## 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 change_1y above a cutoff

```bash
curl -G "https://api.tickerbot.io/v2/signals/change_1y" \
  --data-urlencode "condition=> 3.0711" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

```json
{
 "as_of": "2026-08-18T00:23:07.408Z",
 "signal": "change_1y",
 "condition": "> 3.0711",
 "universe": null,
 "count": 2,
 "results": [
  {
   "ticker": "RVMDW",
   "name": "Revolution Medicines, Inc. Warrant",
   "value": 62.6651
  },
  {
   "ticker": "AXTI",
   "name": "AXT Inc",
   "value": 43.4583
  }
 ]
}
```

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

```bash
curl -G "https://api.tickerbot.io/v2/signals/change_1y" \
  --data-urlencode "condition=> 3.0711" \
  -d "asof=2026-05-20" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

```json
{
 "as_of": "2026-05-20",
 "signal": "change_1y",
 "condition": "> 3.0711",
 "universe": null,
 "count": 2,
 "results": [
  {
   "ticker": "STRC",
   "name": "Strategy Inc Variable Rate Series A Perpetual Stretch Preferred Stock",
   "value": 18532.093198045844
  },
  {
   "ticker": "EMA",
   "name": "Emera Incorporated",
   "value": 8513.11475409836
  }
 ]
}
```

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

```bash
curl -X POST "https://api.tickerbot.io/v2/signals/change_1y/subscribe" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"condition": "> 3.0711", "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=change_1y IS NOT NULL" \
  -d "order=change_1y" -d "columns=change_1y" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

curl -X POST "https://api.tickerbot.io/v2/scan/subscribe" \

  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"q": "change_1y > 3.0711", "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
