# 🧱 Build a Dynamic Travel Planner Using Replit and Dappier Real-Time Data Model

## **Introduction**

In this step-by-step guide, we will walk you through building a **Dynamic Travel Planner** using **Replit** and **Dappier's Real-Time Data Model API**. This app will generate a **customized travel itinerary** based on the **user's chosen destination** and **number of days**, providing **real-time weather updates, hotel deals, and local attractions**. By leveraging **OpenAI's LLMs** and **Dappier’s enriched real-time data**, users can generate **AI-powered travel plans** within minutes.

## **Dappier Real-Time Data Model API**

The **Dappier Real-Time Data Model API** enables applications to retrieve **verified and up-to-date** information from trusted sources across multiple domains, including **weather, finance, and news**. It allows seamless integration of real-time data into AI-powered applications.

### **Usage in Python**

The API can be used to fetch real-time data with a simple function call:

```python theme={null}
response = app.search_real_time_data(
   query="What is the stock price of Apple?",
   ai_model_id="am_01j06ytn18ejftedz6dyhz2b15"
)
```

### **Parameters**

* **query (str)**: The user-provided search query. Example queries include:

  * `"How is the weather today in Austin, TX?"`
  * `"What is the latest news for Meta?"`
  * `"What is the stock price for AAPL?"`

* **ai\_model\_id (str)**: The AI model ID to use for the query.
  * AI model IDs always start with the prefix `"am_"`.
  * Multiple AI model IDs are available at the **Dappier Marketplace**.

In our **Dynamic Travel Planner**, we will use this API to fetch **weather updates and hotel deals** dynamically.

## **Step 4: Generate the Travel Planner Using Replit’s AI Assistant**

Instead of writing the code manually, **Replit’s AI Assistant** can generate the entire app for you by following these simple instructions:

1. Open the **Assistants App** in Replit.
2. Enter the following instructions:
   > **"Create a travel planner app that asks the user for their destination city and the number of days for the trip. Fetch real-time weather updates and hotel deals for the given destination using Dappier's Real-Time Data API. Use OpenAI to generate a structured, well-balanced itinerary that includes local attractions, sightseeing options, and relaxation spots. The app should be interactive and provide users with dynamic travel recommendations."**
3. Replit’s AI will automatically generate the code for your app.
4. Accept the code suggestions and let Replit set up everything for you.
5. Run the app to verify it works as expected.

By using **Replit’s AI Assistant**, you can build your **Dynamic Travel Planner** **without writing a single line of code manually**.
