# Address Book
{% hint style="info" %}
Adding incorrect withdrawal addresses, or tag/memo may result in the loss of your coins.
{% endhint %}
### Address Book
Users can use the *Address book* function to streamline, secure, and automate their cryptocurrency and fiat address management. The address book is used to manage both the counterparty and user’s own addresses. The platform enables users to save, whitelist, and manage both wallet addresses and bank details, reducing the risks associated with manual entry.
{% hint style="info" %}
To send funds to counterparties/third parties, the user can use Aquanow's *Pay* product. Users will see *Self* if they are not enabled for Payment products. If users are enabled for payment products, they will be able to see both *Self* and *Counterparty addresses* in the Address book landing page.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.aquanow.io/pay/features/address-book.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
