Are there more endpoints available then what is in the API overview?
The vast majority of what API users need is available through the Query API call and Entity API call. The Entity API call allows you to Create/Read/Update/Delete any entity defined in the system. The Query API call allows you to search for lists of entities in the system using a powerful filtering syntax. If you are trying to do things beyond this, other API calls may be available to suit your needs. We can work with you to determine other specialized API calls you may need to call and how to call them.
