Function address_utxos 

async fn address_utxos<Rpc: RpcMethods>(
    rpc: &Rpc,
    args: GetAddressUtxosArg,
) -> Result<Vec<GetAddressUtxosReply>, Status>

Fetches the UTXOs for a list of transparent addresses, at or above the given start height, at most max_entries of them.

Both limits are passed to the state query, so they bound the work the node does rather than just the size of the reply.
