# HeyGen adds an API for building cinematic avatar videos

By Steven Van · 2026-06-06

The API lets developers script avatar likeness and expression into a coding-agent video pipeline instead of using the app.

HeyGen's new **Cinematic Avatar API** lets developers keep an avatar's likeness while adding a wider range of cinematic expression, and build it into a video pipeline through a coding agent. The [announcement](<https://x.com/i/status/2062580376493793360>) frames it as an API-first way to script [HeyGen](<https://creatorstoolbox.com/tools/heygen>) avatar generation rather than working through the app.
