Microsoft announced at Build 2026's Day 1 Keynote that its Work IQ APIs will be generally available on June 16, 2026. If you build agents, work with Copilot Studio, or care about how AI connects to the data inside your organization, this one is worth understanding before it drops.

What Is Work IQ?

Work IQ is the intelligence layer behind how work gets done. It builds a semantic understanding of your business by continuously processing content from email, calendar, meetings, chats, files, people, collaboration patterns, and your line-of-business systems - producing a real-time model of how your organization actually operates.

That last part is the key distinction. This is not a search index or a document retrieval system. Work IQ provides intelligence you cannot get from the data alone. It knows who does what, how teams collaborate, and what is actually happening across the organization. That context is what gets handed to your agents.

Why Copilot and Copilot Studio Builders Should Care

The Chat API provides programmatic access to the full intelligence of Microsoft 365 Copilot - including citations - and programmatic access to agents in Copilot. For those building in Copilot Studio, the Tools domain is particularly interesting: Work IQ APIs collapse operations into just 10 generic tools with progressive disclosure through Model Context Protocol (MCP), so developers do not need to teach agents hundreds of data-specific tools. Fewer tools to wire up, faster time to a working agent. That is a meaningful improvement over the current state of affairs.

Security and governance - perennial concerns for enterprise deployments - are addressed at the architecture level rather than bolted on afterward. Agent operations are secure by design: data, context, and insights stay within the Microsoft 365 tenant trust boundary, and actions are auditable and discoverable, giving developers and IT the controls they need without adding a separate governance layer.

There is also a Copilot Studio connection in the pricing story. Microsoft is launching a new cost management dashboard in the Microsoft 365 admin center, and over time will bring in additional products that use Copilot Credits - including Microsoft Copilot Studio. Worth keeping an eye on as that pricing model matures.

The Four API Domains at a Glance

The Work IQ APIs are organized into four domains (seen in this article's feature image):

  • Chat - Programmatic access to the full power and intelligence of Microsoft 365 Copilot, including citations and access to agents in Copilot.

  • Context - Aggregates the content Copilot would use to respond to a query, returned in a format designed for agent consumption rather than synthesized into a human-readable response.

  • Tools - Agentic access to Microsoft 365 entities and actions through a simple set of verbs, covering tasks like sending emails, scheduling meetings, and uploading documents.

  • Workspaces - A place for agents to safely store intermediate state, files, memory, and progress while reasoning through longer-running tasks, all within the Microsoft 365 tenant boundary.

Pricing

Work IQ APIs use consumption-based pricing: a fixed component for Tools and a variable component for Chat and Context, denominated in Copilot Credits. Microsoft has published pricing details separately - check the official pricing page before building your budget assumptions.

Get Started Now

You do not have to wait until June 16. Developers can already start building through the public preview on GitHub ahead of general availability.
