# short_interest

Raw shares-shorted count as last reported (FINRA bi-monthly). Pair with `short_interest_settlement_date` (profile.ts) for the as-of date.

A bigint signal column on the Tickerbot computed state table (20,798+ ticker rows) — computed by the platform, queryable by bare name across the API. Values are NULL on rows the signal doesn't apply to.

- Group: Fundamentals
- Category: Short interest
- Type: bigint
- Unit: shares
- Update cadence: post-close daily
- Intervals: 1d
- Universe: all tickers
- History: recent only (forward-only from first computation)
- Nullable: yes

## Query it

Every applicable form factor, grouped by endpoint family. Response payloads are real captures, sampled 2026-08-18 and trimmed; your run's values and dates will differ.

### Use signals — `/v2/signals/{signal}`

One signal across the market: who matches now, who matched then, and a push when someone starts. (https://tickerbot.io/docs/endpoints/signals.md)

#### Live — every ticker with short_interest above a cutoff

```bash
curl -G "https://api.tickerbot.io/v2/signals/short_interest" \
  --data-urlencode "condition=> 63394520" \
  -H "Authorization: Bearer YOUR_KEY"
```

Response (sampled 2026-08-18, trimmed):

```json
{
 "as_of": "2026-08-18T00:25:47.885Z",
 "signal": "short_interest",
 "condition": "> 63394520",
 "universe": null,
 "count": 2,
 "results": [
  {
   "ticker": "PLUG",
   "name": "Plug Power Inc.",
   "value": 294021600
  },
  {
   "ticker": "NVDA",
   "name": "Nvidia Corp",
   "value": 292667375
  }
 ]
}
```

#### As-of — the same read at a past date

```bash
curl -G "https://api.tickerbot.io/v2/signals/short_interest" \
  --data-urlencode "condition=> 63394520" \
  -d "asof=2026-05-20" \
  -H "Authorization: Bearer YOUR_KEY"
```

Response (sampled 2026-08-18, trimmed):

```json
{
 "as_of": "2026-05-20",
 "signal": "short_interest",
 "condition": "> 63394520",
 "universe": null,
 "count": 0,
 "results": []
}
```

#### Subscribe — webhook when a ticker starts matching

```bash
curl -X POST "https://api.tickerbot.io/v2/signals/short_interest/subscribe" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"condition": "> 63394520", "target_url": "https://example.com/hooks/tickerbot"}'
```

Returns 201 with the created webhook — the same shape as GET /v2/webhooks/{id}, plus a one-time signing_secret for HMAC verification.

### Use scan — `/v2/scan`

The whole market through a WHERE clause — this signal composed freely with any other column. (https://tickerbot.io/docs/endpoints/scan.md)

#### Live — the whole market, ranked by this column

```bash
curl -G "https://api.tickerbot.io/v2/scan" \
  --data-urlencode "q=short_interest IS NOT NULL" \
  -d "order=short_interest" -d "columns=short_interest" \
  -H "Authorization: Bearer YOUR_KEY"
```

Response (sampled 2026-08-18, trimmed):

```json
{
 "as_of": "2026-08-18T00:25:51.144Z",
 "query": {

   "market_cap": 5453600360000,
   "short_interest": 292667375
  }
 ]
}
```

#### As-of — the same scan at a past date

```bash
curl -G "https://api.tickerbot.io/v2/scan" \
  --data-urlencode "q=short_interest IS NOT NULL" \
  -d "order=short_interest" -d "columns=short_interest" \
  -d "asof=2026-05-20" \
  -H "Authorization: Bearer YOUR_KEY"
```

Response (sampled 2026-08-18, trimmed):

```json
{
 "as_of": "2026-05-20",
 "query": {
  "q": "short_interest IS NOT NULL",
  "asof": "2026-05-20",
  "interval": "auto",
  "limit": 2,
  "order": "short_interest",
  "dir": "desc",
  "fields": [
   "short_interest"
  ],
  "full": false,
  "universe": null,
  "asset_class": null
 },
 "count": 0,
 "results": []
}
```

#### Subscribe — webhook on a market-wide condition

```bash
curl -X POST "https://api.tickerbot.io/v2/scan/subscribe" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"q": "short_interest > 63394520", "target_url": "https://example.com/hooks/tickerbot"}'
```

Returns 201 with the created webhook object; deliveries carry the tickers matching the condition at each evaluation.

### Use series — `/v2/series`

Its history over time, on one aligned grid. (https://tickerbot.io/docs/endpoints/series.md)

#### History — the column on an aligned time grid

```bash
curl "https://api.tickerbot.io/v2/series?tickers=AAPL,MSFT&columns=close,short_interest" \
  -H "Authorization: Bearer YOUR_KEY"
```

Response (sampled 2026-08-18, trimmed):
