# Decision Engine

## Execute the Decision Engine

 - [POST /blaize/decision-engine](https://developer.zuora.com/zephr-api-reference/zephr-public-api/decision-engine/executedecisionengine.md): The Blaize Decision Engine can be invoked via the Public API to calculate an HTTP Response based upon Request-Level Rules created in the Admin Console. This functionality is built into the Blaize Dynamic CDN but the API variant is useful for CMS or edge side integrations.

## Retrieve the Decision Engine

 - [GET /blaize/decision-engine](https://developer.zuora.com/zephr-api-reference/zephr-public-api/decision-engine/getdecisionengine.md): For compatibility with CDN, any web headers (Referrer, User-Agent) will be accepted and passed onto the rule engine.
