Hello @saschaseniuk ,

Thanks for the PR. Here are a few comments:
1. Please add a Google Colab link at the start. You can refer to this notebook for guidance.
2. Please add more details about the use case at the beginning to help users better understand it.
3. Could you move the setup instructions to the top? This will help users understand how to obtain Mistral and Serper API keys.
5. Please use the latest Mistral client. ChatMessage and MistralClient have been updated in the latest version.
6. I believe this use case can be solved using the StructuredOutput mechanism instead of the function-calling approach. Please check the docs and see if you’d prefer to update the implementation.
7. Run the cookbook and show the outputs of each cell so that users can get a better sense of how things are working.
