MX.3 APIs: Open, Secure, Future‑Ready

MX.3 APIs expose the full trade life cycle, from pricing and booking to risk analytics and settlement, across all asset classes.

• Each API is built around real-world workflows, embedding deep capital markets intelligence to deliver out-of-the-box access to MX.3’s best-in-class analytics and unified data model.

• Cross-asset, front-to-back coverage, whether equities, rates, credit, FX, or commodities. MX.3’s unified data model ensures all functions and asset classes interoperate seamlessly.

• MX.3 APIs are proven in production at financial institutions worldwide, with a growing catalog for continuous enhancements without disruption.

What can you do with MX.3 APIs?

• Custom trader tools: Easily build bespoke pricing sheets or trading dashboards in Excel or Python, pulling real-time prices and greeks directly from MX.3.

• Consolidated dashboards: Build firm-wide P&L and risk exposures views via real-time dashboards fed by MX.3 API data. No more patching together spreadsheets.

• Digital channels and portals: Integrate MX.3 analytics and services into client-facing portals, mobile apps or even chat assistants. Deliver new digital offerings powered by MX.3 in the background.

• Risk and operations automation: Automatically stream positions, valuations and market data from MX.3 to downstream systems. Eliminate manual file exports and ensure consistent data everywhere.

MX.3 APIs are built with modern, open technology standards that make integration easy and safe.

• MX.3 APIs are fully RESTful services, with JSON payloads and published OpenAPI definitions. Language-agnostic by design, they are easy to consume in any environment.

• Developers can plug into MX.3 using their preferred programming language or integration tools, with no proprietary adapters needed.

• Every call is encrypted (TLS), with authentication and authorization (OAuth2) and governed by MX.3’s fine-grained entitlements, so users and applications only access what they’re permitted to, exactly as in the core platform’s user permissions.

• Designed for enterprise-grade reliability, MX.3 APIs support high availability deployments and horizontal scalability to handle large transaction volumes. Built-in monitoring and observability give IT teams full visibility into usage, performance and operational health via out-of-the-box Splunk dashboards or OpenTelemetry-based third-party and custom solutions.

Whether on-prem or in the cloud, you get the reliability and control your IT teams demand.

MX.3 APIs are designed to be as friendly as they are powerful.

• For developers, the learning curve is short. Thanks to comprehensive documentation and a wealth of examples, even those new to Murex can become productive quickly. Standard REST/JSON design means you can work in familiar environments (whether Python, JavaScript, C# or others) and easily integrate MX.3 with modern frameworks or cloud services. Rapid prototyping is enabled through tools like the Developer Portal and downloadable Postman collections, so you can test and build without heavy setup.

• Business users can also use these APIs without deep technical skills. Many teams already work with familiar tools and lightweight scripting. MX.3’s intuitive JSON payloads make it easy to bring real-time data into their daily workflows. This opens the door for traders, quants and risk analysts to explore insights faster, test ideas and automate recurring tasks with minimal effort. When more advanced development is needed, they can rely on the resources available through the Developer Portal, including examples and guided tutorials. The entire experience is designed to help users and AI coding assistances get value quickly, whether they are experimenting with a first call or contributing to a larger integration.
