Top 6 API Brokers
After our latest hands-on tests, we recommend these brokers with a trading API:
What Makes These Brokers The Best for API Access?
Here’s why these platforms stood out in our API tests, from reliability and documentation to speed and integration options:
- FOREX.com is the best broker for API trading in 2025 - FOREX.com’s REST API provided reliable automation in our investigations; average execution speeds around 20 ms, and most trades filled under one second, ideal for algo strategies. Spreads on raw‑pricing accounts dipped to ~0.2 pips with ~$7/100k commission. Support for Lightstreamer streaming is functional but less polished than competitors’ endpoints.
- CEX.IO - During our latest tests, CEX.IO’s REST and WebSocket APIs proved dependable with near-instant execution on major crypto pairs. We saw sub-50 ms tick updates and minimal slippage thanks to deep liquidity. While there's no FIX support, order fills were reliable even during market swings, making it solid for automation-focused traders.
- Gemini - During our evaluations, Gemini’s REST, WebSocket, and FIX APIs came through with microsecond-level order routing thanks to its Equinix NY5 co-located infrastructure in Secaucus, NJ. We saw strong real-time data delivery and smooth execution on major crypto pairs. For best results, lightweight payloads and retry logic helped maintain consistency during peak trading activity.
- Dukascopy - Dukascopy’s JForex and FIX APIs came through with fast, reliable automation, and low latency (~12–15 ms to Frankfurt) thanks to their ECN access to the SWFX marketplace. Market-depth support and full tick history via REST further empowered us to build nuanced strategies. Robust integration and consistent fills made algorithmic deployment smooth and scalable.
- Zacks Trade - In our latest round of tests, Zacks’ public API delivered near-instant access to EPS, sales, target price, and ratings consensus for ~4,500 US stocks. The JSON/XML endpoints are easy to integrate. Queries returned full historical layers with average, high/low, SD for each field. Pricing is usage‑unit based, starting with free up to enterprise tiers.
- Coinbase - When we tested Coinbase’s REST and WebSocket APIs, execution was consistently stable on their AWS-backed International Exchange, with smooth real-time data delivery, even during periods of high volatility. The integration process was developer-friendly thanks to their sandbox environment. While not built for ultra-low latency in our view, the infrastructure reliably supported institutional-grade automation.

How DayTrading.com Chose The Best Brokers With API Access
For each broker in our toplist, we conducted hands-on testing of their API access. We evaluated connection reliability, speed, documentation quality, and overall user experience, focussing on the needs of active traders.
Our goal was to assess how well each API supports fast execution, strategy automation, and seamless integration, and we recorded our findings to rank the best options available.
How APIs Work In Trading
An application programming interface (API) is a set of programming code that requests data and sends instructions between software platforms.
APIs are becoming more and more widespread in a range of industries and the number of trading brokers with APIs is steadily growing from our research.
APIs essentially act as a communication bridge for information between a broker’s servers and custom software applications employed by the user.
APIs have several useful applications including sending orders from third-party trading software or receiving live or historical data. For example, an API can be used to connect a set of automated trading algorithms with your preferred broker’s trading platform.
APIs play an important part in many automated trading strategies. In the past, traders would have had to filter through opportunities on one platform and potentially place trades on another. Now that brokers with APIs are becoming more common, this process has been simplified.
Algorithmic trading via APIs allows users to exploit useful trading opportunities by placing instant, accurate trades, removing the need for manual supervision.
Using programming languages such as Python, traders can develop their own applications or complex strategies and automatically execute trades using their broker’s API.
There are two main uses for APIs in trading:
Third-Party Applications – Traders using third-party applications, such as MetaTrader 4, may need access to the broker’s API for pricing data and the ability to place trades.
Developer Applications – Using programming languages like Python, Java or C++, many short-term traders are now beginning to develop their own automated trading applications. APIs allow them to access a broker’s pricing data and place trades.
If you want to find more broker-specific information about a particular API, you should be able to find the API documentation on the firm’s main site. This will give you information on how to authenticate the API, what data is available, how to place orders through the API and other technical details.
Some brokers with APIs will also provide a library of pre-written code to make interaction easier. This will usually be in the broker’s native coding language. This library will usually contain a set of functions for placing a trade, allowing you to avoid writing your own and speeding up the development process.
Pros Of Trading With An API
- Automate Trading – APIs are essential for connecting your automation algorithms with your broker’s servers. This goes for fully and semi-automated trading strategies. Algorithmic trading is very useful to implement strategies that would be very difficult and time-consuming to do manually, like high-frequency trading.
- Historical Data – Automated trading systems require historical data. With an API, you can seamlessly obtain this information and store, analyze and use it to your liking. Traders often use historical data for backtesting strategies.
