Corax data currently available through Eikon Data APIs corresponds to what you see in Capital Change Overview app available under the Events tab in Company View in Eikon. The greatly enhanced Corporate Events app was introduced recently. It combines capital change events and company events such as earnings releases, analyst calls and shareholder meetings and includes changes in listed shares, delistings and many more corporate event types not covered under Capital Change Overview. This enhanced corporate events data is currently only accessible via Corporate Events app in Eikon and cannot yet be retrieved using Eikon Data APIs. There's also no timeframe yet for when this data will be available through Eikon Data APIs.
