Query it

Every applicable form factor, grouped by endpoint family. Swap YOUR_KEY for the value from /dashboard/keys. 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. Docs →

Live — every ticker where it fires now
curl "https://api.tickerbot.io/v2/signals/at_session_low" \
  -H "Authorization: Bearer YOUR_KEY"
Response (sampled 2026-08-18, trimmed)

Subscribe — webhook when a ticker starts matching
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. Docs →

Live — the whole market, filtered on this signal

Subscribe — webhook on a market-wide condition
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. Docs →

History — the column on an aligned time grid
curl "https://api.tickerbot.io/v2/series?tickers=AAPL,MSFT&columns=close,at_session_low" \

    "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. Docs →

Firings — every enter edge as a point event
curl -G "https://api.tickerbot.io/v2/events" \
  -d "kind=signal" -d "signal=at_session_low" -d "transition=enter" -d "since=2026-01-10" \

  {
   "ticker": "ZTR",

    "transition": "enter",
    "price": 6.755,
    "definition_version": 6
   }
  }
 ]
}
Spans — when it was true for one ticker (ZTWO)
curl "https://api.tickerbot.io/v2/signals/at_session_low/ZTWO/events" \
  -H "Authorization: Bearer YOUR_KEY"
Response (sampled 2026-08-18, trimmed)
{
 "as_of": "2026-08-18T00:22:54.223Z",
 "ticker": "ZTWO",
 "signal": "at_session_low",
 "count": 2,
 "events": [
  {
   "started_at": "2026-08-14T20:00:00.000Z",
   "ended_at": "2026-08-15T20:00:00.000Z",
   "start_price": 50.4,
   "end_price": 50.4,
   "definition_version": 6
  },
  {
   "started_at": "2026-08-05T20:00:00.000Z",
   "ended_at": "2026-08-13T20:00:00.000Z",
   "start_price": 50.36,
   "end_price": 50.36,
   "definition_version": 6
  }
 ]
}

Same grammar on scan, series, and webhooks; state reads take ?asof= for point-in-time answers.
