+        Returns a temporary URL to download the signed Carta Manifiesto that matches the tax ID in the organization's uploaded CSD as a ZIP file.
+
+        The organization must have an uploaded CSD, and a signed Carta Manifiesto must exist for the tax ID extracted from that certificate. The URL grants access to the file while it remains valid: treat it as a credential and do not store it.
