You have a clear vision for your investing platform. You’ve mapped the user experience and know the features that will set you apart. Now comes the decision that matters most: choosing the right infrastructure.

It can be tempting to choose the first brokerage API suite that allows you to execute a trade, as it may feel like you’re making progress. But if these APIs connect to a legacy system that relies on overnight batch processing and force you to reconcile with a shadow ledger, your platform may never achieve true real-time capabilities — and you’ll know when you get access to the platform’s developer portal (assuming there is one).

 

Made by developers for developers

The Apex Developer Portal includes powerful tools built by engineers to help you understand how our technology is built and streamline your integration to Apex AscendOS™ our clearing, custody, and trading infrastructure. That’s why it’s easier than ever to onboard to Apex technology. But buyer beware — not every wealth management platform has so many robust, pre-built tools to help you get your job done more efficiently and effectively, or the breadth of products to power your investor experience.

As you look for the right set of technology and developer portal tools to build your differentiated investing experience, here are four features that can contribute to your team’s successful build.

  1. Play in a sandbox and don’t lose your work
    The pre-sales proof-of-concept work you do in a sandbox shouldn’t be lost when you’ve selected your tech provider. Instead, you should be able to migrate your projects to a UAT environment, which helps reduce the need to build and then build again.
  2. Accelerate your build with modular SDKs and recipes
    Look for a suite of modular SDKs with pre-written code in languages you use to help significantly reduce the amount of code you need to write.
  3. Solve problems on your schedule with an AI assistant
    What should you do when you encounter a problem outside of your tech providers’ office hours? If your business is following the sun, an AI assistant could provide detailed answers to your technical or operational questions. Look for a developer experience designed to support you — augmented by an AI assistant — whenever you’re working.
  4. Build for your future, not just for today
    It’s important to select a forward-looking technology foundation, preferably a cloud-native one, that can evolve with your business and the financial industry’s evolution — especially with the rise of AI tools, an area of focus at Apex. As you evaluate your options, consider how your choice will handle future opportunities:
  • How do you add different advising experiences and business lines — think robo, self-directed, hybrid robo, or advisor-led — as your firm evolves?
  • How will you integrate emerging AI tools to enhance your developer and client experiences?
  • Will your infrastructure handle a surge in volume, whether it’s another meme stock experience or a big policy move?

 

The Apex advantage for developers

In case you haven’t noticed, we’re huge advocates of a modern developer experience. That’s why we’ve focused so many hours on building the Apex Developer Portal to help empower your engineers to integrate with Apex AscendOS™. Here are just a few of the benefits of building with Apex.

  • Our Developer Portal is chock full of tools, including RESTful APIs, API documentation and quick-start guides, SDKs (in (Java, Python, Go, and TypeScript), recipes, sample code, white-label UIs, a dashboard, and a sandbox
  • The sandbox work you do during the proof-of-concept phase is designed to accelerate your implementation, giving you a head start as you move into the UAT environment
  • Our own suite of essential trading tools available via APIs include our own real-time ledger, rebalancer, Order Management System (OMS), Execution Management System (EMS), and more
  • Add additional functionality now or later, such as direct indexing, Apex Alts and the Alts Marketplace, and other modular services available vis API
  • Ask Ascend, our AI integration assistant,* is available online 24/7 with context-aware assistance to help developers get the information they need to proceed from exploring and tinkering in the sandbox to scaling, building, and testing in UAT environment
  • With infrastructure built on the Google Cloud Platform (GCP), the Apex developer experience uses modern frameworks and protocols that are designed to support your business for years to come
  • Build for day one and day one million with greater confidence because our infrastructure is proven reliable at scale, supporting over 22 million brokerage accounts. Apex can deftly handle surges in volume, account openings, and more — on a regulatorily compliant foundation.
