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 →
curl "https://api.tickerbot.io/v2/signals/short_volume_spike" \

Use scan /v2/scan
The whole market through a WHERE clause — this signal composed freely with any other column. Docs →

Use events /v2/events
The flag as a timeline: each edge as a point event, and the spans it stayed true. Docs →

}Same grammar on scan and webhooks. This column is live-tense only — it isn't historized, so ?asof= reads and series pulls don't carry it.
