Read it directly, no script or API key needed; script#research-access says what needs an account. This page lists 20 of 78 reporting institutions; totals use the complete disclosed data.

Sources, coverage & how to read this data
Figures are as reported to the SEC and merged with later amendments where Akkru could match them. Preview limits apply to what is listed, not to the totals, which come from the complete reported data. Nothing is zero-filled: a missing quarter or month is shown as missing.
