Get Signal Profile Metadata by ACI
View All Signal Number Validation & Identity Lookup APIs →Fetch unversioned public profile metadata for a known ACI (UUID). Returns plaintext fields only: identityKey, unidentifiedAccess, unrestrictedUnidentifiedAccess, capabilities, badges, and uuid (same as ACI).
