# /parameters-extraction

## Extract parameters from a prompt.

<mark style="color:green;">`POST`</mark> `https://api.brianknows.org/api/v0/agent/parameters-extraction`

Allows you to send a prompt to Brian and return all the extracted parameters from the prompt.

You can implement your own custom logic and decide how to use the extracted parameters in you app. For example, you could take the swap parameters and build an integration on a chain that is not currently supported by Brian.
