Import CoinMarketCap Data to Google Sheets
CoinMarketCap is a cryptocurrency tracking platform. In this guide, we’ll walk through how to pull cryptocurrency data from the CoinMarketCap API directly into Google Sheets, using the API Connector add-on. We’ll first get an API key from CoinMarketCap, and then set up a request to pull in cryptocurrency exchange rate details to your spreadsheet.
- Part 1: Get your CoinMarketCap API Key
- Part 2: Create your API Request URL
- Part 3: Pull API data into Sheets
- Part 4: Handle Pagination
- Part 5: CoinMarketCap API +Sheets Notes
- If you haven’t already, navigate to https://coinmarketcap.com/api/ and click Get Your API Key Now
- Fill out your details and click Create My Account
- A moment later you’ll receive an email. Click on the email to verify your account, and you’ll be redirected into your new CoinMarketCap dashboard. Congrats! You now have access to the CoinMarketCap API. Hover over the API Key box in the top left and copy the key to your clipboard.
We’ll follow the CoinMarketCap documentation to access the latest crypto quotes.
- API root: https://pro-api.coinmarketcap.com
- Endpoint: /v1/cryptocurrency/listings/latest
Putting it together, we get the full API Request URL:
We can now enter all our values into API Connector and import CoinMarketCap API data into Google Sheets.
- Open up Google Sheets and click Add-ons > API Connector > Create New API Request.
- In the Create Request interface, enter the Request URL we just created
- Under Headers enter two sets of key-value pairs like this:
X-CMC_PRO_API_KEY YOUR_API_KEY Accept application/json
Replace YOUR_API_KEY with the value provided above in step 3.
- Create a new tab. You can call it whatever you like, but here we’ll call it ‘CoinMarketCap_Latest’. While still in that tab, click ‘Set’ to use that tab as your data destination.
- Name your request. Again we’ll call it ‘CoinMarketCap_Latest’
- Click Run and a moment later you’ll see the latest market data for all active cryptocurrencies in your Google Sheet:
Note that CoinMarketCap limits the number of records returned in each request. By default, only 100 records will be returned unless you use the ‘start’ and ‘limit’ parameters as described in their documentation.
To retrieve paginated records, add these ‘start’ and ‘limit’ parameters like this:
With API Connector, you can either set these up as separate requests or loop through them automatically with pagination (paid feature) for added efficiency, like this:
- Experiment with endpoints and query strings as described in the documentation to see other types of cryptocurrency data. For example, this URL will retrieve the latest global cryptocurrency market metrics:
- The free version of CoinMarketCap limits the number of accessible endpoints and number of call credits. Check the pricing page for details.
- If you’re looking for a more dynamic, ticker-like experience in Sheets, check out the API Connector custom function IMPORTAPI() for faster refresh rates.
