+}
+
+data "stackit_service_accounts" "sas_default_suffix" {

+  email_suffix = "@sa.stackit.cloud"
+}
+
+data "stackit_service_accounts" "sas_default_suffix_sort_asc" {
+  project_id     = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+  email_suffix   = "@sa.stackit.cloud"
+  sort_ascending = true
+}
+
+data "stackit_service_accounts" "sas_ske_regex" {
+  project_id  = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+  email_regex = ".*@ske\\.sa\\.stackit\\.cloud$"
+}

+
+### Optional
+
+- `email_regex` (String) Optional regular expression to filter service accounts by email.
+- `email_suffix` (String) Optional suffix to filter service accounts by email (e.g.,`@sa.stackit.cloud`, `@ske.sa.stackit.cloud`).
+- `sort_ascending` (Boolean) If set to `true`, service accounts are sorted in ascending lexicographical order by email. Defaults to `false` (descending).
+
+### Read-Only
+
+- `id` (String) Terraform's internal resource ID, structured as "`project_id`".
+- `items` (Attributes List) The list of service accounts matching the provided filters. (see [below for nested schema](#nestedatt--items))
+
+<a id="nestedatt--items"></a>
+### Nested Schema for `items`
