## Libraries
### Address Elements
Address Elements works by targeting the input elements of your address form and using their values with Lob's **verification** and **autocomplete** functionality.
{% tabs %}
{% tab title="JavaScript" %}
[](https://github.com/lob/address-elements) [address-elements](https://github.com/lob/address-elements)
**Registration**
Create an account at [Lob.com](https://dashboard.lob.com/#/register) to obtain a **Live Public API Key**. The key is available in the [Lob settings panel](https://dashboard.lob.com/#/settings) and uses the format, `live_pub_*`.
**Usage**
Embed the Lob Address Elements script immediately before the closing tag in the HTML containing your address form. The script will autodetect your form and its inputs.
