# API

It is also possible to access the GraphML information via a Pentaho Server API. There are REST endpoints available to retrieve the lineage related artifacts.

Below are some example `curl` commands which exercise the REST endpoints available on the Pentaho Server. These calls use basic authentication. For more information on the various ways to authenticate with the Pentaho Server, see **Authenticate with the server before making service calls** in the Pentaho REST API documentation.

For more detailed information about the REST endpoints available, you can go to the Pentaho Wiki to view the [attached Enunciate file](https://help.pentaho.com/@api/deki/files/20549/metaverse-enunciate.zip?revision=1).
