How to enable API access for a project?

EDIT: I think I figured this out. Turns out I'm not using Zoho Projects, I'm using Zoho Bugtracker. Under https://projects.zoho.com I only have a single project. Is there a bugtracker specific API? I have 4 projects when I visit https://bugtracker.zoho.com. 

Hello! I'm just getting started with the Zoho Projects API.

I have gotten an authtoken and have successfully used the get portals and get projects endpoints.

However, my get projects endpoint only returns a single project (even though I have 4 total created). I can request details for the returned project just fine.

However, when I pull the ID for a different project from my URL bar and try to directly access that project, I get: 

{
  "error": {
    "code": 6403,
    "message": "License does not allow further operations"
  }
}

I only need API access on one project, but I do not know how to change which project I can have API access to. How do I do this?
