  title: Exa Answer with Deep Sources
  summary: Get a cited answer to a question, then deep-fetch the top citation.
  description: >-
    Turns the Exa answer endpoint into a grounded research step. The workflow
    asks a natural-language question and receives a direct answer along with the
    citations Exa used to ground it, then takes the top citation and retrieves
    its full extracted text and a summary from the contents endpoint so the
    caller can verify the answer against the complete source document. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
