D2 Product Preview: How to build world-class APIs

As AI agents take on more and more work for us, they will need consistent, well-documented, programmable interfaces to accomplish the work we need them to do. In this world, every company must become an API company. But how do you build a truly great API, both for agents and human developers?

In this session, we'll cover the components of a successful API program, from API design and development, to rate limiting and debugging, all the way to delivering last-mile developer and agent interfaces like SDKs, docs, and MCP servers. You'll learn how API teams at Stripe, Anthropic, and more scaled up to become foundational API primitives of the Internet, and set a new standard for developer experience. You'll leave with an operational blueprint of a high-functioning API program at scale, one that ensures both agents and human integrators are consistently successful.
