# Getting Started with Coin Metrics Data

Welcome! Follow the steps below to get started with using Coin Metrics data.

## 1. Set up Your API Key

Most of our data requires an API Key. If you want an API key, get in touch with us on our contact page: <https://coinmetrics.io/contact/>

We offer some data for free under our Community Data. For more information, go to: [Coin Metrics Community Data](/packages/coin-metrics-community-data.md)

Data coverage can be seen by plugging in your API key at [coverage.coinmetrics.io](https://coverage.coinmetrics.io)

## 2. Learn How to Use Coin Metrics Tools

Coin Metrics offers several ways to access our data.

### For Business Users

You can use our [Data Viz](https://charts.coinmetrics.io/crypto-data/) to create charts dynamically using a point-and-click interface without any code. To learn how to use the charting tool, see our data visualization guide.

[Data Visualization](/data-visualization.md)

You can directly download files from your browser by adding a "format=csv" in your HTTP request, i.e. `https://api.coinmetrics.io/v4/timeseries/asset-metrics?assets=btc&metrics=PriceUSD,FlowInGEMUSD&frequency=1d&pretty=true&api_key=<your_key>&format=csv`

On Google Sheets, you can use the `IMPORTDATA` function on the formula tab:

```
=IMPORTDATA("https://api.coinmetrics.io/v4/timeseries/asset-metrics?metrics=CapMrktEstUSD,SplyCur,PriceUSD,CapMrktCurUSD&assets=usdc&frequency=1d&limit_per_asset=1&format=csv&api_key=<your_key>")
```

For more information on exporting data, see the guide: [How To Export Data](/tutorials-and-examples/user-guides/exporting-data.md)

### For Developers

## 3. Use and Explore Coin Metrics Data

You can view examples of how to use Coin Metrics data in the [Tutorials and Examples](/tutorials-and-examples.md) section.

We recommend new users to read the following guides first to get a basic understanding of Coin Metrics data:

* [Python API Client Walkthrough](/tutorials-and-examples/tutorials/walkthrough_community.md)
* [Data Visualization Walkthrough](/data-visualization.md)
* [How To Export Data](/tutorials-and-examples/user-guides/exporting-data.md)

Refer to our more use-case-specific guides to make the most out of our data:

* [How To Use the Coin Metrics API Efficiently](/tutorials-and-examples/user-guides/how-to-use-the-coin-metrics-api-efficiently-http.md)
* [How To Migrate From Catalog V1 to Catalog V2](/tutorials-and-examples/user-guides/how-to-migrate-from-catalog-v1-to-catalog-v2.md)

## 4. Understand our Data

Coin Metrics data is divided into the following types of data:

* **Network Data**: Data sourced directly onchain, primarily from nodes maintained by Coin Metrics.
* **Market Data**: Historical and real-time data from the world’s leading centralized and decentralized (Labs) spot and derivatives crypto exchanges
* **Index Data**: Independent measurements of cryptoasset market performance and network activity
* **Reference Data**: Information about the properties of a token or other entity.
