Kaiko API Platform Reference

Introduction

Kaiko provides live and historical institutional quality market data for digital assets. Our service retrieves and validates millions of trades each day from the world's leading cryptocurrency exchanges to deliver robust and reliable market data to financial institutions globally.

Kaiko currently provides two HTTP APIs:

Reference Data (Public)
Market Data (Authenticated)

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

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.

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.

Data Feed

Receive historical and on-going data directly to your cloud provider. If you purchased a monthly subscription of Trade Data, 10% Order Books, OHLCV or VWAP, your data will be delivered once a day to your cloud bucket. We support Amazon Web Services S3, Google storage, Azure blob storage, and other providers. Cloud storage services allow us to easily synchronize our data with you once a day.

Cloud providers offer extensive storage services that will help you store large amounts of data. This eases the integration setup to feed whatever system you choose to integrate the data with.

If you do not already have a cloud provider, we suggest working with Amazon Web Services which is a major provider with a strong track record.

AWS S3 - How to receive our data through

Open https://s3.console.aws.amazon.com/s3/buckets/
Create a new bucket in the region of your choice. We suggest calling the bucket kaiko-delivery-nameofyourcompany
We suggest you use the us-east-1 (N. Virginia) region unless you are already using a different region as your main presence
Leave the properties on the default setting, finish the review and click on 'Create bucket'
After creating the bucket, click on it and navigate to the 'Permissions' tab. Click on 'Access Control List' to set the right permissions.
Under Access for other AWS accounts, press Add account and use the following id: 4d6be087cf0b9ee7af2f8d8c51469c81bc711e68ee9c6be386aee2322abc8175
Check all the checkboxes for permissions and press Save
Ensure that the permissions dialog resembles the following:

Market Data API

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>

You must replace <client-api-key> with your assigned 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 commodity the latest version is currently v1

Buy/Sell, Maker/Taker sides

For trades, the way exchanges report on the type of trade varies greatly. Some exchanges only report whether a trade was a buy or sell, without specifying which side the trade is actually referring to. Others do specify the side the trade is referring to. With the following mapping, we try to rule out any ambiguous interpretation of the taker_side_sell field in our trade endpoints. This mapping is in reference to what the exchanges are reporting via their APIs and documentation, and, in some cases correspondence between Kaiko and the exchanges.

Maker side

The following exchanges report trades from the perspective of maker orders. In all below cases, it was the maker who was selling.

Exchange	Notation	Kaiko `taker_side_sell: true` equivalent to:
Binance¹	`"m":` `true, false`	`"m": true`
Coinbase Pro^{1 2}	`"side":` `"buy" or "sell"`	`"side": "sell"`
Gemini²	`"type":` `"buy" or "sell"`	`"type": "sell"`
ZB.com²	`"type":` `"buy" or "sell"`	`"type": "sell"`

¹ Explicitly stated in docs

² Confirmed by exchange

Taker side

The following exchanges report trades from the perspective of taker orders. In all below cases, it was the taker who was selling.

Exchange	Notation	Kaiko `taker_side_sell:` `true` equivalent to:	Comment
Bitfinex²	`"type":` `"sell" or "buy"`	`"type":"sell"`
Ethfinex²	`"type":` `"sell" or "buy"`	`"type":"sell"`

Gatecoin²	`way: "bid" or "ask"`	`way: "ask"`

  "timestamp": 1528996780303,
  "query": { /* ... */ },
  "data": [ /* ... */ ]
}

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.

Key	Data type	Description
`data`	`[] \| {}`	Response result data.
`message`	`string`	Error message, if query was not successful.
`query`	`{}`	All handled query parameters echoed back.
`result`	`string`	`success` if query successful, `error` otherwise.
`time`	`string`	The current time at our endpoint.
`timestamp`	`long`	The current time at our endpoint.

Pagination

Pagination Example

}

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.

Parameters

Parameter	Required	Description
`continuation_token`	No
`page_size`	No	Maximum number of records to return in one response

Errors

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.

HTTP error codes
