The agent paradigm includes the notion that agents interact with services. This paper identifies the need for controlled access to such services, from the perspective of agent systems (and not as is generally the case by web service providers). Mediating between web service requests from (virtual) organizations of agents, the web service gateway proposed regulates (i.e., monitors and controls) web service access according to the SLAs and organizational policies that are in effect. In addition to a model for web service access regulation, an implementation of a middleware component for web services access regulation based on SOAP and described in WSDL is presented.
