## About HiAPI HeyGen Avatar IV

HiAPI is a unified API platform for AI models. This project page covers HeyGen Avatar IV, a talking-avatar video model that turns a single frontal face photo plus a script into a presenter video. You call it through the same OpenAI-style key you already use for image, video, audio and text models, so there is no separate HeyGen account to create or top up.

What it does:

- Accepts a face image and a script, returns a rendered talking-avatar clip.

- Exposes the model through HiAPI's async task API with per-call pricing shown on the model page.

- Sits alongside Kling, Seedance, Veo, Nano Banana and other video and image models behind one key.

Who it is for: developers shipping product explainers, localized marketing clips, or training videos who do not want to negotiate a separate contract with every model vendor.

Why it is useful: most teams end up juggling five provider dashboards, five billing relationships and five SDKs. HiAPI collapses that into one endpoint, one invoice and one set of rate limits, and lets you switch model versions by changing a model name instead of rewriting integration code.

Pricing: pay-as-you-go, no subscription. New accounts get free starting credit, and there is a Black Friday 2026 promotion running Nov 24-30 PT with bonus credit on top-ups and spend-back on image, video and audio usage.
