Hotel price tracking with Google Hotels data: an API in 10 minutes (Python + n8n)

Google Hotels already compares every booking site for a hotel and a stay — Booking.com, Expedia, Agoda, Hotels.com and the hotel's own site. It has a "track prices" button too, but it emails you on its own terms, picks the sources, and keeps the history. If you want the numbers — for a trip, a rate parity check, or a price history chart — you need them as rows. This is how to get Google Hotels prices for exact dates as JSON, without a Google API key (there is no public Google Hotels API for reading prices; the official Hotel APIs are feeds for hotels sending prices to Google), and how to turn that into daily hotel price tracking. 1. One request, every booking site's rate The Google Hotels Prices Scraper on Apify takes a place search or a list of hotels, a stay, occupancy and currency, and returns three row types: hotel (lowest nightly rate + stay total), offer (each source's rate, free‑cancellation flag, deep link) and status . You pay per priced row; sold‑out hotels and empty searches are free. curl -X POST "https://api.apify.com/v2/acts/kestrel~google-hotels-prices/run-sync-get-dataset-items?token= $APIFY_TOKEN " \ -H "Content-Type: application/json" \ -d '{"queries": ["hotels in Lisbon"], "checkIn": "2026-10-03", "checkOut": "2026-10-06", "adults": 2, "currency": "USD", "maxHotels": 20}' A hotel row looks like this: { "type" : "hotel" , "name" : "The Central House Lisbon Baixa" , "check_in" : "2026-10-03" , "check_out" : "2026-10-06" , "nights" : 3 , "nightly" : 81.81 , "nightly_display" : "$82" , "total" : 245 , "stars" : 2 , "rating" : 4.3 , "reviews" : 727 , "deal" : "19% less than usual" , "entity_id" : "ChkIg-b2ismUj7M1Gg0vZy8xMWg3MThreGg1EAE" , "google_url" : "https://www.google.com/travel/hotels/entity/ChkI…" } and an offer row (with "includeOffers": true ): { "type" : "offer" , "name" : "Hyatt Regency Lisbon" , "source" : "Booking.com" , "official" : false , "nightly" : 569.35 , "total" : 1708.05 , "free_cancel" : true , "free_cancel_until" : "Oct 1" , "p
