Market events - Polaris

Market events capture non-trade state changes such as funding updates, liquidation prints, and venue-level status transitions.

Common event types

The /events endpoint returns mixed event types:

trade: executed transactions
bar: OHLCV candles
datapoint: market state updates such as funding rates or liquidations
orderbook: order book snapshots or updates

Common datapoint labels

funding_rate: perpetual funding rate
open_interest: open contracts or positions
liquidation: liquidation event
index_price: mark or index price update

Example:

{
  "timestamp": 1767225600456000,
  "venue": "lighter",
  "symbol": "SOL-USD",
  "type": "datapoint",
  "data": {
    "label": "funding_rate",
    "value": 0.00017
  }
}
