## 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:

```
GET https://docs.expand.network/integrations/dex-and-dex-aggregators/0x-aggregator.md?ask=<question>
```
