Most CoinAPI users take an API key and integrate market data directly into their own applications and systems. But not everyone wants—or needs—to build a custom application just to keep track of crypto prices.
Thanks to Rames Quinerie, a Notion Certified Consultant, there’s another option. His crypto portfolio tracker shows how CoinAPI market data can be connected with Notion to automatically keep cryptocurrency prices and portfolio information up to date.
Track your crypto in Notion
If you are interested in tracking your cryptocurrency investments, Rames Quinerie has written a detailed guide showing how to build a crypto portfolio tracker in Notion.
The setup combines three components:
- Notion for storing and displaying portfolio information
- CoinAPI Market Data API for retrieving current cryptocurrency prices
- Make for automating requests between CoinAPI and Notion
Instead of manually checking BTC, ETH, or other cryptocurrency prices, the automation retrieves the latest price data from CoinAPI and updates the corresponding assets in your Notion database.
You can then use Notion formulas and databases to calculate metrics such as your current portfolio value, growth, and earnings.
How the CoinAPI and Notion integration works
The workflow is relatively simple.
First, you create an Assets database in Notion containing the cryptocurrencies you want to track. Each asset has its ticker and a field for its current price.
Next, you get a CoinAPI API key.
The Make automation reads the cryptocurrency ticker from Notion and sends a request to the CoinAPI API. The returned price is then written back into the appropriate field in the Notion database.
You can choose how frequently the automation runs, giving you an automatically updated view of the assets you follow without having to refresh prices manually.
Go beyond crypto prices
The guide also shows how to turn this simple price tracker into a more complete crypto portfolio dashboard.
For example, you can create a separate Purchases database containing the amount invested, number of coins purchased, and purchase price.
By connecting it with the current price data from CoinAPI, Notion can calculate:
- current asset value
- investment growth
- profit or loss
- total coins held
- total earnings by asset
This means CoinAPI provides the market data, while Notion becomes the interface where you organize and analyze your portfolio.
Step-by-step guide
Rames’ complete tutorial walks through the setup step by step, including creating the Notion databases, getting your CoinAPI key, configuring Make, building the automation, and creating portfolio calculations.
It’s a good example of how CoinAPI can be used outside a traditional trading application or custom software stack.
If you want to build your own integrations, you can also find more examples in the how-to guides section of the CoinAPI documentation.
