Self-serve
- From API key to your first video in minutes
- Every API — Avatars, Voices, Video Agent, Translation, Lipsync
- Batch APIs — up to 100 requests per call, webhooks included
- REST, CLI, and MCP
The video you imagine,
delivered into your system.
We orchestrate avatars, voices, images, editing, music, and assets into deterministic, repeatable renders, and deliver production-ready video into your own stack. From one video to batches of thousands on HeyGen Cloud.
Assistant
Tell us the job, not the video
Onboarding walkthroughs, partner training, guided support — if your team repeats it by hand today, it can run as a persistent, programmable presence. Describe the work and the assistant maps it to the endpoints that automate it — before you write a line of code.
Hey — what are you building? Give me the job, the audience, and the scale, and I'll map it to the right endpoints. Or pick one:
Architecture
One system layer between your application and the models
Problems
Built for teams who ship video from their own systems
PROBLEM 01
“We can update their lines as needed, without ever having to return to the studio.”
Miro’s product-education videos star digital twins of their real presenters — when the product changes, the same trusted faces re-record through the API, no studio day required.
Models

The models underneath
Avatar V
Avatar V
Digital Twin
Character consistency across every angle, expression, and video you create.
Avatar IV
Avatar IV
Digital Twin
A lifelike avatar trained from real footage — speaks any script, in any voice.
Video Agent
Video Agent
Idea to finished video in a single prompt — no scripting, no setup.
Get started
Two ways to build
Enterprise
- Upload consent for avatar generation at scale
- Higher concurrency and rate limits
- Reserved compute on HeyGen Cloud
- Custom workflows, built with a forward-deployed engineer in your stack
For agents
Agent ready by default
Every endpoint ships with an MCP server, llms.txt, and typed schemas — so Claude, Cursor, and your own agents can generate video without glue code.
