Abstract

Embodiments generally relate to finding a service in a service infrastructure. In some embodiments, a method includes receiving a service lookup request, where the service lookup request includes an application program interface (API) specification for a service to be invoked, where the API specification defines at least one target input parameter and at least one target output parameter. The method further includes searching for at least one service that has an API specification that corresponds to the API specification included in the service lookup request. The method further includes determining a sequence of services if no service is found that has an API specification that corresponds to the API specification included in the service lookup request, where services of the sequence of services include API specifications that, in combination, correspond to the API specification included in the service lookup request; and invoking the services of the sequence of services.
