Oakland, CA – October 21, 2026 – Magic Hour AI, Inc. has added a prepared-image workflow to its public AI UGC Ad Generator API. The endpoint, POST /v1/ai-ugc-ad, accepts an image, a script and a requested duration, with supported model and resolution options.
The workflow is intended for developers who already have the image they want to animate. For example, an application can submit a prepared actor-and-product composition with a spoken script. The endpoint returns a video project ID; the application then polls the existing video-project endpoint for status and downloads.
This endpoint does not compose an opening image. Teams that need a different composition must create that image separately before submitting the video request. The published contract lists Kling 3.0, LTX 2.5 and Veo 3.1, with model-specific durations, script limits and account restrictions. Unsupported resolution combinations are rejected rather than silently substituted.
The API contract and implementation establish the supported workflow, not an advertising-performance result. Generated material requires review for accuracy, rights, disclosures and suitability before commercial use. No speed, output-quality or conversion improvement is claimed.
