 The Crypto Price API (Price Index) provides more than just pair prices—it also includes [OHLCV (K-Line)](https://docs.bitquery.io/docs/trading/crypto-price-api/crypto-ohlc-candle-k-line-api/), Simple Moving Averages (SMA), Weighted Moving Averages (WMA), mean prices, and other key price-related statistics.
 While you can access the aggregated price for a single trading pair, the Price Index also supports cross-chain and cross-DEX aggregation, giving you a unified view of token prices across multiple ecosystems.
