# Kalshi API

> Raw Kalshi data with platform-native fields like event_ticker, series_ticker, and taker_side.

These endpoints return **raw Kalshi data** directly from the Kalshi API without normalization. Use them when you need platform-specific fields that the unified API strips out.

## When to use native endpoints

| Use case                               | Endpoint                          |
| -------------------------------------- | --------------------------------- |
| Cross-platform dashboards, analytics   | Unified API (`/v1/markets`)       |
| Kalshi trading bots                    | Native API (`/v1/kalshi/markets`) |
| Event-level grouping by Kalshi tickers | Native API (`/v1/kalshi/markets`) |

## Platform-specific fields

| Field                                | Type    | Description                                         |
| ------------------------------------ | ------- | --------------------------------------------------- |
| `ticker`                             | string  | Kalshi market ticker (e.g., `KXBTC-26MAR28-100000`) |
| `event_ticker`                       | string  | Parent event ticker                                 |
| `series_ticker`                      | string  | Series ticker                                       |
| `yes_bid` / `no_bid`                 | integer | Best bid in cents (1-99)                            |
| `yes_ask` / `no_ask`                 | integer | Best ask in cents (1-99)                            |
| `yes_bid_dollars` / `no_bid_dollars` | float   | Best bid in dollars                                 |
| `volume`                             | integer | Total contracts traded                              |
| `open_interest`                      | integer | Open contracts                                      |

## ID mapping

Every unified market with `platform: "kalshi"` has an ID formatted as `kal_{ticker}`. Strip the `kal_` prefix to get the `ticker` for native endpoints.
