## Executive Summary

Zapier's API program is in strong shape overall — discovery, design, and documentation parseability are all solid, giving partners and agents a reliable foundation. The two areas that need immediate attention are onboarding speed and agent-executable context: partners currently lack a fast, guided path to a first working call, and agents have no runnable, example-rich collection to build against confidently. Prioritizing these two gaps will compress partner activation time and give AI agents the concrete workflow context they need to integrate correctly without hallucinating.
