the same time I have some older project developed via Plan. Today cannot get result - HTTP in/out nodes doesn’t work.
Is it possible to use Plan after switching to API?

Yes, the planner still functions once you are on the beta - but we would like to encourage users to stay away from the HTTP In/Out nodes. The plan is to eventually remove the planner view.
