How to grep multiple html pages on a domain?

I essentially want to Ctrl-F multiple sites in a browser.

I have a range of URLs on a domain https://exampleblog.com/posts/{1-50}

I want to grep all of the pages under /posts/ at once. They are each identified with an ordered int from 1 to 50. Is there a way to do this without downloading with wget? I want to grep the information I get back from curl. I feel like there is an eloquent pipeline or one liner that would allow me to do this from the terminal without downloading (although it may be slow).
