## 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 where it fires now

```bash
curl "https://api.tickerbot.io/v2/signals/below_premarket_low" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

```json
{
 "as_of": "2026-08-18T00:22:54.262Z",
 "signal": "below_premarket_low",
 "condition": null,
 "universe": null,
 "count": 2,
 "results": [
  {
   "ticker": "AACPR",
   "name": "Apogee Acquisition Corp Rights",
   "value": true
  },
  {
   "ticker": "ANNAW",
   "name": "AleAnna, Inc. Warrant",
   "value": true
  }
 ]
}
```

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

```bash
curl -X POST "https://api.tickerbot.io/v2/signals/below_premarket_low/subscribe" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"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, filtered on this signal

```bash
curl -G "https://api.tickerbot.io/v2/scan" \
  --data-urlencode "q=below_premarket_low" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

```json
{
 "as_of": "2026-08-18T00:22:54.676Z",
 "query": {
  "q": "below_premarket_low",
  "limit": 2,
  "order": "day_change_pct",
  "dir": "desc",
  "fields": [],
  "full": false,
  "universe": null,
  "asset_class": null
 },
 "count": 2,
 "results": [
  {
   "ticker": "MNDO",
   "name": "Mind CTI Ltd",
   "asset_class": "stocks",
   "asset_type": "CS",
   "price": 1.035,
   "day_change_pct": 0.0147,
   "gap_pct": -0.0196,
   "relative_volume": null,
   "market_cap": 20588869
  },
  {
   "ticker": "WENNU",
   "name": "Wen Acquisition Corp Unit",
   "asset_class": "stocks",
   "asset_type": "UNIT",
   "price": 10.49,
   "day_change_pct": 0.0029,
   "gap_pct": 0.0036,
   "relative_volume": 12.0554,
   "market_cap": null
  }
 ]
}
```

#### 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": "below_premarket_low", "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 events — `/v2/events`

The flag as a timeline: each edge as a point event, and the spans it stayed true. (https://tickerbot.io/docs/endpoints/events.md)

#### Firings — every enter edge as a point event

```bash
curl -G "https://api.tickerbot.io/v2/events" \
  -d "kind=signal" -d "signal=below_premarket_low" -d "transition=enter" -d "since=2026-01-10" \
  -H "Authorization: Bearer YOUR_KEY"
```

}
```

#### Spans — when it was true for one ticker (ZUMZ)

```bash
curl "https://api.tickerbot.io/v2/signals/below_premarket_low/ZUMZ/events" \
  -H "Authorization: Bearer YOUR_KEY"
```
