# GetInstanceTypesFromInstanceRequirements
<a name="API_GetInstanceTypesFromInstanceRequirements"></a>

Returns a list of instance types with the specified instance attributes. You can use the response to preview the instance types without launching instances. Note that the response does not consider capacity.

When you specify multiple parameters, you get instance types that satisfy all of the specified parameters. If you specify multiple values for a parameter, you get instance types that satisfy any of the specified values.
