            </mymodule>
            <rewrite>
               <api>
                  <rest>MyCompany_MyModule_Model_Api_Rest_Client</rest>

class MyCompany_MyModule_Model_Api_Rest_Client extends OtherCompany_Core_Model_Api_Rest_Client  {

protected function _construct()

    highlight_string(print_r('_construct',true));
    exit();
} }

are the declared routes correct? or it may depend on the etc \ module file

where is specified I should write or

and in case the code depends on is compromised if I write only ?

Can you try this and let me know if works

<config>
<global>
    <models>
        <mymodule>
            <class>MyCompany_MyModule_Model</class>
        </mymodule>
        <mymodule_api_rest>
          <rewrite>      
             <client>MyCompany_MyModule_Model_Api_Rest_Client</client>
          </rewrite>
        </mymodule_api_rest>
    </models>
</global>

I think your issue is the config.xml that you've written. You generally would define your own model namespace "mymodule", then another node for the namespace you're rewriting ("api"), and put your rewrite in there. See below:

...
<models>
    <mymodule>
        <class>MyCompany_MyModule_Model</class>
    </mymodule>
    <api>
        <rewrite>
            <rest>MyCompany_MyModule_Model_Api_Rest_Client</rest>
        </rewrite>
    </api>
</models>
...
