# Product Overview
## About the Widget
The Coindisco Widget is a fully customizable crypto-buying component designed to fit seamlessly into any website or app. It provides flexibility for both **visual appearance** and **functional setup**, giving you complete control over the user experience.
### 🎨 Full Theming
You can fully adjust the widget's appearance to match your brand:
* A set of ready-made theme presets is available out of the box
* Light or dark themes are automatically applied based on the user's system preference
* Full theme customization for colors, fonts, and layout
### ⚙️ Functional Customization
Beyond design, you can configure what the widget offers to your users:
* Enable or disable specific **networks**, **tokens**, or **payment providers**
* Define which **assets, fiat currencies, and payment methods** are available
* Control defaults like purchase amount, wallet address, or network selection
This flexibility allows you to fine-tune availability per region, compliance requirements, or product strategy.
### 🔑 Simple Standard Parameters
For fast integration, you can start with **just one API key**.\
In this case, the widget works out of the box — no extra setup required. Developers can embed it instantly and expand customization later as needed.
### White Label API Integration
For partners who want a fully branded **“Buy Crypto”** experience, Coindisco offers a [White Label API](#white-label-api-integration).
\
This integration allows your application to communicate directly with Coindisco’s backend — you manage the UI, while Coindisco handles quotes, payments, and transaction logic.
\
It’s a powerful option for enterprises that require a fully customized design and flow.
### ⚡ Recommended: Use the Widget Customizer
While you can configure the Widget manually via URL parameters, the easiest and fastest way is to use our **Widget Customizer**. It provides a live preview of your configuration and automatically generates the final embed code.
