Announcements - Dividends API - Missing Data

I’m using the announcements API - “{start_date}&until={end_date}&symbol={symbol_id}

I cant get future data on dividends, only historical data.
For example: Walmart announced dividend on the ex-date of 2023-05-04, while using the above API, I cant find this dividend information.

Any suggestions ?
I’m using the paper-api and not the broker api, how can I get a key for the broker api and not the paper-api ?

Thanks !

Any update ?
Someone from Alpaca Team ?
