market microstructure and order book dynamics research
trading execution optimization
liquidity and lead-lag analysis
backtesting and optimization of trading strategies
full historical order book reconstruction at any given point in time
training machine learning models

Kraken Futures (Crypto Facilities)
We collect and provide data for all instruments & currency pairs available on given exchange with some exceptions caused mainly by exchanges API limitations. See historical data details.
For students and academic researchers we offer up to 70% discounts for all indie subscriptions. Contact us from your university email and we'll get back to you with discount code.
Yes, if you'd like to test the service (data quality, coverage, API performance etc) we offer generous free trials. Simply reach out to us and we'll set up test account for you in no time.
Our support team has in-depth knowledge of market data and exchanges' APIs peculiarities, programming and data analysis expertise. You get answer straight from the people that day to day job is overseeing and maintaining market data collection process and infrastructure.
For business subscriptions we provide dedicated communication channel (via Telegram Messenger) for your company where our team is on standby to answer any questions you may have.
You can access historical market data via API which provides raw data in exchange native format or download CSV datasets with tick-by-tick trades, incremental order book L2 updates, options chains, quotes and derivative tickers (open interest, funding, mark price, index price).
Data is available since 2019-03-30 for majority of the supported exchanges. See details.
Yes, see downloadable CSV files documentation for more details.
Any programming language that can communicate using HTTPS can communicate with our HTTP API.
Finally, locally runnable tardis-machine server with built-in local data caching, provides market data normalization, custom order book snapshots capabilities and real-time market data streaming support that connects directly to exchanges' WebSocket APIs. It provides both streaming HTTP and WebSocket endpoints returning market data for whole time periods (in contrast to Tardis.dev HTTP API where single call returns data for single minute time period) and is available via npm and as a Docker Image.
Historical market data provided by HTTP API can be accessed via HTTPS.
Locally runnable tardis-machine server provides both HTTP and WebSocket based APIs for accessing both historical and real-time market data.
Exchanges' market data WebSocket APIs are designed to publish real-time feeds and not historical ones. Locally runnable tardis-machine server's WebSocket API bridges that gap and allows "replaying" historical market data from any given past point in time with the same data format and 'subscribe' logic as real-time exchanges' APIs. In many cases existing exchanges' WebSocket clients can be used to connect to this endpoint just by changing URL, and receive market data in exchange-native format for date ranges specified in URL query string params.
We do not provide hosted real-time API which would incur additional latency and another SPOF, but instead we developed open source libraries that offer consolidated real-time normalized market data streaming capabilities and which connect directly to exchanges' WebSocket APIs, do not require API key and are completely free to use.
Contact us immediately and we will generate new API key for you.
Highly available Google Cloud Platform Kubernetes Clusters located in in London, UK (europe-west2 region) and Tokyo, Japan (asia-northeast1 region)
Two independent, geo-redundant, highly durable storage services
High performance API servers deployed across network of data centers around the globe
Yes, see enterprise deployment page for more details.
We do not have a formal SLA in place yet, but all infrastructure is set up to provide highest availability possible on both data collection and distribution side with geo-redundant setup. Both data collection services and public APIs are constantly monitored from multiple locations and our engineering team is immediately notified in case of any issue. We don't practice maintenance that would affect API availability, but in very rare circumstance if that would happen we'll communicate that in advance. If a formal SLA is something that your business require contact us.
