Build your own interface on proven trading infrastructure.
An API-first trading platform is one where all functionality — order placement, market data, account management, reporting — is accessible through structured APIs. The platform's own front-end, if it has one, is built on the same APIs available to external developers. There is no privileged internal layer that cannot be reached from outside.
For brokers and fintech companies, this means the trading infrastructure can power any client-facing experience: a custom mobile app, a web portal, a proprietary trading terminal, or an AI assistant. The back-end does the work; the front-end is chosen by the broker.
Building trading infrastructure is expensive and time-consuming. Order management, risk engines, connectivity to liquidity providers, regulatory reporting — these are not differentiators for most brokers. What differentiates a broker is the client experience, the product offering, and the brand.
An API-first platform lets brokers separate these concerns. The infrastructure is handled by the platform provider. The broker invests in what differentiates their product — the interface, the onboarding flow, the analytics layer — without rebuilding what already exists. Time to market is faster; ongoing infrastructure maintenance is handled by the vendor.
TraderEvolution exposes four API interfaces, each serving a different integration layer:
Client API (WebSocket + REST). The primary interface for building trading front-ends. Covers order placement and management, real-time market data, account and trade reporting, price alerts, and Auto-Invest plan management. WebSocket handles streaming data; REST handles request-response operations. Full documentation is available at the TraderEvolution API portal.
BackOffice REST API. Designed for integration with third-party systems on the broker's side — CRM platforms, payment service providers, KYC systems, core banking systems, and external risk management or business intelligence tools. Brokers use this API to automate account operations and feed trading data into their existing infrastructure.
FIX API. The standard protocol for institutional order flow. Used to connect professional clients, prime brokers, and liquidity providers. Supports both inbound order routing from FIX-based client systems and outbound connectivity to liquidity providers and exchanges.
MCP Server. A structured tool layer built on the Client API for AI agent integration. Exposes 31 tools following Anthropic's Model Context Protocol standard, enabling AI assistants and autonomous agents to interact with trading accounts through natural language or programmatic calls. See the MCP Server page for details.
