API Reference / Market Metrics
Get Market Metrics By Symbols
getMarketMetricsIndex/market-metricsBase URL: https://api.cert.tastyworks.com (Sandbox) · https://api.tastyworks.com (Production)
Returns volatility and liquidity metrics for one or more underlyings in a single read-only request. Pass a comma-separated `symbols` query list (e.g. `?symbols=AAPL,FB,BRK%2FB`); each underlying is returned as a `MarketMetricInfo` object including IV index, IV rank/percentile, liquidity ratings, and per-expiration option implied volatilities. This is a snapshot endpoint.
