Making Requests
When interacting with Kaiko HTTP APIs, you are expected to pass two headers:
Accept: application/json: API responses will be in JSON format.Accept-Encoding: gzip: All our endpoints benefit from use of compression.
curl --compressed -H 'Accept: application/json' 'https://<api_hostname>/<endpoint>'
Timestamps
Input
import pandas as pd
pd.to_datetime(<timestamp>, unit='ms')
All time parameters are in UTC and returned in the following ISO 8601 datetime format:
YYYY-MM-DDThh:mm:ss.sssZ
For example:
2017-12-17T13:35:24.351Z
The "T" separates the date from the time. The trailing "Z" indicates UTC time.
Output
All timestamps are returned as millisecond Unix timestamps (the number of milliseconds elapsed since 1970-01-01 00:00:00.000 UTC). For metadata fields, times are also returned in millisecond-resolution ISO 8601 datetime strings in the same format as input for convenience.
Data Dictionary
Kaiko's Data Dictionary includes schemas, methodologies, data samples, and additional information about all data types we provide and the delivery channels they are accessible through. You can access the Data Dictionary here.
Market open and close
Digital asset exchanges operate approximately 24x7x365.
For daily aggregated data, the opening price is calculated as the first trade at or after 00:00:00 UTC. The closing price is calculated as the last trade prior to 00:00:00 UTC.
"taker_side_sell" Explained
We created the variable taker_side_sell to account for the variety of ways in which exchanges report trade direction. While the majority of exchanges report trade direction from the perspective of a "taker", some exchanges report from the perspective of a "maker", and others opt to exclude a buy/sell field entirely from their transaction data. We researched every single exchange that we cover to determine from which perspective they report trade direction. The result is a normalized variable called taker_side_sell which takes the value of either true or false.
We have built this variable under the assumption that a taker’s sell order will always be filled by a maker’s buy order and a taker’s buy order will always be filled by a maker’s sell order. Thus, it is possible to create a single binary variable that indicates whether a taker was on the sell side or buy side of a transaction, no matter from which perspective an exchange reports trade direction. taker_side_sell takes the value of true when a taker's sell order fills a maker's buy order and false when a taker's buy order fills a maker's sell order.
For Decentralized Exchanges (DEX) using Automatic Market Maker (AMM) protocols, the liquidity pool contract is considered the maker. The entity executing a transaction against the liquidity pool is the taker.
If an exchange does not appear below, it can be assumed that all data we provide is normalized correctly. For exchanges where we were unable to confirm as reporting data from either a taker or a maker's perspective, we have included the notation mapping from the exchange's trade direction field to our taker_side_sell field. This is necessary so that researchers who want to further study trade direction can make their own conclusions. For exchanges that classify trade direction differently or exclude the field entirely, we also include the notation mapping and a short explanation for how their variable differs.
Finally, we have made a couple of errors in classifying exchanges as "maker" or "taker", typically early on in the process of developing taker_side_sell. Rather than switch our trade reporting after years of data collection, we have simply marked exchanges where the inverse of the notation stated should be applied. For these exchanges, researchers should be aware that when taker_side_sell: false, the inverse should be assumed.
To read an in-depth explanation of this variable, read our post here.

Market Data API
General
Base endpoints
The base URL for the Market Data Endpoints is regionalized. We are currently offering endpoints in the US and in Europe:
https://us.market-api.kaiko.io/https://eu.market-api.kaiko.io/
Usage
Authentication
Request Syntax
curl --compressed -H 'Accept: application/json' -H 'X-Api-Key: <client-api-key>' \
'https://<api_hostname>/<endpoint>'
Each API lives under its own hostname. Clients must include an API key in the header of every request they make. The format is as follows:
X-Api-Key: <client-api-key>
Data versioning
Kaiko takes transparency and accountability very seriously. Therefore, our provided datasets are versioned. Dataset versioning is orthogonal to API versioning. Any potential breaking changes in results (e.g. semantical changes or corrections of historically incorrect data) will result in a new dataset version - no corrections or adjustments will be done in the dark. Addition of new data will not result in a new dataset version. Data is versioned on a per-base-data level.
The versioning is selected by selecting a base data set and a version. All current Market Data API endpoints take the commodity and data_version parameters.
By setting this to latest, you will get the most recent version. The returned version is always included in the query field and can be referred to if you would ever need to compare results, should we ever need to adjust historical data. Paginating over a request with version set to latest will preserve the current version across subsequent pagination requests.
We recommend using the most current version explicitly in production integrations as the latest label might move at any time to a breaking change. For the trades and order_book_snapshots commodities the latest version is currently v1

