# get_short_activity

> Get short activity

**Get short activity** · \$0.02 per call (x402, USDC)

Retrieves retained short-interest and short-volume history for one ticker. Select family and date bounds; short\_interest uses settlement periods, while short\_volume uses observation dates. Returns typed outstanding short shares, average daily volume and days to cover, or daily short/exempt/total volumes, with exact source support. Short volume does not establish an outstanding position. Current requests recheck stale mirror metadata; historical and pinned reads never refresh. Continue with the returned snapshot, as\_of, filters and cursor or next\_offset; coverage gaps remain explicit.
