A robust and performing technical infrastructure is essential but insufficient to ensure a sustainable thriving of digital environments. Both technical and legal stability are necessary to cherish for the mutual benefit of service providers, their users and society at large. This stability is crucial to ensure the robustness and competitiveness of digital value chains and the thriving of the European digital ecosystem. Against this backdrop, this report explores crucial organisational and legal aspects of managing and coordinating digital interactions through APIs. Specifically, the analysis describes API-related legal obligations and applicable law. The study also analyses the current practices of coordination and negotiation with their digital counterparts in eight different organisations. Finally, the work analyses the clauses and conditions encoded in 4K API's Term of Services documents (ToS) to evaluate if current ToS drafting practices foster or hinder the thriving of fair digital environments. This work aims to clarify relevant aspects (e.g., API actors' roles and functions, API-related rights and obligations) that should be considered when designing rights and responsibilities flows within digital chains and the ecosystem at large. }, title = {API strategy essentials for Public Sector Innovation: Legal and organisational perspective}, url = {}, doi = {10.2760/511499 (online)} }
