# Oracle-Priced Purchase

> Learn oracle account validation, freshness checks, price conversion, and slippage protection with a compact Anchor example.

The Oracle-Priced Purchase example sells a USD-priced item for SOL using the MagicBlock real-time
pricing-oracle account format. It is a focused starting point for any protocol instruction whose
amount depends on a live market price.

## What the example demonstrates

* binding program configuration to an expected oracle feed ID;
* rejecting prices that are not fully verified or are older than 60 seconds;
* converting a USD-denominated amount into lamports;
* enforcing a buyer-provided maximum to protect against price movement.
