Precision Equals Profit

In modern wealthtech, latency is risk. With Charles Schwab’s secure, OAuth-powered APIs, fintechs, advisors, and individual developers can access real-time account data, portfolio insights, tax documentation, and trading functionality. Whether you're building for RIAs via Advisor Services or creating a personal trading platform, your app needs developers who understand the stakes and move fast.

Execute Your Vision

Schwab's API suite includes FDX-compliant data aggregation, digital onboarding tools, ACH setup, tax document retrieval, and both individual and commercial trading APIs. Each product comes with its own onboarding and compliance requirements, including 3-legged OAuth, Schwab’s Data Accessor Agreement, and in the case of Advisor Services, pre-approval. Navigating this landscape demands technical depth and product-level thinking — both of which Deploi brings to the table.

Why Deploi

Deploi is built for clients who can’t wait another sprint. We move with speed, clarity, and zero fluff. Our API developers understand financial data flows, authentication schemes like OAuth 2.0, and compliance-first engineering. We’ll help you integrate with Schwab while designing user experiences that investors actually enjoy.

What We’ve Engineered

We built AlgoEdge, a high-frequency trading platform capable of processing millions of data points per second. It features real-time scanners, proprietary indicators, and a no-code strategy engine—all powered by a multi-database architecture for low-latency execution. We’ve also engineered full-scale account aggregation systems, custom tax tooling, trading dashboards, and secure client portals for wealthtech firms.

What to Look For

A Schwab API developer isn’t just a backend engineer. You need someone who can:

  • Implement secure OAuth 2.0 flows (including 3-legged auth)

  • Build scalable services to fetch balances, positions, and tax documents

  • Design workflows for account linking, ACH setup, and trade execution

  • Navigate Schwab’s production access process and API-specific constraints

  • Think like a fintech PM: balancing speed, compliance, and user experience

Cost to Hire

Deploi’s rates for Schwab API work start at $100/hour. Typical projects range from $10,000 to $75,000, depending on scope and compliance overhead (e.g. Advisor Services vs. Trader API for Individuals). We offer fixed-bid pricing for well-defined projects and can scale up with your needs.
