The cryptocurrency industry has attracted interest from investors, developers, entrepreneurs, and enthusiasts around the world. As Ethereum ERC20 tokens became more popular, the most fashionable trend was to create a token to auction within an ICO and be traded or used as a utility in projects. from 2017.
Today, development on the Ethereum blockchain continues to be popular; However, development using data from the cryptocurrency market is emerging as the new cryptocurrency gold rush.
Whether you are a cryptocurrency trader, speculator, developer, or someone interested in researching cryptocurrency, there are plenty of APIs to choose from. Fortunately, I have tested almost all of the best cryptocurrency APIs and the results are amazing.
Let’s discover the best cryptocurrency APIs for you in 2022.

Messari provides API endpoints for thousands of crypto resources. These parameters include trade, market data (VWAP), quantitative measures, and qualitative information. This is the same API that drives their web application.
Most of their endpoints are available without an API key, but they limit their rates. The free tier does not include redistribution rights and requires attribution and a link to their site.
In general, Messari is a good API for those looking to build custom solutions. Although their site has good information for traders, developing with their API can be difficult. Having a positive spotlight within the crypto community, I decided a few years ago to try my luck by following a Github repository called “messariapiexploration”.
The documentation was very easy to read and I quickly understood the basics of the API. Since then, I have used their data as a form of validation with Nomics to create an aggregated crypto data hub.

Nomics is a cryptocurrency data API focused on price, cryptocurrency market cap, supply, and all-time maximum data. They offer Candle / OHLC data for currencies and exchanges.
Additionally, they provide historical aggregate cryptocurrency market caps since January 2013. API Nomics is a resource for all developers.
However, they are a highly respected API in the cryptocurrency industry. An overall positive experience with Nomics leads me to discover what it has to offer. Nomics’ API is pretty straightforward to use, but when I started building crypto apps a few years ago, their API was a bit demanding for me.
If you want historical candlestick data for currencies and exchange rates, raw trade data without pauses, and/or order book data, you will need to pay for these services.

5. CoinMarketCap API
CoinMarketCap is commonly known to be the go-to for checking cryptocurrencies and token prices. CoinMarketCap provides API levels for individual users and businesses. the free plan has limits on the number of API calls you can make per month. The functionality is great for testing, but for those looking to build consumer-oriented apps, I suggest using an API with multiple options.
When I first discovered the power of crypto data, CMC was the first API I was exposed to. My first attempt to use their data was with a price prediction model, using their free historical data.

CoinGecko provides real-time price data, trade volume, tickers, exchanges, historical data, coin information and images, developer and community statistics, events, global markets, and CoinGecko Beam coins, and trade status updates.
With only 21 terminals this might not be the best option for merchants and businesses. Although CoinGecko is free, it is unlikely to meet the needs of traders and exchanges.
This API was the second API with which I started to develop projects. The challenge is that they do not have Python documentation. I think CoinGecko has the potential to be a free API; however, the community needs to step in and provide more documentation for the projects.
When I was doing the initial search for the API I should use for my projects, simply searching for “CoinGecko Python API” didn’t return a lot of results. Fortunately, I was able to find a wrapper on Github that helped me implement my project.

The cryptocurrency market continues to hit the main hedge, increasing exposure and becoming widely used by the masses. I think it’s important to start with an edge in developing applications and performing analysis within the industry.
Cryptographic data is a valuable resource that can be used to exchange, conduct research experiments, and leverage transparency for your organization. The future of crypto development depends on the number of projects that will continue to build innovative functionality within application programming interfaces in 2022.
