YouTube Opens Creator Performance API to Select Partners

Executive Signal Summary

YouTube announced the Creator Partnerships API at NewFronts, allowing a select group of third-party ad tech companies to access creator performance data (who watches what and for how long). The API is opt-in for brands and opt-out for creators, reflecting a controlled data-access model rather than an open data exchange. The move gives advertisers more granular signals for creator-led campaigns but is limited by creator opt-outs and brand permissions, positioning the API as an on-ramp to broader measurement capabilities rather than a final solution.
