## Executive Summary

eBay's API program shows strength in developer experience broadly, but faces critical gaps in three areas that directly block partner and agent adoption: the API contract lacks the schema depth, security clarity, and worked examples that partners need to build with confidence; the program is effectively invisible to AI agents with no machine-readable discovery artifacts; and there is no runnable, executable truth for agents to ground integrations against. Closing the contract quality and agent-readiness gaps should be the immediate priority to unlock self-serve partner onboarding and reliable agent-driven integrations.
