## 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 news_volume above a cutoff

```bash
curl -G "https://api.tickerbot.io/v2/signals/news_volume" \
  --data-urlencode "condition=> 2.5" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

```json
{
 "as_of": "2026-08-18T00:24:53.090Z",
 "signal": "news_volume",
 "condition": "> 2.5",
 "universe": null,
 "count": 2,
 "results": [
  {
   "ticker": "DHR",
   "name": "Danaher Corporation",
   "value": 10
  },
  {
   "ticker": "LHX",
   "name": "L3Harris Technologies, Inc.",
   "value": 6.5
  }
 ]
}
```

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

```bash
curl -X POST "https://api.tickerbot.io/v2/signals/news_volume/subscribe" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"condition": "> 2.5", "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=news_volume IS NOT NULL" \
  -d "order=news_volume" -d "columns=news_volume" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

```json
{
 "as_of": "2026-08-18T00:24:53.338Z",
 "query": {
  "q": "news_volume IS NOT NULL",
  "limit": 2,
  "order": "news_volume",
  "dir": "desc",
  "fields": [
   "news_volume"
  ],

   "ticker": "DHR",
   "name": "Danaher Corporation",

   "relative_volume": null,
   "market_cap": 142319526632,

  {
   "ticker": "LHX",

   "asset_class": "stocks",
   "asset_type": "CS",
   "price": 280.349,

   "relative_volume": null,
   "market_cap": 54341149241,
   "news_volume": 6.5
  }
 ]
}
```

#### 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": "news_volume > 2.5", "target_url": "https://example.com/hooks/tickerbot"}'
```

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