Overview
apidays Paris is the flagship conference from the apidays family, and this year returns with the title “You don’t want your company to be digital, you want it to be programmable”. The future of innovation lies at the crossroads of APIs and AI. At apidays Paris: APIs Meet AI, explore how these transformative technologies are revolutionizing industries while tackling critical issues like data security, sovereignty, and sustainability. This conference is designed for developers, API strategists, and business leaders eager to stay ahead in the tech landscape.
In the rapidly changing world of technology, APIs and AI are transforming industries and driving remarkable innovation. The apidays Paris: APIs Meet AI conference is a crucial event for developers, API owners, tech decision-makers, and business leaders to explore how APIs are enabling scalable AI solutions while tackling significant challenges such as data protection, sovereignty, and sustainability.
Join us to discover our four main themes at apidays Paris:

Driving Innovation with AI-ready APIs: Learn to build and manage APIs that fuel next-generation AI applications.
Protecting Data with Secure APIs: Ensure strong security and governance to protect sensitive information.
Staying Sovereign with Your Own Data: Navigate sovereignty challenges with API strategies that comply with both regional and global regulations.
Ensuring Sustainability with Greener Software: Utilize APIs and AI to develop solutions that align with environmental and ethical goals.

From design to deployment, this conference provides actionable insights into creating resilient, scalable, and responsible API ecosystems. Connect with industry experts, gain hands-on experience, and discover how to unlock AI’s potential while shaping a sustainable future.
The variety and breadth of topics offered at apidays Paris are matched by how far OpenAPI reaches into the API ecosystem. OpenAPI has become the de facto API description language for API providers and is critically important for delivering high-quality and well-described APIs. Regardless of your chosen subject area, providing or consuming OpenAPI descriptions is vital to how you work with APIs.
The OAI track returns to apidays Paris for a third year. Knowledge of OpenAPI and our new specification Arazzo is a must-have for IT and business leaders who seek to drive their organizations forward through AI and APIs. Join us to learn more about how OpenAPI can provide you and your organization with a strategic advantage in adopting AI and how you manage your APIs throughout the entire API lifecycle.
