# Oracle

We use Morpher's oracle. This is a pull oracle, which means that for every Flux transaction that you do, that needs collateral price information, you have to include a signed price message.

It's possible to set up your own Morpher oracle subscription, which you can get these messages from. [Learn how to using their documentation.](https://www.morpher.com/radix/docs)

You're also free to use [our API](https://flux.ilikeitstable.com/api-docs), which allows you to get such signed messages.
