Data

What is Trade Data?

Trade Data is a general term for tick-by-tick data, or all trades occurring on an exchange. Our Trade Data products consist of all tick-by-tick trade data, normalized and timestamped. We provide trade data for all exchanges and currency pairs covered by Kaiko. 

What is an Order Book?

An order book is a list containing all outstanding buy or sell orders for a specific currency pair, organized by price level. An order book identifies the amount of the currency pair being bid or offered at a specific price, known as the market depth. An order to buy is called a ‘bid’ and an order to sell is called an ‘ask’. The exchange’s matching engine pairs up bids and asks, resulting in a trade.

    All order books consist of Level 2 data. Our data is categorized in rows by: timestamp, order type (bid/ask), price, and amount. 

    Kaiko provides order book snapshots at various market depths: 

    • 10% Order Books: orders placed at +/- 10% of the mid-price
    • 1% Order Books: order placed at +/- 1% of the mid-price (available upon request)
    • Full Order Books: all outstanding market orders (available upon request)

      For the full definition of an Order Book, see Investopedia - Order Book Definition.

      What is Historical Data?

      Historical data refers to all available data up until a certain point in time. Kaiko guarantees all historical datasets contain data up to 1 day before purchase of our product. For example, if you buy All Historical Trade Data from the exchange Bitstamp, you will receive all trade data from the moment we began coverage of the exchange to a day before your purchase. 

      We offer Historical Data for all of our products.

      What is meant by 'bid' and 'ask'?

      A ‘bid’ can be thought of as the highest price a buyer is willing to pay for a certain amount of an asset. This is in contrast to the ‘ask’, which is the lowest price a seller willing to sell an amount of an asset. The difference between these two is called the ‘spread’. In an Order Book, the ‘bid’ and ‘ask’ price are always accompanied by the amount of the asset being offered. In our Order Book datasets, bids are denoted as ‘b’ and asks as ‘a’.

      Which exchanges and currency pairs do you support?

      Currently, we cover 31 Exchanges: Binance, Bitfinex, BTC38, bitFlyer, Bitstamp, Bittrex, bithumb, BitMEX, Bit-Z, BtcBox, BTCChina, Cex.IO, Coinone, Ethfinex, EXX, Gatecoin, GDAX, Gemini, HitBTC, Huobi, itBit, Kraken, Korbit, Mt.Gox, OKCoin, OKEX, Poloniex, Quoine, WEX, YoBit and Zaif.

      We provide data for over 5000 crypto-to-crypto and crypto-to-fiat currency pairs. We will provide a comprehensive and updated list of all currency pairs soon. For a full list of all covered exchanges and currency pairs, please send an email to hello@kaiko.com.

      Do you have data on futures?

      Yes. We currently offer data on Bitmex and OKEx futures and will be adding to that list soon. 

      Why are there different prices for different exchange data?

      Kaiko prices our datasets in proportion to the amount of data processed and stored. Due to several reasons, some exchanges contain way more data than others; thus, those datasets will cost more.

      Where do you get your data from?

      We get our data from the public APIs provided by the exchanges.

      If the exchanges' APIs are publicly available, why would I pay Kaiko for their data?

      Fair point. However, collecting, storing, and normalizing immense amounts of data from all different exchanges and currency pairs is quite a task. We aim to provide data of the highest quality and completeness available on the market, and that takes time and resources.

      How do you guarantee that the data is complete?

      We strive to provide the most complete and qualitative data on the market. However, we partially rely upon the exchanges’ API to ensure this. Due to downtime of these API's (for example, due to maintenance) we sometimes experience gaps in our data and cannot always guarantee 100% coverage. 

      We know that this can be problematic. That's why we are currently in the process of negotiating data distribution agreements directly with the exchanges in order to backfill past and missed trades. 

      Is it possible to backfill missing data?

      We are in the process of securing data distribution agreements with several major exchanges with the aim of backfilling gaps in the data. Customers having bought market data containing gaps will be notified when backfilling becomes available. 

      Should you encounter any gaps in the obtained data, please do not hesitate to contact us and we will try to find a solution in a timely manner.  

       

      Data Delivery

      How will the data be delivered to me?

      The data you buy from our store can be pushed directly to your Cloud Provider. This is highly recommended because we deal with immense amounts of data. We support Amazon Web Services, Microsoft's Azure, and Google Cloud among other providers. This is particularly useful for our subscription products, which allows us to push data to your cloud provider daily. 

      For instructions on how to set up your AWS to receive direct data pushes, please refer to the Data Feed documentation page. For other cloud providers, please contact us. We will walk you through the setup step-by-step. 

      Alternatively, we also offer the option to download your data through a download link, which will be available immediately after completing your purchase and payment. You will receive an automatic confirmation email containing the download link, which allows for the data to be downloaded up to five times.  

      Which data formats are supported?

      All data is delivered in the form of ZIP archives containing folders organized per cryptocurrency exchange, per currency pair or according to date. The files itself are in CSV. 

      Order Books, one CSV file per day and per currency pair with the following fields:

      Subscription Models

      What subscription models do you offer?

      We offer various subscription models, depending on the length and the granularity of data you require:

      • Start-up, Intermediate, Professional, and Enterprise tiered subscriptions
      • All data subscriptions include a daily delivery through cloud push (Data Feed), API access, and 3 months of historical data (additional historical access can be purchased upon request)

      How does payment and billing work for subscriptions?

      Kaiko uses recurring billing to charge subscription data once per month. 

       

      Pricing, billing and order process

      Which payment methods are supported? 

      We support Credit Card payments (Visa, MasterCard & American Express) and PayPal as traditional payment methods.

      Since we're a digital assets market data provider, obviously we also accept cryptocurrencies. You can pay in Bitcoin, Ethereum, Litecoin and Bitcoin Cash! We use Coinbase Commerce for this, so the integration is seamless. 

      What is the order process? 

      After you finished adding all the data packages you wish to download to your shopping cart, you can proceed to checkout. If you already have an account with us, you can log in to automatically complete your details (if provided). If not, you will be requested to register as a user. 

      Next, you can choose your payment method. If you choose for PayPal or Coinbase Commerce, you will be redirected to their platform to complete your payment. 

       

      Security

      What are your security processes?

      We take security seriously. Our processes are explained in our security program.

      Do you provide an SLA?

      Availability and reliability of our services, along with security, are standars we highly value at Kaiko. Even if we do not have a formal SLA in place (yet), you should still be able to expect a high degree of availability and know that our engineers are ready to respond in the the event of an unforeseen incident. Maintenance operations that might affect availability will always be communicated in advance to affected customers.
