The Agent-Native API

When I said “all software becomes API,” I was describing the direction in which things were heading. What I didn’t fully specify was that the API itself would have to change, not incrementally, but categorically. The concept of what an API is transforms when the primary consumer shifts from a developer who studied the documentation to an agent that discovers capabilities at runtime.

This is a continuation of the design philosophy inversion we identified in the Interface — as explored in the interface layer wars reshaping consumer tech — Inversion analysis, specifically the fourth dimension: Static API Endpoint → Dynamic API Endpoint.

That dimension, it turns out, is where the most structural disruption is concentrated. Because the API is where software meets the agent. And the meeting is not going well.
