Designing Scalable, Secure, and AI-Ready APIs
APIs are no longer just data delivery mechanisms—they are now the core interface between humans, systems, and AI agents. As cloud-native architectures evolve and AI becomes embedded in everyday software, developers must rethink how APIs are designed, secured, and scaled.
This session explores modern API design practices for building secure, scalable, and future-ready systems. You’ll learn how to make APIs machine-discoverable, agent-consumable, observability-friendly, and resilient to abuse—all while maintaining great developer experience.
We’ll cover practical patterns and architectural decisions that help APIs thrive in environments where LLMs, automation agents, and global-scale applications depend on them. Topics include contract-first design, intelligent versioning, agent-safe security, real-time observability, and developer portal strategies.
Whether you're building internal microservices or public APIs for third-party integrations and AI tools, this session will give you a solid foundation to build systems that can safely and efficiently serve both people and machines.
From REST to Reasoning Agents — Design APIs that power secure, scalable, and AI-integrated platforms across cloud, mobile, and intelligent edge ecosystems.
Why This Talk?
AI agents, LLMs, and real-time personalization systems are now API consumers—and traditional REST APIs aren’t enough. Designing APIs for the AI era means they must be:
Introspectable (so LLMs can discover how to use them),
Rate-limited and token-aware (to control misuse by autonomous agents),
Structured for automation (with machine-readable contracts),
and secure by default, as APIs become critical integration surfaces for AI pipelines, reasoning engines, and autonomous workflows.
This talk explores the most relevant API design principles, reimagined for today's multi-device, multi-model, multi-cloud world.
