Trade Execution

Easily send order requests via a single endpoint, cancel one or all orders for a pair across exchanges, fetch your accounts, balances and trades via REST or listen for updates via our websocket streams.

Market Data

Get real-time order books, prices and trades via websocket and access latest and historical market data such as OHLCV for plotting candlestick charts or for backtesting your automated trading strategies.

Frequently Asked Questions

What can I use these APIs for?

Use cases range from mobile or web applications requiring real-time or historical cryptocurrency market data to high frequency algorithmic trading on top tier exchanges. Possibilities are unlimited so it’s up to you how you use them. Our goal is to provide fast, reliable and standardized access to all supported exchanges and your accounts.

Which exchanges and markets are supported?

As of today, we have integrations with Coinbase Pro (formerly GDAX), Binance, Bittrex, KuCoin, Poloniex, OKEx, Kraken, Bitfinex, Gemini, and Codex.

Several more are in progress (including Huobi, HitBTC and BitMEX) and will be prioritized by trading volume, growth, liquidity, and of course user feedback. All integrations are thoroughly tested and undergo a rigorous roll-out process to ensure compliance with our security and reliability standards.

What types of data can I access?

The APIs give you access to two types of data:

  1. Public market data – for prices, order books, trade history etc
  2. Private accounts data – for exchange accounts, balances, trades, orders etc

Is streaming data available?

Yes! The following data is available via websocket streams:

  1. Public market data – real-time tickers, order books, trades
  2. Private accounts data – balance updates and order status updates

Do you provide volume-weighted average prices?

Yes, VWAP across all integrated exchanges is available for historical and real-time prices. See documentation for more information.

Are there any rate-limits?

Yes, our rate limits are designed to protect our systems against a single entity consuming disproportionate amount of resources. Most users should never run into rate limits, however if your use case is particularly sensitive to rate limits or latency – please consider our institutional products.