All API responses are in JSON format. A result field, with a value of success or error is returned with each request. In the event of an error, a message field will provide an error message.
An access object is also echoed back. It contains two ranges of timestamps:
access_range: The time range for which the Client has access to the APIdata_range: The time range of data the Client is authorized to access
| Key | Data type | Description |

}
For queries that result in a larger dataset than can be returned in a single response, a continuation_token field is included. Calling the same endpoint again with the continuation_token query parameter added will return the next result page. For convenience, a next_url field is also included, containing a URL that can be called directly to get the next page. Paginated endpoints also takes a page_size parameter that specifies the maximum number of items that should be included in each response. Only the first call should include page_size, all subsequent calls should only use continuation_token. Paginating over a request with version set to latest will preserve the current version across subsequent pagination requests.

This endpoint gives access to one month of historical 10% order book snapshots. The full endpoint returns all the following order book data: the snapshot itself (bids and asks), the depth of the order book (the cummulative volume of the base asset at 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.5%, 2%, 4%, 6%, 8% and 10% from the best ask and best bid respectively), the spread, the mid price and, when the slippage parameter is not empty, the percentage of slippage for a given order size, either calculated from the best bid/ask or calculated from the mid price. All data is returned in descending order.

This endpoint gives access to one month of historical 10% order book aggregated data. It returns metrics on the average depth of the order book (the cummulative volume of the base asset at 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.5%, 2%, 4%, 6%, 8% and 10% from the mid price), the average spread, the average mid price and, when the slippage parameter is not empty, the average percentage of slippage for a given order size, either calculated from the best bid/ask or calculated from the mid price for a given interval. For each interval, the aggregates are calculated by taking the average metrics of each snapshot within that interval. For example, the aggregated 1 hour spread is calculated by taking all spreads of each snapshot within an hour and calculating the average. All data is returned in descending order.

This endpoint is identical to the Full endpoint but only returns metrics on average the depth of the order book (the cummulative volume of the base asset at 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.5%, 2%, 4%, 6%, 8% and 10% from the mid price) per snapshot. For each interval, the aggregates are calculated by taking the average metrics of each snapshot within that interval. For example, the aggregated 1 hour spread is calculated by taking all spreads of each snapshot within an hour and calculating the average. The Full specific parameters (such as slippage, slippage_ref) are disabled but won't yield any errors when used. All data is returned in descending order.

This endpoint returns the price of any asset quoted in a Fiat currency within Open Exchange Rate. The USD price is calculated based on the path of the highest liquidity, with an additional step using forex rates to get the final fiat price. This means that, even though an asset might trade directly against all Open Exchange Rate currencies, the price might still be established by using cross-rates1. In cases where the most liquid path changed over time, this will be taken into account in the calculation of the price for each interval. To have an overview of what data was used to calculate the price, set the sources parameter to true. Setting the sourcesparameter to false (default) will yield a faster response time. By making use of the sort parameter, data can be returned in ascending asc (default) or descending desc order.
1: A cross rate is an intermediary currency pair that does not involve the target quote asset.

