For years, API teams invested in SDKs, client libraries, and documentation to make APIs easy for developers to consume. AI agents are changing that model.

Instead of relying on SDKs, AI agents can discover and invoke APIs directly from OpenAPI specifications. When your primary consumer is an AI agent instead of a developer, schema quality determines whether the right endpoint is selected, response payloads influence autonomous decisions, and traditional approaches to versioning and deprecation no longer fit.

In this session, you'll learn how to design APIs that work reliably with Microsoft Foundry agents and other AI agent frameworks—without rewriting your existing APIs.

What You'll Learn
- Why schema quality is the new developer experience—how agents use OpenAPI to discover and invoke APIs.
- Designing responses for AI agents—structuring payloads that enable reliable decisions while minimizing unnecessary data exposure.
- Rethinking versioning and deprecation—how dynamic API discovery changes compatibility strategies.
- Making existing APIs agent-ready—practical techniques for improving schemas, endpoint descriptions, and API design.
- Real-world failure modes—common mistakes that cause agents to select the wrong endpoint or misuse an API.
