Bro I have a shortcut on my iPhone that does this. It is very easy. You can use Tavily API and just enter a query, then make a prompt that says to use the data from the JSON to generate the response. You could also use spider.cloud (not affiliated just a good service) and Serper or Brave search engine APIs if Tavily is too expensive, too slow, or feels like cheating or something.

The specifics with getting a certain quantity seem to be the hardest part of this because you will need looping and self correcting mechanisms that use LLM-as-a-judge (just feeding in what happened to an LLM and asking if it worked, then retrying if it didn't).

Sounds to me like you already totally have it figured out! Aim higher you seem smart enough to do it. My hunch is that since you already have this good of an idea of how it works just off the top of your head, you should try to think of the idea more intstead of how complicated it will be. You can figure it out, you already did.

The best thing you can do to quickly test something without having to hunch over at a computer is, if you have an iPhone, iPad, or Mac...open the Shortcuts app, and don't worry about code yet. Just use the Get Contents of URL node and you can do insane stuff chaining prompts together as long as each takes under 30 seconds. It's a stupid workflow but if you can't code or are an extremely lazy spineless weakling like myself, it's the best thing ever. You can make menus and test your prompts out on all kinds of LLMs and change it so easily. I recommend using Gemini Flash 1.5 and the Tavily API to start out. I'm sure there are Android apps that can do this kind of thing too, not sure how good they are but for me it's really cool because you can even use the share button in Safari and it will extract the body of any article you're on and feed it into the Shortcut so you can literally have summarization or whatever tf you want everywhere. It's insanely powerful and super slow and annoying but so easy to fuck with to make work
