Index API provides direct access to cryptocurrency market indices. It is designed for developers, analysts, traders, and financial institutions who require standardized, ready-to-use market indicators without the need for complex in-house computation.

Included Indices:

Volume-Weighted Average Price (VWAP) Index
What it is: Calculates the average price of a cryptocurrency asset weighted by its trading volume over a specified period across relevant markets.
Purpose: Provides insight into the asset's average transaction price relative to its trading activity. Commonly used for evaluating trade execution quality, identifying intraday price trends influenced by liquidity, and setting benchmarks.

Principal Market Price (PRIMKT) Index
What it is: Identifies the price of an asset sourced directly from the single exchange demonstrating the most significant market influence, typically determined by having the highest trading volume for that asset during a given period.
Purpose: Helps pinpoint where primary price discovery is occurring and understand the leading price indication for an asset amidst fragmented liquidity.

Volatility Index (CAPIVIX)
What it is: A specialized index designed to measure the market's implied or expected future volatility for specific cryptocurrency assets or the market overall. Conceptually similar to the VIX index in traditional finance.
Purpose: Allows users to quantitatively assess market risk, gauge investor sentiment (fear/complacency), and anticipate the potential magnitude of future price movements. Essential for risk management and derivatives pricing.

Key Features & Functionality
