Index Price Sources

Accurate and reliable index prices are crucial for our platform. We source index price data from multiple reputable sources via APIs to ensure robustness and reduce the risk of price manipulation and sustain availability. Accurate and up-to-date index prices are essential for Rails core services such as funding and trading metrics calculations.

To ensure reliability and availability, our system uses a multi-sourced cascading fallback approach for index pricing, detailed below:

Primary Source
Coindesk Aggregate Index API - CCIX
Our main source of index prices.

Backup Source 1	Backup Source 2	Backup Source 3
CoinDesk Aggregate Index API - CCCAGG	Hyperliquid Subscriptions API - Hyperliquid	Kraken's Ticker (Level 1) API
Used if the primary source becomes unavailable.	Acts as a secondary fallback to maintain price availability.	Acts as the last fallback to maintain price availability.
