# Front page

`GET /v1/latest`

What bullpen.news shows on its front page now, or on a past day: stories and videos, X posts, and investor letters, each list in the page's order. sector narrows the stories and X posts by their topic tags; it doesn't narrow letters. mincap and maxcap narrow all three by the market cap of the companies they're about. Any other parameter is refused.
