# Staking Yield Reference Rates ## Active Staking Yields The active single assets endpoint provides information on which staking yield rates that are currently being calculated by Vinter. ## Staking Yields Daily For each yield rate, Vinter calculates an end-of-day value. This value is the official value for each yield rate and is published at different times, specified by the index methodology. {% hint style="info" %} For the time being, the yield estimates are extracted from APIs or staking providers' websites at 9 AM London time. It allows for a long time period for data validation and incident management. The impact on data quality is low in practice thanks to the low frequency of updates on staking providers' websites. {% endhint %} Every yield rate series has a serial number as part of its symbol, whose description can be found below. Vinter offers both Annual Percentage Rate (APR) values as well Annual Percentage Yield (APY) values. If the yield rate is an APR the symbol will contain **apr** in its name. If the yield rate is an APY the symbol will contain **apy** in its name. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
