Why the SendShort API
If content is king, video is the empire. Whether you're building a world-class SaaS product or running an agency at volume, SendShort gives you the same rendering pipeline our editor uses — captions, reframing, B-roll, translations.
Generate AI-powered shorts programmatically from any source: a YouTube link, a client upload, or a file already sitting in your bucket. Enterprise-grade processing, no infrastructure of your own.
