  title: ChatGPT Web Search Grounded Answer
  summary: Answer a question with the built-in web search tool and return citations.
  description: >-
    Uses the Responses API built-in web_search_preview tool to answer a
    current-events question. The response is created with the tool enabled,
    then retrieved to extract both the generated answer text and the URL
    citations the model attached as annotations. The flow branches when the
    response did not complete so callers can react to a failed or incomplete
    run. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
