Runs an introspection query against a GraphQL server and outputs the servers schema

Usage: cynic introspect [OPTIONS] <URL>

Arguments:
  <URL>
          The URL of the GraphQL schema that we should introspect

Options:
  -H, --header <HEADERS>
          Any headers to send with the introspection request
          
          These should be in HTTP format e.g. `-H "Authorization: Bearer a_token_123"`

  -o, --output <OUTPUT>
          The name of a file we should output the schema into.
          
          By default we print to stdout.

      --server-version <SERVER_VERSION>
          The version of the GraphQL specificaiton that the remote GraphQL server implements
          
          Different versions of GraphQL expose different fields via introspection, so we need to know which set of fields to ask for.
          
          By default we run an additional query to figure out what the server we're talking to supports.
          
          [default: auto]

          Possible values:
          - 2018: Run an introspection query compatible with the 2018 GraphQL specification
          - 2021: Run an introspection query compatible with the 2021 GraphQL specification
          - auto: Run an additional query to determine what the GraphQL server supports
