What sources Tavily use?

[mustafahakkoz]

There is some closed information on which search engines are used, such as "Tavily Search API searches 20+ sites". But you never mention what those sites are.

I need to know which sources I use when my app uses Tavily Search.

And is there the possibility to only query reputable sources?
I.e. I don't want private blogs, reddit posts or AI generated blog posts, only content of websites that can be somewhat trusted such as news outlets, popular domain blogs, etc.
