HeyGen Avatar / Video Agent

On Coinis, HeyGen Avatar / Video Agent is pay-as-you-go from one shared token wallet. Buy tokens once. Spend them on any model. No separate accounts. No monthly commit.

Avatar IV is a talking-head endpoint. You supply a script and a photo avatar. the model renders a presenter video at 720p, 1080p, or 4K. Video Agent is a full production endpoint. You supply one text prompt and it handles avatar selection, scripting, scene composition, and rendering automatically. Avatar IV gives you granular control. Video Agent gives you speed and simplicity for prompt-driven output.

No code. Create a free Coinis account, pick HeyGen Avatar / Video Agent, upload a photo and a script, and generate. 25 free tokens to start, no card.

Generation is fully asynchronous. On the standard tier, expect processing time of 5x to 10x the final video length. a 1-minute video typically takes 5 to 10 minutes. Enterprise plans receive priority queue access for faster processing. Poll for job status and retrieve the video URL once the job completes. Jobs still running after 24 hours indicate an error requiring support contact.

HeyGen Avatar IV is the model built for talking-head and avatar-driven video. Google Veo 3 and Kling v2 are cinematic prompt-to-video models optimized for scene generation, not presenter-style output. For a video where a human avatar delivers a script directly to camera, Avatar IV is the right fit. For cinematic B-roll, product environments, or creative scenes without a talking presenter, Veo or Kling are the available options on Coinis.

Photo Avatar creation is available as a per-call operation on the Pay-As-You-Go tier. Digital Twin creation in the app requires an Enterprise plan. Pay-As-You-Go users cannot create Digital Twins in the app. Once a Digital Twin or Photo Avatar is created, it can be used with Avatar IV generation calls on Coinis. Contact the HeyGen team directly for Enterprise plan access.

Avatar IV and Avatar V support 720p, 1080p, and 4K for both Photo Avatars and Digital Twin / Studio Avatars. The 4K tier carries a higher per-second rate direct from HeyGen. see the official docs at developers.heygen.com/docs/pricing for current 4K rates. For most sales and marketing videos distributed via web or social, 1080p is sufficient and more cost-efficient. 4K is worth considering for broadcast output or large-format display.
