 In most situations, all you need to do is to specify the types for your API using the GraphQL schema language, taken as an argument to the `buildSchema` function.
 
 The GraphQL schema language supports the scalar types of `String`, `Int`, `Float`, `Boolean`, and `ID`, so you can use these directly in the schema you pass to `buildSchema`.

 Each of these types maps straightforwardly to JavaScript, so you can just return plain old JavaScript objects in APIs that return these types. Here's an example that shows how to use some of these basic types:

 Just like a REST API, it's common to pass arguments to an endpoint in a GraphQL API. By defining the arguments in the schema language, typechecking happens automatically. Each argument must be named and have a type. For example, in the [Basic Types documentation](/basic-types/) we had an endpoint called `rollThreeDice`:

 Instead of hard coding “three”, we might want a more general function that rolls `numDice` dice, each of which have `numSides` sides. We can add arguments to the GraphQL schema language like this:

 The exclamation point in `Int!` indicates that `numDice` can't be null, which means we can skip a bit of validation logic to make our server code simpler. We can let `numSides` be null and assume that by default a die has 6 sides.

 When you call this API, you have to pass each argument by name. So for the server above, you could issue this GraphQL query to roll three six-sided dice:

 Let's modify our “hello world” example so that it's an API server rather than a script that runs a single query. We can use the 'express' module to run a webserver, and instead of executing a query directly with the `graphql` function, we can use the `graphql-http` library to mount a GraphQL API server on the “/graphql” HTTP endpoint:
