Single-asset benchmarks that average the prices over a period of time to determine an average value and daily âcloseâ prices (as crypto is 24/7, "close" prices are always synthetic). They can be used for several use cases from settlement of derivatives contracts to asset pricing and valuation. More information on the specific rates can be found here.
Requesting multiple tickers at the same time
To configure multiple tickers in the same stream, provide the indexCode as a comma separated list eg KK_PR_BTCUSD,KK_AAVE_USD
Alternatively, use a wildcard by entering a * and you'll receive all tickers you have as part of you Kaiko subscription.
Fields
Field
Description
indexCode
The ticker identifying the rate.
commodity
The type of publication. Either real-time or fixings
interval
The time period in which transaction data are considered for the calculation of the rate. If a rate's calculation methodology has an interval of 15 seconds, startTime and endTime will be separated by 15s.
quote
The quote asset used for the rate denomination.
bases
The list of base assets included in the rate and their weight. For reference rates, this will always be a single asset.
exchanges
The exchanges involved in the computation. This list may change every quarter during the rebalancing period and depending on the new results of the Kaiko Exchange Ranking.
percentages
The different distribution levels included in the price computation.
price
The value of the rate in the quote denomination.
pairs
The list of pairs combined with additional details included in the computation.

This example demonstrates how to request historical data using replay. The maximum amount of data you can request for one replay cannot exceed a total of 24 hours in hours, seconds, and minutes.
Replay data is available on a 72-hour rolling basis and should only be used to retrieve missed data. If full history is required, please use Rest API or CSV deployment methods.