1: When paginating, these parameters should only be included in the first request. For subsequent requests, they are encoded in the continuation token.
Outlier Management
| Field | Description |
|---|---|
median_perc |
Computes the median of all prices and excludes values that are off a certain % from the median. This is the simplest and most intuitive strategy. As it makes use of the median, it's better suited against extreme outliers. Usage of outliers_threshold: 0.1 for 10% |
zscore |
Computes the Z-score of each data point and excludes the ones for which zscore > outliers_threshold, where outliers_threshold is specified by the user (i.e a good rules of thumb would be a value between 1.5 and 3.5). Z-score signals how many standard deviations away a given observation is from the mean. This strategy is more susceptible to extreme values, as it makes use of the mean. More details here |
modified_zscore |
Similar to zscore but using the median instead of the mean, and the MAD (median absolute deviation) instead of standard deviation. This makes it less susceptible to extreme values. Usage of outliers_threshold: generally between 2 and 4 |

DEX Liquidity
DEXs liquidity pools market data is composed of two API endpoints: liquidity events & liquidity snapshots.
- The liquidity events endpoint provides flows data about the mint & the burn (adds & removals) type transactions associated to tokens amounts registered on DEXs liquidity pools. This data is made available at a transactional level and at a block granularity.
- The liquidity snapshots endpoint provides the total amount of reserves per token, made available at a liquidity pool level for all the covered DEXs. Specifically for Uniswap V3, this data is also made available in a per tick level, and enables the users to visualise the distribution of liquidity across ticks, for every block and liquidity pool available on Uniswap V3.
Those data are made available historically and live by both endpoints, and all at a block-by-block granularity. The supported exchanges are Uniswap, Sushiswap, Balancer, and Curve.

No | boolean. If true, returns all pair prices which were used to compute the Value at Risk. (Default: false) |
data_version |
Yes | The data version. (v1, v2 ... or latest) |
This endpoint uses data from CEXs as well as DEXs.
Fields
| Parameter | Description |
|---|---|
var_time |
The time at which the VaR is computed. |
value_at_risk |
Composed of two fields: value and risk_level (the Value at Risk estimator at the specified risk_level.) |
additional_vars |
List of additional VaRs for standard risk levels. |
pair |
The constituent pair. (showing only when sources is set to be true) |
ref_price |
The reference price per asset. (showing only when sources is set to be true) |
date |
The date of the reference price. (showing only when sources is set to be true) |
Computation and constraints
Considering the volume of data points processed for the computation of each data point, some parameter constraints have been implemented in order to optimize computation time:
- The number of
basesmust be less or equal to 5 quantitiesandbasesmust have the same length- The order of
basesand their respective quantities must match - The pair
base-quoteshould exist for all base - The
risk_levelshould be between 0.9 (included) and 1 (excluded).
Derivatives Metrics
This API endpoint provides derivatives-specific data unique to futures, options, and perpetual futures contracts. We currently provide historical derivatives data - beginning in July 2020 - updated once per minute. List of currently 7 supported exchanges are as follows: BitMEX, Deribit, OKEx, Kraken Futures, Binance, FTX and Bybit. More to be added soon.
It is comprised of 3 endpoints: reference, risk, and price. The reference endpoint provides details of the contracts, including base asset, quote asset, contract size, contract size unit, expiry and strike price. The risk endpoint indicates data that can be used to analyze risks related with derivatives, such as open interest, funidng rates, and option greeks. The price endpoint shows the mark price, index price, and price (last traded price).
Reference
The reference API endpoint provides details of a contract, which is the smallest unit of derivatives trading in most cases. The details include base asset, quote asset, contract size, contract size unit for all the types of derivatives, expiry for futures and options, and strike price for options. You can find a list of instruments using a wildcard (*) in instrument. For example, using *-usdt as an instrument and perpetual-future as an instrument_class lets you find any pereptual future instrument whose base asset is usdt.
If you encounter an error message 504 Gateway Time-out while using this API endpoint, it means that the amount of instruments that you requested is too big to be loaded. In this case, please use the filter, such as base_assets, quote_assets or option_type, so that the amount of instruments would not go beyond the maximum output threshold.

Derivatives Analytics
Implied Volatility Smile
This analytics API suite provides calibrated implied volatilities extracted from options market prices. The implied_volatility_smile endpoint returns a volatility curve for a listed expiry date computed on a set of strike prices. The computation includes space interpolation and allows users to compute consistent volatilities on non-listed strikes. Implied volatilities for non-listed expiries will be coming soon.
For now, only the exchange Deribit is supported due to liquidity constraints linked to the computation.
List of currently supported assets: BTC, ETH. More to be added soon.
