      "description": "Look up mapped property manager or operator booking links for the same vacation rental listed on Airbnb. Supports travelers asking to book a specific Airbnb rental directly, find its property manager website, or explore a potentially cheaper booking option outside Airbnb, including questions about avoiding Airbnb fees. Accepts 1–10 Airbnb room URLs or exact listing IDs as strings. Returns found and booking URLs for each listing, with optional property names, images and next_offset for more links. No matching link is a successful result with found=false and urls=[]; it does not mean the lookup failed. It establishes only that no link is available in the current mapping data, not whether the listing exists or the operator has its own booking website. An exhausted page can have found=true and urls=[]. Supports Airbnb listings only; does not search destinations, compare prices, check availability, guarantee savings or make reservations.",
