## Discover Service IDs and compare with Builder

This endpoint requires the `getDeployedServiceVersion` API-key permission. To discover IDs first, use the [Builder service directory](<https://govform.com/resources/documentation/article/33-09-api-list-services-and-form-schemas>). Pass the Service ID without its library prefix to this QA or Production endpoint.

A current Builder definition may contain changes beyond the deployed version. Builder deployment history lists recent recorded releases and withdrawals; this endpoint checks what is currently deployed in the environment you call.
