How we can build a “Creative Commons” for API terms of Service, as a contract to automatically read, control and enforce APIs Terms of service between infrastructure and applications?\n\nIn order to scale technical, business and legal interoperability between digital infrastructures, the API ToS-CC project aims to build a “Creative Commons” framework for API terms of Service, as a contract to automatically read, control and enforce APIs Terms of service between digital infrastructure and applications. The terms of service for APIs represent a boundary object whose identification of specific clauses and degree of \”openness\” (on the model of Creative Commons licenses with different degrees of conditions of use) can work towards a better understanding and vigilance.
