Compare HeyGen API pricing across self-serve plans. See per-minute video costs, monthly credit allocations, and free tier limits. No credit card needed.
HeyGen’s self-serve (Pay-As-You-Go) plan lets you purchase USD balance when you need it — no monthly subscription, no commitments.
When you authenticate with an API Key (x-api-key header), you are billed under the API tier. Usage is deducted from your prepaid USD wallet.Check your balance at any time:
GET /v3/users/me → wallet
OAuth vs API Key: If you authenticate with an OAuth bearer token, usage is billed against your web plan, not the API tier. Check your web plan balance with GET /v3/users/me → subscription.Using an API Key is recommended for automation and integration workflows. API key authentication provides higher concurrency limits and is more flexible and powerful for programmatic use.
Cinematic Avatar (type: "cinematic_avatar", Seedance pipeline) is billed at a flat rate per video, not by duration. You choose the video length between 4 and 15 seconds via the duration parameter. Only 720p and 1080p are supported — 4K is not available for this endpoint.
