Top 5 Crypto APIs for Developers
#CryptoCompare
CryptoCompare was founded in 2014 making it one of the most well established data providers in the list. What jumped out to me was their API documentation and playground which is unlike any other I have used before. I found the documentation extremely helpful when exploring which endpoints to use and how to pass the right parameters to get the data I was looking for.
On the free plan you can get real-time and historical pricing data for over 6000 assets across 300+ exchanges.
On the downside, you can’t use their free API for commercial purposes and you are capped at 100,000 calls a month. For some of you 100,000 calls might be plenty, however, if you’re one of the power users out there who needs millions of calls each month on a budget, then you’ll like the next API provider.
#CoinMarketCap
CoinMarketCap’s API is rather expensive and has much stricter limits than the other providers. The free tier gets you 10,000 calls but includes no historical data, which you will need for lots of use cases such as charting or backtesting crypto trading strategies. If you are looking for over 1 million calls a month and 1 year of historical data you will need to take out the professional plan that will set you back $699 a month.
#CoinGecko
The CoinGecko API is a winner for developers who are on a budget but still require lots of calls.
In terms of data it has a really broad coverage of assets and exchanges with over 450 exchanges integrated, which is more than any other provider. The API also has all the most important real-time and historical data sets such as; pricing, OHLC and volume.
One area that CoinGecko falls down on is their depth of data, as currently their API doesn’t offer trade or L2 order book data. Also, after a bit of testing, it was clear that the prices are not quite real-time and seem to be typically updated every 30 seconds or so.
#TheGraph
For the Ethereum and DeFi nerds TheGraph is a must-try! This GraphQL API covers all things Ethereum, including; lending, borrowing and yield farming rates, as well as basically any data on the most important DeFi protocols. Unfortunately, you can’t get market data from this provider.
Their playground was a little confusing at first but is good fun to use once you get the hang of it. What makes this API particularly exciting is its business model is unlike any API you have probably seen before… It’s powered by a token called Graph Protocol (GRT) that is used to incentivize their community to make the data more reliable by indexing the complex and dynamic data on Ethereum.

#Polygon
Polygon is a solid contender thanks to its superb value and granularity of data. For $49 per month you get unlimited calls and access all of their data; 10 years of history, trades and L2 order book data.
Polygon is the only API provider in this comparison that provides non-crypto data. In fact Polygon is first and foremost a traditional market data provider, covering equities from exchanges like NYSE and Nasdaq. So for those that dabble in crypto and traditional markets this is a great choice as you can get all your data from one API, which saves quite a bit of development time.
The downside of this is that their crypto coverage is less than that of the crypto specialist APIs. Polygon only integrates with around 15 crypto exchanges which means a lot of the most exciting coins are not available.
