Hour One

Hour One is a generative-AI video company (an Insight Partners portfolio company, acquired by Wix in 2025) whose Studio / MakeReals API turns text and templates into AI presenter ("virtual human") videos programmatically. The REST API lets developers create videos two ways — Blueprint (render from an existing Hour One project template) and Dynamic (define scenes, transcripts, characters and voices directly) — then poll or receive HMAC-signed webhooks (video.ready / video.failed) on completion, generate voice previews, add translated subtitles in 18 languages, pull per-scene metadata, and query a video-creation analytics summary. Authentication is an api-key header for the video surface and an HTTP Bearer token for account/key/webhook management.

Hour One publishes 1 API on the APIs.io network: Studio API (MakeReals v1). Tagged areas include Company, Video, Generative AI, AI Video, and Media.

The Hour One catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Hour One’s developer surface includes documentation, API reference, getting-started guide, authentication, and 16 more developer resources.
