We’re all aware that digital currencies have recently attracted the interest of both institutional and ordinary investors. Over the last decade, cryptocurrencies like Bitcoin have risen to prominence as a new asset class with exceptional returns. The foundation of crypto-success stories is clearly wrapped in cryptocurrency APIs.
APIs enable a variety of enterprises to gain access to a wide range of resources and help them enter markets they might not have previously considered. These APIs also allow you to check real-time crypto data in order to help you develop a trading bot, do academic research on cryptocurrency, or learn to code with crypto data.
Checking market prices, keeping an eye on wallet contents, and even sending and receiving transactions are all possible with crypto APIs. APIs are also extremely useful for almost any blockchain or bitcoin-related project.
If you’re a dedicated cryptocurrency speculator, developer, trader, or someone who wants to do cryptocurrency research, you’ll find various APIs to choose from below. Many cryptocurrency exchanges have made their APIs public, allowing any dedicated developer to connect their platforms to them. Here are the top 10 cryptocurrency APIs for developers:
Top 10 Cryptocurrency APIs For Developers
CoinMarketCap, which was founded in 2013 and has received 150 million visits this year, is one of the most popular and longest-running data providers. Its primary goal, like CoinGecko’s, is to aid retail consumers in tracking coin values and managing their portfolios.
CoinMarketCap’s API is a little costly, and it has a few more limitations than other APIs. Its free tier allows users to receive 10,000 calls, but it lacks historical data, which is essential for many use cases, such as backtesting crypto trading techniques or charting.
Furthermore, if your goal is to make 1 million calls each month, you’ll need a year’s worth of historical data to sign up for the professional plan, which would likely cost you $699 per month. Despite the price, it is a complete API that covers 300 exchanges and the vast majority, if not all, of the major crypto assets.
TheGraph is the place to go if you’re a DeFi or Ethereum nerd. This GraphQL API covers everything from lending to yield farming rates to borrowing, as well as any other data on the most used DeFi protocols. Unfortunately, The Graph does not provide market data. Their playing area is a little complex at first, but once you get the hang of it, it’s a lot of fun to use.
TheGraph is interesting because of its business model, which is unlike any other you’ve seen. It is backed by the Graph Protocol (GRT) token, which is designed to motivate TheGraph’s community to make data more reliable by indexing the difficult and dynamic data on Ethereum.
CryptoCompare is one of the most well-known data providers on the list, having been founded in 2014. What’s more appealing is their API documentation and playing field, which are difficult to compare. When determining which endpoints to utilize and how to pass the required measures to obtain the data you require, the documentation is really useful.
Here you’ll find a tab called “Crytosheets,” which displays a handy Excel crypto data plugin that imports all of CryptoCompare’s data into Google Sheets or Excel. For researchers who aren’t familiar with APIs, this cryptocurrency API comes in handy. In terms of data coverage, CryptoCompare covers everything.
You can get real-time and historical pricing data for roughly 6000 stocks across 300+ exchanges with its free plan. For those who want to dig deeper into the analysis, the blockchain data, which includes daily metrics such as hash rate and transaction value of over 800 coins, is well worth looking into. The Websocket API also allows you to stream trades and L2 order book data.
It’s important to note that you can’t use their free API for commercial reasons, and you’re limited to 100,000 calls per month. Some of you may think this is a lot, but if you’re one of those power users that need millions of calls each month on a budget, you’ll like this.
Polygon is a reliable API provider noted for its data granularity and ability to make unlimited calls. For $49 per month, you can get unlimited calls as well as all of their data, trades, 10 years of history, and L2 order book data. Polygon is the only API you’ll find that offers non-crypto data.
This API is also the first traditional market data source to provide equities from both the Nasdaq and NYSE exchanges. Polygon should be your go-to choice for people who dabble in traditional markets and crypto, as it provides all the data from a single API and reduces development time. Its drawback is that its crypto coverage is a little less than that of the crypto specialist APIs. Polygon collaborates with only about 15 crypto exchanges, which means that many of the most appealing coins aren’t available.
CoinGecko is the site for developers who have a certain budget but also need a plethora of calls. You may acquire free access to this, and it has no total call limits as well as a rate limit of 50 calls per minute, which is plenty for most uses.
In terms of data, CoinGecko has the most exchanges and assets covered by any provider, with about 450 exchanges cooperating. The most important real-time and historical data sets, such as OHLC, pricing, and volume, are also available through this API. Their API currently does not give trade or L2 order book data, which is a drawback. Furthermore, following extensive testing, it has become clear that the prices are not real-time and appears to be updated every 30 seconds.
6. BraveNewCoin (BNC) API
BraveNewCoin is a cloud-based cryptocurrency API that provides a quick and reliable reference for historical and real-time crypto data from over 200 exchanges, covering thousands of marketplaces and assets. BraveNewCoin provides complete access to a variety of public and private APIs for the developer community and institutions. The API provides a volume-weighted spot price for over 1,500 cryptographic assets from across the global network of crypto exchanges in this case. BraveNewCoin is also known for providing a comprehensive history of crypto-asset market data across all products, such as Crypto Spot Rates, LX Program, Crypto Market Rates, and Market Cap Table.
BitCoinAverage is an open-source initiative that provides a weighted average of Bitcoin prices. It is equipped with many tools and aggregates volume and price data from several other exchanges for its measurements. Furthermore, this API is ideal for market analysts and watchers. With this API, you will have access to the free plan, which is strictly limited to 5,000 API requests each month. You will also receive three additional plans with different peaks. The most expensive plan, with limitless requests, will set you back $75 each month. With a one-second update frequency on the corporate plan and a 15-second update frequency on the free plan, Bitcointy will ensure that you can keep track of market rates accurately and quickly.
8. Bittrex API
Built on Bittrex’s cutting-edge technology, Bittrex is a dependable, secure, and innovative digital asset trading platform for crypto traders. It offers a unique section where users may use the Bittrex API to gain programmatic access to their Bittrex accounts and withdrawals, trade, and make deposits. It also employs the API key protocol for basic authentication and has a Pacific architecture. The Bittrex API completely supports JSON answer formats, URI Query Strings (CRUD), and XML request formats.
9. Poloneix API
Circle owns Poloneix, which is one of the largest cryptocurrency exchanges in the world. It provides APIs for connecting to the exchange via WebSocket and HTTP. Both provide access to public data as well as private account information. The public HTTP endpoint is easily accessible via GET requests, but the private endpoint is only accessible via HMAC-SHA512 signed POST requests made with Poloneix API keys.
10. Coin Base API
You may include bitcoin cash, bitcoin, litecoin, and ethereum payments in your app or website using the Coin Base API. It can create wallets and addresses for bitcoin cash, bitcoin, ethereum, and litecoin. One can easily sell/buy and send/receive bitcoin cash, bitcoin, ethereum, litecoin, etc. The Coin Base API allows you to safely store your digital currency while also retrieving historical and real-time price information and receiving notifications when payments are received.
