Short data is one of ~60 endpoints.
The same key unlocks SEC filings, financials, insider trades, 13F holdings, fails-to-deliver and more — every record resolved to one canonical entity, in one JSON shape.
Short-sale volume is published by FINRA under Regulation SHO and is in the public domain. Clous is independent of, and not affiliated with, FINRA. Data is context for research, not investment advice.
