# Signals

What signals exist, and who matches one right now — built-in and your own, in one catalog.

- **All signals** — `GET /v2/signals`
- **Ticker matches (live)** — `GET /v2/signals/{signal}`
- **Ticker matches (as-of)** — `GET /v2/signals/{signal}?asof=`
- **Subscribe (webhook)** — `POST /v2/signals/{signal}/subscribe`

## Where else a signal shows up

A signal *over time* lives in [Series](/docs/endpoints/series), the moments it flipped in [Events](/docs/endpoints/events), and authoring your own under [Custom signals](/docs/endpoints/signals/custom). To be pushed when a signal starts matching, subscribe it as a [webhook](/docs/endpoints/webhooks/create).
