Zesty.io provides endpoints to power a GraphQL server for any instance, you can follow a full tutorial to launch an Apollo GQL server by using this code base on Github https://github.com/zesty-io/graphql-zesty
For any Zesty.io Content Instance you may turn on the GQL setting in the content manager > settings > developer. The settings are named [developer][gql] and [developer][gql_origin], if these setting are missing from your instance, reach out to the support slack to have them added.
When GQL is turned on, endpoints will become available at the instance domain like
https://www.acme.com/-/gql/ which is a map file that shows all the endpoints needed.
