  Generated by API Evangelist from the documented FusionFeed GraphQL
  subscription transport. FusionFeed pushes live data (e.g. telemetry, stats,
  scoreboard updates) to clients via GraphQL subscriptions over WebSocket using
  the graphql-ws protocol at /v2/graphql-ws. This AsyncAPI captures that real
  streaming surface; the concrete subscription fields are defined in the
  provider's GraphQL schema, not published as a standalone document.

  title: FusionFeed Realtime (GraphQL Subscriptions)
  version: v2
  description: >-
    Live push of sports data from FusionFeed over WebSocket. Subscriptions use
    the graphql-ws protocol (legacy subscriptions-transport-ws is also
    supported). Authentication is provided in the connection-init parameters as
    {"authorization": "token MY_API_KEY"} because browsers cannot set WebSocket
    headers.
