  title: fal Serverless App Discovery
  summary: List deployed Serverless apps, then fetch full metadata and scaling for the first one.
  description: >-
    A control-plane introspection pattern for fal Serverless. The workflow
    lists every Serverless app deployed under the calling key's organization,
    selects the first returned app, and retrieves its full metadata including
    endpoint URL and current scaling parameters. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
