API Pricing FAQs
What are the different ways to integrate with HeyGen?
HeyGen offer three integration paths: MCP for connecting to AI assistants like Claude without managing APIs, Skills for extending AI coding agents like Claude Code and Cursor, and Direct API for full programmatic control over video generation.
How does authentication work for each integration path?
MCP uses OAuth — users authorize via a consent screen with no API keys needed. Skills and Direct API both use an API key passed via the X-Api-Key header, generated from Settings → API in your HeyGen dashboard.
Are MCP credits and API balance the same?
No. MCP usage is deducted from your web plan's premium credit balance, whilst Skills and Direct API usage is deducted from your API dashboard balance. The two billing pools are independent.
