API description

About the API:

This API will help you to detect the best arbitrage opportunities in different crypto exchanges. 


What this API receives and what your API provides (input/output)?

Example of a pair BTC/USD. 

Exchanges example: southxchange cex bitfinex bitstamp kraken bitfinex2 independentreserve gemini bitbay.


What are the most common uses cases of this API?


Arbitrage Profit: The user can develop a bot to perform calls to this API and, if an arbitrage opportunity is detected, execute trades automatically or manually for profit. Manual executions are risky as arbitrage opportunities are unlikely to remain for more than a few seconds. Optional arguments allow restricting searches only among exchanges where the user has accounts, increasing the call speed and trading feasibility.

Trading Signals: The user can set trading algos to enter long positions on the exchange with the lowest ask and/or short positions on the exchange with the highest bid, betting on mean reversion. It can also feed a high-frequency trading machine learning model if the pattern of arbitrage size or exchanges involved becomes a good prediction for short-term trends.

Product Value: The user can embed the API into a website, web app, or mobile app to increase the value of the product offered to his customers.


Are there any limitations to your plans?

Besides the number of API calls per month:

Free Plan: 5 requests per day.
