# PSIDEX - Passive income DEX
## Introduction
Passive Income introduces the PSIDEX.
PSIDEX is the world's first frictionless yield DEX. It aggregates prices from a number of other decentralized exchanges to offer the cheapest route for trades, even if this means PSIDEX itself is not the cheapest route for a trade. This results in a better value trade for users of the PSIDEX compared to other exchanges.
The PSIDEX has been created to be faster, safer and more cost-effective than other popular BSC exchanges.

## 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://passiveincome.gitbook.io/psi-whitepaper/solutions-and-applications/psidex-passive-income-dex.md?ask=&goal=
```
`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.
