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: CoinAPI Notes and Expansions

PART 1: GET YOUR COINAPI API KEY

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.
   

PART 2: CREATE YOUR API REQUEST URL

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

PART 3: ENTER YOUR VALUES INTO API CONNECTOR

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 the following set of key-value pairs:
   

   X-CoinAPI-Key	{API Key}
   Accept	application/json

   Replace {Api Key} with your CoinAPI 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:
   

PART 4: COINAPI + GOOGLE SHEETS NOTES AND EXPANSIONS

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 with this URL:

   https://rest.coinapi.io/v1/exchanges

2. The free version of CoinAPI limits users to 100 API requests a day.
