# ListRouteCalculators
<a name="API_ListRouteCalculators"></a>

**Important**  
This operation is no longer current and may be deprecated in the future. We recommend you upgrade to the Routes API V2 unless you require Grab data.  
 `ListRouteCalculators` is part of a previous Amazon Location Service Routes API (version 1) which has been superseded by a more intuitive, powerful, and complete API (version 2).
The Routes API version 2 has a simplified interface that can be used without creating or managing route calculator resources.
If you are using an AWS SDK or the AWS CLI, note that the Routes API version 2 is found under `geo-routes` or `geo_routes`, not under `location`.
Since Grab is not yet fully supported in Routes API version 2, we recommend you continue using API version 1 when using Grab.
Start your version 2 API journey with the Routes V2 [API Reference](/location/latest/APIReference/API_Operations_Amazon_Location_Service_Routes_V2.html) or the [Developer Guide](/location/latest/developerguide/routes.html).

Lists route calculator resources in your AWS account.
