"# Function calling for nearby places: Leveraging the Google Places API and customer profiles\n",
"\n",
"This notebook is centered around the integration of the Google Places API and custom user profiles to enhance location-based searches. Our approach involves using the Google Places API in combination with user preferences, aiming to make location discovery more personal and relevant. Please note that while we focus on the Google Places API in this instance, there are numerous other APIs you could explore and apply in a similar fashion.\n",
"\n",
"We'll explore the application of three main components:\n",
"\n",
"- Customer profile: This mock profile captures individual preferences for types of places (e.g., restaurants, parks, museums), budget, preferred ratings, and other specific requirements. \n",
"\n",
"- Google Places API: This API provides real-time data about nearby places. It factors in various data points such as ratings, types of venues, costs, and more from the locations around you.\n",
"\n",
"- Function calling: A single command such as \"I'm hungry\" or \"I want to visit a museum\" activates the function which combines the user profile data and Google Places API to identify suitable venues.\n",
"\n",
"This notebook introduces two primary use cases:\n",
"\n",
"- Profile-based recommendations: Learn how to create a user profile and make place recommendations based on individual preferences.\n",
"\n",
"- API integration with function calling: Understand how to integrate and call Google Places API effectively to source real-time data of various places using function calling.\n",
"\n",
"Please note that while this system is highly versatile, its effectiveness may vary based on user preferences and available place data. For the purposes of this notebook, the customer data is fake and the location is hardcoded. "

"Google Places API\n",
"\n",
"To use the Google Places API, you'll need two things:\n",
"\n",
"- Google Account: If you don't already have one, you will need to create a Google account.\n",
"\n",
"- Google Places API Key: The API key is a unique identifier that is used to authenticate requests associated with your project for usage and billing purposes. You can get your API key from the [Google Cloud Console](https://console.cloud.google.com/getting-started?authuser=1). \n",
"\n",
"\n",
"\n",
"Please note that Google Places API is a paid service, and the cost is associated with the number of API calls made. Keep track of your usage to avoid any unexpected charges.\n",
"\n",
"\n",
"\n",
"The requests library is also needed, you can download it by using the following command: \n",

However, remember to navigate the fine line of interpretation and assumption: if a user's intent is unclear or can be interpreted in multiple ways, do not hesitate to politely ask for additional clarification.
