# Get Historical Balance of any Crypto Wallet
> Learn how to retrieve the historical balance data of any EVM-compatible crypto wallet using the Mobula API. This guide provides a comprehensive walkthrough for accessing past balance records, offering insights into wallet value fluctuations over time.
Mobula API enables the retrieval of historical balance data from EVM-compatible crypto wallets. This tutorial will guide you through the process of fetching and analyzing the historical balance of a wallet.
### What you'll need
1. An EVM-compatible wallet address for querying.
2. An API key from the [Dashboard](https://admin.mobula.io) (only for production use, you can use the API without an API key in development mode).
### Walkthrough
Select the wallet address for which you want to query historical balance data. Optionally, decide if you want to filter the data by blockchain or specific time intervals.
Utilize cURL, Axios, or the Mobula SDK (Beta) to make the API request:
**Using cURL**:
```bash theme={null}
curl --request GET \
--url 'https://api.mobula.io/api/1/wallet/history?wallet=0x77A89C51f106D6cD547542a3A83FE73cB4459135&from=1650788304000&to=1651940430000'
```
**Using Axios**:
```javascript theme={null}
fetch('https://api.mobula.io/api/1/wallet/history?wallet=0x77A89C51f106D6cD547542a3A83FE73cB4459135&from=1650788304000&to=1651940430000').then(response => response.json())
.then(response => console.log(response.data))
.catch(error => console.log(error));
```
The API response will include detailed historical balance data, showing how the wallet's value has changed over time:
```json theme={null}
{
"data": {
"wallet": [
"0x77a89c51f106d6cd547542a3a83fe73cb4459135"
],
"balance_usd": 241.16725574204617,
"balance_history": [
[1650788304000, 0],
[1650788305000, 0],
[1650874705000, 40.94737444508439],
// ... other data points ...
[1651940430000, 47.36438419453997]
]
}
}
```
### Extending Your Insights
With the historical balance data, you can:
* **Track Value Fluctuations**: Observe how the wallet's value has changed over specified periods.
* **Identify Trends**: Spot patterns or significant events in the wallet's history.
* **Incorporate Data into Applications**: Use this historical data for financial analysis, trading strategies, or portfolio management tools.
