## 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/at_session_low" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

```json
{
 "as_of": "2026-08-18T00:22:48.479Z",
 "signal": "at_session_low",
 "condition": null,
 "universe": null,
 "count": 2,
 "results": [
  {
   "ticker": "AAA",
   "name": "Alternative Access First Priority CLO Bond ETF",
   "value": true
  },
  {
   "ticker": "AAAA",
   "name": "Amplius Aggressive Asset Allocation ETF",
   "value": true
  }
 ]
}
```

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

```bash
curl "https://api.tickerbot.io/v2/signals/at_session_low?asof=2026-05-20" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

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

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

```bash
curl -X POST "https://api.tickerbot.io/v2/signals/at_session_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=at_session_low" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

  }
 ]
}
```

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

```bash
curl -G "https://api.tickerbot.io/v2/scan" \
  --data-urlencode "q=at_session_low" \
  -d "asof=2026-05-20" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

```json
{
 "as_of": "2026-05-20",
 "query": {
  "q": "at_session_low",

  "dir": "desc",
  "fields": [],
  "full": false,
  "universe": 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": "at_session_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 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,at_session_low" \
  -H "Authorization: Bearer YOUR_KEY"
```

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

 "tickers": [
  "AAPL",
  "MSFT"
 ],

  "close",
  "at_session_low"

  "AAPL": [
   {

   },
   {
    "t": "2026-08-13",
    "close": 305.26,
    "at_session_low": false
   },
   {
    "t": "2026-08-14",

    "close": 495.4,
    "at_session_low": false
   }
  ]
 }
}
```

### 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=at_session_low" -d "transition=enter" -d "since=2026-01-10" \

```bash
curl "https://api.tickerbot.io/v2/signals/at_session_low/ZTWO/events" \
