# DebtPreviewer (read-only)

This is a smart contract designed to abstract the `DebtManager` logic, it provides read-only functions ready to be consumed by Exactly’s web app.

**This contract has mainly 2 purposes:**

* Retrieve information about any account collateral and debt for any pair of markets in exactly.
* Allow accounts to preview their positions, simulating a leverage or deleverage to a certain ratio with a desired health factor.

Please be advised that the  `DebtPreviewer` contract has not undergone a formal security audit. As such, we strongly discourage integrations involving this contract, since it is exclusively intended for read-only purposes by the [Exactly Web App](https://app.exact.ly/). Using unaudited contracts for any other purpose may expose users to potential security risks or other unexpected behavior.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.exact.ly/guides/periphery-contracts/debtpreviewer-read-only.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
