Is one visit and one api call is same

I am planning to buy a hosting service for my app api. For one of the plan they said that 10000 visits monthly. What does visit mean. Is it consider one api request as one visit? For eg if a person register in my app and after that he login to app. Here it uses 2 api request. One for login and one for register. Is it consider as 2 visits? Please explain.
