Getting started with Note API Connector

You can get started in just a few clicks:

Web App: Access the platform directly via the Note API Connector Web App.
Chrome Extension: Install the Note API Connector Chrome Extension to use Note API Connector in Notion.

Once installed, simply authenticate your Notion account, grant the necessary permissions, and start creating API requests effortlessly.

👉 Follow the official setup guide for step-by-step instructions.

Create a Notion Database for Tracking Crypto Prices

We need to have a database where we import coins prices. In this database, we need columns Symbol , Name as text, and Current Price as a number. You can reuse the database from the previous guide.

Use the CoinGecko API

The CoinGecko API is perfect for fetching crypto prices, as it:

Offers a free tier with 50 requests per minute.
Requires no API key.

Before fetching data, you'll need to identify the CoinGecko API IDs for the cryptocurrencies you want to track. Visit the CoinGecko page of your desired coin and locate its API ID.

coins/markets endpoint allows getting various coins data , including the current price. For example if you want to get usd price for Bitcoin and Ethereum, you just need to call

https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids=bitcoin,ethereum

Integrate CoinGecko API with Notion

Create a new request by clicking Create request in Note API Connector. Paste the URL

https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids=bitcoin,ethereum

from previous step into the URL field and click the "Run" button.

At this stage, your Notion Crypto Tracker is ready to display real-time crypto data. Map fields:

symbol → Symbol
name → Name
current_price → Current Price

Then, click Save & Import and data should be imported in Notion database.

Link to Your Portfolio Database

If you already have a Portfolio Database as described in the previous guide , you can note your trades and link to current crypto prices.

Keep your portfolio up to date automatically with scheduled runs. Set it once and let your Note API Connector handle the updates for you.

Expand Your Crypto Tracker

Take your Notion Crypto Tracker to the next level by leveraging the CoinGecko API for advanced insights. Dive deeper into crypto trends with historical data, discover trending altcoins, and track metrics like volume and market supply for a comprehensive overview.

Historical Data: Use the /coins/{id}/market_chart endpoint to fetch historical prices. More info here .
Trending Coins: Leverage the /search/trending endpoint to track trending cryptocurrencies. More info here .
Altcoin-Specific Metrics: Add properties like Volume or Supply to gain deeper insights into altcoins.
