# Wolfram|Alpha integration

{% hint style="warning" %}
Wolfram|Alpha integration is available in the [direct download](https://soulver.app/download) version of Soulver.

Apple does not allow App Store apps to request API keys from users ("additional functionality must be unlocked via an in-app purchase" to quote App Review). 
{% endhint %}

Wolfram|Alpha is a web service whose goal is to provide access to all objective data. You can try it [here](https://www.wolframalpha.com/).

{% hint style="info" %}
Setup Wolfram|Alpha integration in Soulver's settings (Settings > Calculator > Wolfram|Alpha). 

You must provide Soulver with a valid Wolfram|Alpha "App ID" which you can create for free [here](https://developer.wolframalpha.com/access).
{% endhint %}

You can use Wolfram|Alpha from Soulver to look up specific pieces of numeric data. Just type the name of the metric followed by = ?

```
distance to the moon = ?
```

After a second, Soulver will insert the metric if it's available via Wolfram|Alpha

```
distance to the moon = 365,519 kilometers
```
