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/pullback" \
  -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/pullback/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 →

  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"q": "pullback", "target_url": "https://example.com/hooks/tickerbot"}'

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

}
Spans — when it was true for one ticker (GGT)
curl "https://api.tickerbot.io/v2/signals/pullback/GGT/events" \
  -H "Authorization: Bearer YOUR_KEY"
Response (sampled 2026-08-18, trimmed)
{
 "as_of": "2026-08-18T00:25:34.202Z",
 "ticker": "GGT",
 "signal": "pullback",
 "count": 2,
 "events": [
  {
   "started_at": "2026-08-17T23:57:35.916Z",
   "ended_at": null,
   "start_price": 4.157,
   "end_price": null,

  {
   "started_at": "2026-08-17T21:37:36.162Z",
   "ended_at": "2026-08-17T23:32:38.920Z",
   "start_price": 4.163,
   "end_price": 4.165,
   "definition_version": 6

}

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