One ticker's insider (Form 4) activity

GEThttps://api.skylit.ai/v1/underlying/{ticker}/insider

SEC Form 4 lines for {ticker} in the window, newest transaction first, with an open-market summary and a monthly series. The summary and monthly cover the whole window whatever limit, offset and action are; only open-market buys and sells (codes P and S) count toward them, since grants, exercises and tax withholding are compensation rather than a view. Windows are on the TRANSACTION date; defaults to the last 365 days, up to 3660 days (data starts 2003). Share classes accept BRK.B, BRK-B or BRKB.
