Hello HeyGen Developer Community,

I'm building a workflow using the Photo Avatar API and need to understand the exact credit costs for each operation to estimate my usage with the API Pro plan (100 credits).

My Workflow Steps:

1. Upload Asset (photo) via POST https://upload.heygen.com/v1/asset

   • Upload 2-3 photos per person

2. Create Photo Avatar Group via POST /v2/photo_avatar/avatar_group/create

   • Create one group per person

3. Add Looks to Group via POST /v2/photo_avatar/avatar_group/add

   • Add 1-2 additional photos to the group

4. Add Motion (Kling engine) via POST /v2/photo_avatar/add_motion

   • Apply motion to each look (2-3 per person)

5. Generate Video via POST /v2/video/generate

   • I know video generation costs: 0.15 credits per 30 seconds

My Questions:

1. How many credits does uploading a photo (step 1) consume?
2. How many credits does creating a Photo Avatar Group (step 2) consume?
3. How many credits does adding looks to a group (step 3) consume?
4. How many credits does Add Motion with Kling (step 4) consume per avatar?

My Use Case:

• 1 moderator (setup once): 2 photos + motion = reusable across projects
• Per project: 2 new participants, each with 2-3 photos + motion
• Generate 10-15 minutes of video per project

Understanding these costs will help me estimate how many projects I can complete with 100 credits.

Thank you for your help!

David
