CoinAPI is a platform that provides crypto data through a cryptocurrency API. In this guide, we’ll walk through how to pull cryptocurrency data from CoinAPI directly into Google Sheets, using the free API Connector add-on. We’ll first get an API key from CoinAPI, and then set up a request to pull in cryptocurrency exchange rate details to your spreadsheet.

• Part 1: Get your CoinAPI API Key
• Part 2: Create your API Request URL
• Part 3: Enter values into API Connector
• Part 4: Notes and Expansions

1. If you haven’t already, navigate to https://www.coinapi.io/ and click Get a Free API Key
   
2. Fill out your details and click Get a Free API Key
   
3. A few minutes later you’ll receive an email containing your API key. Congrats! You now have access to CoinAPI. Keep this key handy as we’ll need it in a moment.
   

We’ll follow the CoinAPI documentation to access Bitcoin (BTC) exchange rates.

• API root: https://rest.coinapi.io/v1/
• Endpoint: exchangerate/BTC

Putting it all together, we get the full API Request URL:
https://rest.coinapi.io/v1/exchangerate/BTC

We can now enter all our values into API Connector and import Bitcoin data into Google Sheets.

1. Open up Google Sheets and click Add-ons > API Connector > Create New API Request.
2. In the Create Request interface, enter the Request URL we just created
   
3. Under Headers enter Key = X-CoinAPI-Key, Value = {your API key}
   
4. Create a new tab. You can call it whatever you like, but here we’ll call it ‘CoinAPI_BTC’. While still in that tab, click ‘Set’ to use that tab as your data destination.
5. Name your request. Again we’ll call it ‘CoinAPI_BTC’
6. Click Run and a moment later you’ll see a list of current BTC exchange rates in your Google Sheet:
   

1. Experiment with endpoints and query strings as described in the documentation to see other types of cryptocurrency data. For example, you can see a detailed list of all exchanges tracked by CoinAPI by entering https://rest.coinapi.io/v1/exchanges.
2. The free version of CoinAPI limits users to 100 API requests a day.