- Custom Indicators – APIs allow traders to automate their own trading signals and indicators. There are many libraries within various coding languages in which custom indicator solutions can be found.
- Create Custom Alerts – If you are looking for customized notifications sent to your email, you can use an API to retrieve stock prices, spreads or even the value of your portfolio and notify you when these fulfil certain conditions.
- Create Your Own Trading Terminal – If your broker’s trading terminal is not exactly what you are looking for, you can build your own custom terminal and use your broker’s API to populate it with data and implement trading functionalities.
Cons Of Trading With An API
- Steep Learning Curve – If you are new to coding, APIs can seem quite daunting. It is recommended you practise first with an API for a demo account before placing real trades. There are many tutorials online and brokers with APIs offer examples on their documentation to help you get started.
- Limits & Quotas – Brokerages will often limit the frequency with which you can use the API to avoid overloading their bandwidth. For example, they may limit how many trades you can do per minute or hour, how often you can fetch information or which historical data you can access. Ensure that your broker’s limits are enough for your trading needs and implement limits in your code so you do not exceed the allowed quota.
- Fees – Most brokers with API support offer them for free but, if you want to go over their established limits, you might need to pay a fee and some brokers might charge a commission on your profit only for using the API.
- Security – To access your broker’s API you will need a key, which acts as a password. However, there are different protocols for APIs and they all offer different characteristics, often with a trade-off between speed and security. Research the protocol used by your broker and the security measures they implement for a secure experience.
Getting Started With A Broker’s API
- Consider Your Strategy: Decide which trading strategy you will be using and write a simple version in your programming language of choice. Make sure you understand the requirements of your strategy – for example, consider how much historical data you will need, which will be your trading frequency, any third-party applications you’d like to use and which assets are you looking to trade.
- Choose The Best Broker With An API For Your Specific Needs: You will need to evaluate brokers according to their general features, as well as their API tools. Some of the characteristics to consider are countries where they accept clients, market access, security, fees and customer service. Furthermore, some of the API features you need to think about are:
- API Demo: Do they offer a demo account and can you access it via the API? This will allow you to test your code and strategies with low risk and ensure that a paid account will be a good fit for your needs.
- Coding Language & Data Formatting: Ensure the API works with a language that you are comfortable with and that the format of the outputted data can be well understood by your program. JSON is a well-known data format that can be read by different coding languages.
- Documentation: A well-explained API is a must, especially for beginners. Choose a broker that offers complete documentation with examples and code snippets to make the learning curve easier.
- Support: The broker’s customer support should also cover their API, so they can help with more technical questions or issues.
- Quotas & Fees: If a broker has a limit on API trading, ensure your trading needs are well within this limit or that you are happy to pay the corresponding fees.
- API Type: Do you prefer REST, WebSocket or SOAP APIs? They each have specific characteristics, though the differences may not be huge if you are just getting started.
- Open An Account & Register For The API: Open an account with your selected broker, ideally a demo account, and register for API access. You will then get a key that you can use to log in.
- Set Up The API & Test Your Strategy: Check that you can access the API with no trouble, try out the code examples provided and connect your strategy to the API. Also, link your API to any third-party software you would like to use. When you are comfortable, test your strategy. It is recommended you do so for a few weeks to fully de-bug any technical issues that come up and tweak your strategy if needed.
- Use The Trading API With A Live Account: Once you are happy with your broker and their API and your strategy has been tested, you are ready to go live. Always ensure you monitor your strategy and the API and do not hesitate to contact the broker’s help desk or trading community if you have any issues.
Bottom Line
Brokers with APIs and their use are becoming increasingly ubiquitous. They allow users to create custom terminals and implement advanced trading strategies through automation.
Having a good grasp of coding languages such a Python, Java and C++ will give you the edge when trading using brokers with APIs. However, there are numerous free online tutorials about coding and APIs and many good brokers that we’ve tested provide comprehensive documentation to help get you started.
FAQ
What Should I Compare When Looking For Brokers With APIs?
When starting with APIs, make sure you can test your code on a free demo account. Find out which coding language and format are used by the broker and ensure you are comfortable with them. Make sure the broker has comprehensive API documentation, as well as reasonable fees and limitations.
Do Brokers Charge To Use APIs?
Alongside regular brokerage fees, some firms we’ve tested place limitations on the information you can receive using their API. For example, you may only be able to update your live data once every 5 minutes. Brokers may also charge additional fees if you wish to increase the amount of information you can receive.
Should I Start Using My Broker’s API?
Trading using a broker’s API can have advantages for active traders that specialize in algorithmic trading and want to develop more complex strategies.
However, make sure you are aware that you will need to have at least basic to intermediate programming knowledge to start trading via an API.
