Best APIs for crypto

Best Cryptocurrency APIs

If you’re looking to automate your crypto trading and research operations, it can be hard to figure out where to start.

Some crypto APIs provide multiple functionalities, which means you can get more use out of them. But to work better and faster, it’s a good idea to combine multiple APIs for optimal performance in each of your tasks.

The thing is, there are hundreds of APIs available on the internet – each one with its own strengths and weaknesses – how do you choose?

Well, that’s why we’ve compiled this list for you.

Here, you’ll find a comprehensive list of cryptocurrency APIs – each one built for simplifying your crypto tasks, saving you time and most importantly money.

We’ve segmented this list into different categories based on what you want to achieve:

  • Buy/sell/send
  • Manage bitcoin wallets
  • Track current exchange rates
  • Access full nodes & block explorers
  • Find currency symbols
  • Get historical data

In each category, you’ll see a list of our API recommendations which you can use to achieve the corresponding task. At the end, we’ll introduce you to the various APIs in this list and explain why we chose them.

Buy, Sell, or Send

If you’re looking for an exchange API for trading crypto, your primary criteria should be stability/uptime, cost, trading features, and customer service. And based on those criteria, there are 2 exchanges that stand out:

These exchanges are much less popular compared to giants like Coinbase or Binance, but the trade-off is amazing.

Not only are these exchanges cheaper, but they’re also more secure and stable.

Both Coinbase and Binance have experienced a multitude of problems throughout their time – severe customer service lapses, unexplained downtime, vague user agreements – the works. People have lost millions of dollars because of these issues.

If you’re a day trader (or any type of trader, really), issues like these are unacceptable, and it’s in your best interest to look for something better. After all, it’s your money on the line.

That’s why we recommend using Gemini’s and Kraken’s APIs for buying, selling, and sending crypto.

In addition to the well-known exchanges mentioned above, there’s also many smaller exchanges that also have an API such as Kucoin, SimpleSwap, and Click here to see a list of all exchanges.

Manage Bitcoin Wallets

If you’re looking for an API to help you manage your Bitcoin wallet, many crypto exchanges offer that exact functionality. We recommend using these 3:

Gemini makes it into yet another category on this list, but for good reason. Not only is it a secure platform for trading crypto, it also gives you plenty of flexibility with what you can do with your wallet. Gemini also provides digital asset insurance, which protects you from things like security breach or hack, a fraudulent transfer, or employee theft.

Blockchain is a great option as well. Unlike Gemini, you can’t use Blockchain to trade cryptocurrencies. However, it does provide great functionality when it comes to wallet management, such as sending and receiving bitcoin payments, fetching wallet balance, listing addresses, and more. Use Blockchain instead of Gemini if you’re not interested in trading crypto.

Get Latest & Historic Exchange Rates

For avid crypto traders (and hodlers looking to do their homework before diving into a coin), it’s important to get the most data as frequently as possible for the cheapest price.

The best APIs for getting current/historic exchange rates tend to be pricey. But, if you look hard enough, you can get the data at a huge discount.

Here’s what we recommend:

These APIs are all great for collecting the high-quality, tick-by-tick data you need to trade in real-time as well as backtest your strategies against historical market data. You can also try popular market data APIs like CoinAPI or CoinMarketCap, but we’ve found these ones to be the most robust.

Network Explorer & Node API

NOWNodes is a blockchain-as-a-service that provides cryptocurrency enthusiasts and developers with reliable access to blockchain explorers and full nodes. The service has a free plan for up to 20,000 requests per day.

It’s a cost-effective solution for any crypto entrepreneur that wants to maintain their own network, as the service allows you to connect to 45 blockchains in one place with one API key.

NOWNodes provides scalability for any large tasks and their service is monitored 24/7 for uptime.

Find Cryptocurrency Symbols

If all you need is to retrieve the symbols available for trading in an exchange, many of the APIs we mentioned above provide that exact functionality.

Here’s what we recommend:

CCXT is an amazing library that provides rich functionality for doing any kind of cryptocurrency automation, including retrieving crypto symbols. If you’re looking to build a bot, consider using it. If you already plan on using Gemini for any of the other tasks, Gemini lets you retrieve crypto symbols as well.

These APIs both have endpoints that give you a sorted list of string symbols – all arranged in a neat pile for anything you need to do.

Our Crypto API Recommendations – and Why They’re Good


Gemini is one of the most secure cryptocurrency exchanges out there. And it being based in the US only adds an extra layer of comfort since the platform is completely local. The user-friendly UI is great as well.

Gemini offers both public & private APIs that let you:

  • Buy/sell/send
  • Manage bitcoin wallets
  • Find currency symbols
  • Get latest & historic exchange rates

If your main goal is to trade altcoins, perhaps look somewhere else. You can only trade 20+ of the most popular coins on the exchange. If, however, you’re more on the conservative side, Gemini’s coin offerings might be enough for you.

Some of Gemini’s APIs are private, but all you need to do to access them is create an account, log-in, and obtain your API keys. Here’s the official guide.


Kraken is the most trusted cryptocurrency exchange on the market. Most of their digital assets are held safely in cold wallets, so they maintain a high level of security. And, if you ever have any questions or concerns, their customer support is available 24/7/365.

Kraken offers both public & private APIs that let you:

  • Buy/sell/send
  • Manage bitcoin Wallets
  • Get latest & historic exchange rates
  • Find currency symbols
  • And so much more…

Kraken’s API is super flexible and offers a TON of features.  On the Kraken exchange, you can trade over 50+ coins. This is still less than Binance (which offers 150+ coins), but the stability and security is leagues better. If you’re not interested in trading anything other than the most popular coins, try Kraken.


CEX.IO is a regulated crypto exchange founded in 2013 with over 4 million users worldwide. Their crypto trading and exchange API offers two options, websocket & REST.

Their websocket API allows you to:

  • Access account balance
  • Subscribe to order books
  • View open orders, place new orders, cancel orders, and view order history

Their REST API allows you to:

  • Receive real-time price feeds and access price charts
  • View trade history and account balance
  • View your open orders by pair and cancel orders

Their REST API is better for working with your trade orders and their WebSocket API is better for placing orders and getting market data. Getting started with the CEX.IO API is easy due to their extensive documentation.

CCXT offers both public & private APIs that let you:

  • Buy/sell/send
  • Manage bitcoin Wallets

  • And so much more…

CCXT is an actual powerhouse when it comes to crypto research and automation. There’s a pretty steep learning curve, but if you’ve got the fundamentals, you can do a lot.

It’s not the most powerful API for crypto trading (which is why it’s not listed in the trading category), but when you need to grab some quick data to look at, it’s very helpful.
