# User designed revenue models

Solice allows users to opt into revenue generation, with revenue models they can design themselves. A simple revenue model would be to charge an entrance fee for access to a piece of LAND or a building. For example, an art gallery, arcade, live concert, and personal NFT collection hall could all be monetized with this model. 

Note that the revenue models are optional but not mandatory, LAND and building owners can also make the area free and accessible for everyone that simply wants to enjoy the game.

## 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.solice.io/the-metaverse/user-designed-revenue-models.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.
