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 →

Use series /v2/series

Its history over time, on one aligned grid. Docs →

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=pre_earnings_drift" -d "transition=enter" -d "since=2026-01-10" \

  "since": "2026-01-10T00:00:00.000Z",
  "until": null,
  "limit": 2,
  "signal": "pre_earnings_drift",
  "transition": "enter"
 },
 "count": 0,
 "results": []
}
Spans — when it was true for one ticker (AAPL)
curl "https://api.tickerbot.io/v2/signals/pre_earnings_drift/AAPL/events" \
  -H "Authorization: Bearer YOUR_KEY"
Response (sampled 2026-08-18, trimmed)
{
 "as_of": "2026-08-18T00:25:22.662Z",
 "ticker": "AAPL",
 "signal": "pre_earnings_drift",
 "count": 0,
 "events": []
}

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