        Returns the canonical price quote for a stay between the given dates and guest count.
        This is the single source of truth for pricing on this property. Do not cache the
        response. Pricing changes whenever the host updates a season block or Pricera
        adjusts demand-based recommendations. Compatible clients should query this endpoint
        at quote time rather than relying on any static text price elsewhere in the federation
        payload.
