  title: Apigee API Hub Discover and Search
  summary: Run a full-text search across API Hub, then read a matching API and list its versions.
  description: >-
    The API Hub discovery flow. The workflow runs a full-text search across all
    API Hub resources, then reads a specific API by id and lists its versions to
    drill into a discovered result. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
