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 →

Subscribe — webhook when a ticker starts matching
curl -X POST "https://api.tickerbot.io/v2/signals/min_open/subscribe" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"condition": "> 455.643", "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, ranked by this column
curl -G "https://api.tickerbot.io/v2/scan" \
  --data-urlencode "q=min_open IS NOT NULL" \

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": "min_open > 455.643", "target_url": "https://example.com/hooks/tickerbot"}'

Returns 201 with the created webhook object; deliveries carry the tickers matching the condition at each evaluation.

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.
