# Get current market price

`GET /v4/data/prediction/markets/{id}/price`

/v4/data/prediction/markets/{id}/price

**100 credits per API call**

Current price snapshot for a single market. Returns per-outcome quotes (best bid / best ask / sizes), the implied midpoint, spread, last trade price and rolling 24-hour volume. Useful for ticker-style dashboards and pre-trade previews.

**Other notes**

*   Resolves the same `id` formats as `GET /markets/{id}` (Polymarket condition id or Kalshi market ticker).
*   `volume24h` is reported in the market's `volumeUnit` — `usd` on Polymarket, `contracts` on Kalshi.
*   `volume24h` and `volumeUnit` are `null` when the upstream does not expose a 24-hour figure.
*   `midPrice` and `spread` are `null` when either side of the book is empty.
