Getting a list of crypto currencies with supported networks

In Exchange/Pro API:
Get all known currencies | Coinbase Cloud - this gives us supported networks for each crypto currency

This is a public API endpoint (https://api.exchange.coinbase.com/currencies). Would this endpoint go away? If so, there seems to be no replacement in SWIC and Advanced API combo to get this information.

In SIWC, there is
Data API: Currencies | Coinbase Cloud but this end point does not give us any information on supported networks
