  description: >-
    The Dagster GraphQL API allows clients to interact with Dagster programmatically. It can be used to query
    information about Dagster runs, retrieve metadata about repositories, jobs, and ops, and launch runs. The GraphQL
    endpoint is served by the webserver at the /graphql route.

  description: >-
    The Dagster External Assets REST API provides endpoints to report asset materializations, asset check evaluations,
    and asset observations for external assets back to Dagster. This allows you to notify Dagster that an external
    asset has been updated and include metadata about the event.
