Robust REST and WebSocket Trading API Endpoints
A trading API serves as the programmatic bridge between your automated trading algorithms and our matching engine. Our REST and WebSocket endpoints deliver microsecond execution speeds and granular control over complex order types.
REST API for Account Management
REST API endpoints are optimized for account management, historical data retrieval, and discrete order placement. By utilizing standard HTTP requests, your applications can securely query balances, generate tax reports, and execute trades with minimal overhead.
Our REST architecture is fully documented and adheres to strict RESTful principles, making it incredibly intuitive for developers of all skill levels. We support advanced order types including Trailing Stops, Iceberg orders, and Fill-or-Kill (FOK) mandates directly through the API. This level of control is essential for algorithmic trading systems that need to manage risk dynamically based on fluctuating market conditions.
WebSocket API for Real-Time Streaming
WebSocket API connections provide a persistent, bidirectional communication channel essential for high-frequency algorithmic trading. Instead of repeatedly polling the server, your applications receive instantaneous, event-driven updates pushed directly to your client.
Subscribe to live order book deltas, real-time trade feeds, and instant execution reports with sub-millisecond latency. Our WebSocket feeds are highly compressed and optimized to minimize bandwidth while delivering the massive data throughput required by professional market makers. When milliseconds dictate profitability, our WebSocket infrastructure gives your developer tools the competitive edge they need.
Unmatched Algorithmic Trading Performance Metrics
Algorithmic trading requires absolute precision, which is why our infrastructure guarantees 99.99% uptime and sub-millisecond execution latency. We process over 100,000 orders per second to ensure your strategies execute flawlessly even during peak market volatility.
Colocation and Direct Market Access
Direct Market Access (DMA) and server colocation drastically reduce the physical distance data must travel between your trading servers and our matching engine. For institutional clients and high-frequency trading firms, we offer dedicated cross-connects in premier global data centers.
By bypassing the public internet, your algorithmic trading systems experience zero jitter and absolute deterministic latency. This infrastructure is critical when deploying latency-arbitrage or aggressive market-making strategies where being first in the order book queue is the sole determinant of success. Our network engineers work directly with your team to optimize routing and ensure maximum performance.
Intelligent Rate Limiting
Intelligent rate limiting protects the overall health of the exchange while ensuring fair bandwidth distribution among all API users. Unlike rigid rate limits that stifle innovation, our dynamic system scales based on your historical trading volume and total account equity.
As your algorithmic trading volume increases, your API rate limits automatically expand, granting you the capacity to send more concurrent requests and subscribe to deeper order book levels. We also provide clear HTTP header responses indicating your current limit status, allowing your developer tools to programmatically throttle requests and avoid temporary IP bans during aggressive execution bursts.
Official Developer Tools and SDKs
Developer tools and official SDKs significantly reduce integration time by providing pre-built wrappers for our core API functionalities. We officially support and maintain libraries for Python, Node.js, Go, and Rust.
Python SDK
Python remains the dominant language for quantitative analysis and algorithmic trading due to its rich ecosystem of data science libraries. Our official Python SDK integrates seamlessly with Pandas, NumPy, and SciPy.
The library handles all cryptographic signature generation, connection pooling, and error retries out of the box. Whether you are backtesting a moving average crossover strategy or deploying a machine learning model to predict short-term price movements, our Python tools accelerate your deployment cycle from months to mere days.
Node.js & TypeScript SDK
Node.js is favored by developers building real-time dashboards and event-driven trading bots. Our TypeScript-first SDK provides complete type safety, enabling rigorous compile-time checks and excellent IDE autocompletion.
Leverage the asynchronous nature of Node.js to manage thousands of concurrent WebSocket streams without blocking the main execution thread. The SDK includes robust reconnection logic, ensuring your trading API connection remains stable even if localized network interruptions occur. It is the perfect choice for building custom web-based trading terminals.
Rust & Go SDKs
Rust and Go are the languages of choice for ultra-low latency, high-performance algorithmic trading systems. These compiled languages offer memory safety and execution speeds that rival C++, making them ideal for high-frequency market making.
Our Rust and Go SDKs are heavily optimized to minimize memory allocations and reduce garbage collection pauses. By utilizing these advanced developer tools, quantitative funds can squeeze every possible microsecond of performance out of their trading architecture, gaining a critical edge in the highly competitive crypto markets of 2026.
Enterprise-Grade API Security Features
API security features protect your automated trading infrastructure through granular permission scoping, IP whitelisting, and advanced cryptographic signing. We implement industry-leading OAuth standards to ensure your funds and data remain strictly under your control. Learn more about our full security infrastructure.
Granular Permission Controls
Granular permission controls allow you to adhere to the principle of least privilege when configuring your trading API keys. Instead of generating a single master key, you can create multiple keys with highly specific access rights tailored to different applications.
For example, you can provision a "Read-Only" key for your tax software, a "Trade-Only" key for your algorithmic trading bot, and completely disable withdrawal capabilities across all programmatic interfaces. This ensures that even if a server hosting your developer tools is compromised, malicious actors cannot siphon funds from your account. You can instantly revoke any key from your security dashboard with a single click.
Essential security practices for API traders:
- Never share secret keys: Treat your API secret like a password; never commit it to public code repositories like GitHub.
- Enable IP Whitelisting: Restrict API key usage to the static IP addresses of your trading servers.
- Set Expiration Dates: Configure temporary keys that automatically expire after a set duration for short-term testing.
- Monitor Usage Logs: Regularly review your API access logs to detect any unauthorized request patterns.
Advanced Cryptographic Authentication
Cryptographic authentication ensures that every request sent to our trading API is verifiably authentic and protected against man-in-the-middle attacks. We utilize HMAC-SHA256 signatures for all private endpoint interactions.
Each request must be signed using your unique API secret, combined with a strictly increasing cryptographic nonce. This prevents replay attacks where a malicious party intercepts a valid trade request and attempts to submit it multiple times. Our official developer tools handle this complex signing process automatically, ensuring your algorithmic trading operations remain secure without requiring deep cryptographic expertise from your engineering team.
Comprehensive Trading API Documentation
Comprehensive documentation is the foundation of effective algorithmic trading development, offering detailed endpoint references, code samples, and rate limit guidelines. Our developer portal is continuously updated to reflect the latest API versioning and feature releases in 2026.
Interactive API Reference
An interactive API reference allows developers to test endpoints directly from their browser without writing a single line of code. Our documentation portal features a built-in REST client where you can input your sandbox keys and instantly view the JSON responses.
Every endpoint is meticulously documented with expected request parameters, required data types, and exhaustive lists of potential error codes. This clarity dramatically reduces the debugging time required when building custom developer tools. Furthermore, we provide copy-and-paste code snippets for every endpoint in over a dozen programming languages, ensuring you can integrate our trading API into your stack within minutes.
Dedicated Sandbox Environment
A dedicated sandbox environment is crucial for safely testing complex algorithmic trading strategies before deploying them with real capital. Our testnet perfectly mirrors the production exchange, featuring simulated order books, live price feeds, and identical matching engine logic.
Developers can fund their sandbox accounts with unlimited testnet tokens, allowing for rigorous edge-case testing and stress testing of their applications. By validating your code in this risk-free environment, you can deploy your automated systems to the live market with absolute confidence, knowing they will behave exactly as expected under real-world conditions.
