If you are here, this is probably why

You want HeyGen Avatar 4 inside your own product, behind an API key you already have
You make avatar clips occasionally, so a monthly credit allowance is spend you do not get back
You need the avatar step to sit next to image, voice and music on one balance and one bill
You need spending caps at the org, project and API key level because an agent is driving the render

The short version

It is HeyGen's model. Avatar 4 takes an image plus an audio track and is billed at $0.12/s, with the cost shown before you run it.
It is the only HeyGen model we carry -- their studio, avatar library and translation tools stay on their platform.
What changes is how you buy: no plan, no monthly credit allowance, and a balance that does not expire.
Make the audio track with any of our 8 voice models and drive the avatar with it, on the same API key.

When to go direct to HeyGen

We resell HeyGen. Sometimes buying from them directly is the right call — here is when.

We carry one HeyGen model. Their avatar library, instant avatar creation from a recording, and studio editor are the reason most people buy HeyGen -- and they are on HeyGen
Their video translation and dubbing products have no equivalent here
HeyGen publishes per-minute API rates ($1.00-$6.00/min, observed March 2026); if you produce avatar video at sustained volume, price your own duration mix against both before choosing
Enterprise avatar customisation, branded templates and team management are theirs, not ours
