I believe only very few users have access to a Notion API key and would be willing to enter it in this tutorial with write access to their Notion. Running the tutorial also worked for me when just entering "key" in the getpass input field. I suggest we mention in the beginning of the tutorial that users can also run it without a Notion API key by leaving it empty if that works too. Have you tried Duckduckgo? Did you run into rate limits? If not, we could think about making it the default or at least automatically switching to it if the user doesn't enter a SerperDev key

By the way, there is a prompt Save the this text on Notion: that we should update.

@julian-risch, I made the DuckDuckGo search component the default one and suggested using SerperDevWebSearch if users hit the rate limit. And yes, I hit the rate limit a couple of times, but for users, it won't happen (hopefully) if they don't run the notebook more than once or twice.

Regarding notion, no, it doesn't work without the proper API key; it just doesn't throw an error, as the Notion API doesn't make this check until we send a request to create a page. It just returns a response with success:False

You have a point about providing the notion access, but users need to give the page ID and limit the page to which this component has access. Either way, users are free not to use the notion tool in their agent, but this tutorial provides nice guidance for those who want to. That's why I marked this tutorial as "advanced"
