API & AI Addicts Day is a one-day Madrid conference on 28 October 2026 for enthusiasts and professionals interested in APIs and artificial intelligence. APIs and AI in one focused event Taking place in Madrid, Spain, API & AI Addicts Day brings two closely connected areas of modern technology into the same room. The conference is designed for people who want to explore the relationship between APIs,the interfaces that allow software and services to communicate,and the rapidly evolving field of AI. As AI becomes embedded in more products and workflows, APIs play an important role in connecting models, applications, data and external services. By focusing on both subjects, this event offers attendees a dedicated setting in which to consider the technologies together rather than as separate disciplines. Who is it for? The conference brings together enthusiasts and professionals, making it relevant to anyone with an active interest in APIs or artificial intelligence. That may include software developers, technical practitioners, product builders and other technology professionals, as well as curious community members following developments across these fields. No specific experience level or prerequisites are stated on the event page. Likewise, detailed information about speakers and individual sessions has not yet been published, so prospective attendees should check the registration page for future programme updates. What to expect API & AI Addicts Day is presented as a one-day conference, giving participants a concentrated opportunity to engage with its dual focus. Its defining feature is the combination of API and AI communities: a useful meeting point for people interested in how intelligent capabilities connect with software products, platforms and wider technical systems.
