Booking.com Price Fetch Integration

We are a travel agency selling hotel rooms. Before we quote a price to a customer on our website, we want to see what the same hotel costs on Booking.com, compare it with our own supplier rate, and set our price accordingly. What we need: Connect to the Booking.com Demand API For a given hotel + check-in/check-out date + number of guests, pull the current Booking.com price Return it to our system so we can compare it with our own rate before quoting Basic caching so we don't call the API more than necessary Handle errors and rate limits cleanly That's the core of the job. We don't need booking creation for now — just prices. Our stack: Cloudflare Workers, D1, JavaScript/TypeScript. Simple setup, no heavy build tools.
