MarketsIO API Suite

One API for All Your Real-Time Needs


MarketsIO APIs are designed for maximum performance, ease of use and flexibility. MarketsIO APIs deliver new, and improved workflows for both data and liquidity services delivering significant efficiencies.

The MarketsIO PRIME API provides low level, high performance capabilities and the MarketsIO EDGE API provides ease of use while maintaining high quality performance. 

The Pegasus MarketsIO API suite for the Thomson Reuters Enterprise Platform (TREP) is the most powerful, richest, and easiest to use suite of APIs that helps you to you to extract the maximum value from your platform investment, while simultaneously obtaining platform independence.  TREP has near universal use within capital markets and is currently the most functional Market Data and Enterprise Platform available to capital markets.

All traditional Market Data functionality (Interactive/Non-Interactive Providers, Posting and Subscription) is supported. Our innovative Dialogue Channels fully exposes the peer-to-peer capabilities of TREP allowing for a fully bi-directional message flow between applications creating new, targeted, efficient and controlled generic message solutions for cost savings and/or greater revenue opportunities. 

Development times are significantly reduced with MarketsIO APIs.  You can create a basic subscriber or publisher within a day or two using the PRIME API, and a basic subscriber or publisher can be functional within a matter of hours using the EDGE API.  Significantly reducing overheads and improving your time to market.  

Extensively Tested

We run over 600 automated tests per language to ensure that we provide you with code that you can rely on to run your business.

Break Vendor Lock-In

Don't be a hostage to vendor platform or data lock-in any longer.

Pegasus has the keys.

Make Change Easy

An application changing from one platform to another should be as easy as a configuration change.

The MarketsIO API suite provides platform optionality as a configuration change to empower you to dynamically make changes.

De-Risk API End of Life

Virtually every bank is facing significant risk with the APIs they rely on to run their businesses. We have confirmed that the majority of APIs in use at most firms are no longer supported, have been declared End of Life or are soon expected to be declared End of Life. 

There is an acute need to de-risk this massive API support exposure.

The MarketsIO API suite is your Enterprise API Abstraction to eliminate this risk.

Future Proof and Reduce Internal Development Costs

Adoption of a universal API abstraction has been the goal of many organizations.  An easy to use, standardized API across multiple platforms will give you stability and enable you to significantly reduce your development costs overheads and accelerate time to market for new features.  

The MarketsIO API suite delivers a framework to standardize across your enterprise domain, easily and efficiently. 

The MarketsIO API suite enables you to change APIs once and never have to worry about change or API End of Life ever again!
