  title: Google Maps Search for a Place and Assemble a Place Card
  summary: Text search for a place, read its full details, then fetch a photo URI for rendering.
  description: >-
    Everything needed to render a rich place card from a natural-language query.
    A text search narrows to a candidate, Place Details fills in the fields the
    search field mask deliberately left out, and the photo endpoint turns a photo
    resource into a displayable URI. The photo step requests skipHttpRedirect so
    a JSON body with photoUri comes back instead of an opaque image redirect,
    which is what you want when caching or proxying images. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Go from a natural-language query to a detailed place plus a renderable photo URI.
  description: >-
    Searches places by text, confirms a candidate came back, enriches it through
    Place Details, and resolves one of its photos into a short-lived URI.
  inputs:
    type: object
    required:
    - textQuery
    - photoReference
    properties:
      textQuery:
        type: string
        description: The natural-language query to search for (e.g. "pizza in New York").
      photoReference:
        type: string
        description: >-
          The trailing photoReference segment of a photo resource name. Place
          Details returns photo resource names in the form
          places/{placeId}/photos/{photoReference}; this workflow surfaces the
          first one as the photoResourceName output of the readPlaceDetails step,
          and the photo endpoint takes placeId and photoReference as separate
          path parameters. Supply the trailing segment here.
      searchFieldMask:
        type: string
        description: >-
          Comma-separated fields for the text search response. Search field masks
          are prefixed with "places." because results are nested under that key.
        default: places.id,places.displayName,places.formattedAddress,places.location,places.rating,places.photos
      detailsFieldMask:
        type: string
        description: >-
          Comma-separated fields for the Place Details response. Details masks are
          unprefixed because the response is a single Place object.
        default: id,displayName,formattedAddress,location,rating,userRatingCount,photos,websiteUri,regularOpeningHours,editorialSummary
      languageCode:
        type: string
        description: BCP-47 language code for results (e.g. "en").
        default: en
      regionCode:
        type: string
        description: CLDR region code used to bias results (e.g. "US").
        default: US
      maxResultCount:
        type: integer
        description: Maximum number of search results to return (1-20).
        default: 5
      minRating:
        type: number
        description: Only return places rated at least this highly (0.0-5.0).
        default: 0
      maxWidthPx:
        type: integer
        description: Maximum width of the returned photo in pixels (1-4800).
        default: 800

  - stepId: fetchPlacePhoto
    description: >-
      Resolve a photo into a short-lived URI. skipHttpRedirect is set so the
      response is a JSON body carrying photoUri rather than a redirect to image
      bytes, which lets a caller cache or proxy the image itself.
