  title: Wolfram|Alpha Query Recognizer Routing
  summary: Classify a query with the Fast Query Recognizer, then route accepted queries to Full Results.
  description: >-
    The Fast Query Recognizer classifies a natural language query in under ten
    milliseconds, reporting whether Wolfram|Alpha is likely to return a useful
    response, the detected domain, and a result significance score. This
    workflow uses that classification as a routing gate: it first recognizes the
    query, and only when the query is accepted does it spend the heavier call to
    the Full Results API for the complete computed pods. When the query is not
    accepted, the flow ends without invoking the expensive backend. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI descriptions.

  summary: Recognize a query and route accepted queries to the Full Results API.
  description: >-
    Submits the query to the Fast Query Recognizer. When the classification is
    accepted, the flow branches to the Full Results API for the complete pod
    data; when it is not accepted, the flow ends after recognition.
