KlickerUZH GraphQL API

KlickerUZH is the university's open-source audience-response and interactive-learning platform, developed and hosted by the UZH Department of Banking and Finance. Its backend is a single Apollo GraphQL endpoint. The endpoint is live and validating — an unknown field returns a GRAPHQL_VALIDATION_FAILED error rather than a transport failure — but schema introspection is disabled in production, so no machine-readable schema could be retrieved and none is published on the documentation site. No SDL, no OpenAPI, no public playground.

x-liveness: GET returns 400; POST with a GraphQL document returns a GRAPHQL_VALIDATION_FAILED error from
  Apollo Server, which is a live, schema-validating endpoint. Introspection is disabled in production,
  so the schema itself is not retrievable.
