Type-safe booking for Pydantic AI

Every response from `book_hotel` is validated against your Pydantic models. If the API returns a malformed structure, your agent catches it immediately. This prevents runtime errors during the booking flow. You define the expected output, and Pydantic AI enforces it during the interaction with the Expedia server.

Strict rate validation in Pydantic AI

Use `check_availability` to get the latest room data. Because Pydantic AI validates the schema, your agent knows exactly which rate plans are available before it proceeds. Run `price_check` to verify the final quote. The agent fails if the price has changed, ensuring you never book a room at an incorrect rate.

Reliable data retrieval for Pydantic AI

Fetch property details with `get_hotel_details` and trust the outcome. Pydantic AI maps the response to your models, making it easy to access amenities or policies. Use `get_guest_reviews` to pull feedback data. The strict typing ensures your agent only processes valid review objects, keeping your logic clean and predictable.
