# HeyGen documentation

Research date: 2026-08-24

Documentation coverage: not-retrieved.

Reference index, not a mirror of complete vendor documentation. Retrieved pages do not prove the MCP works.

## What it does

AI avatar/video-generation platform with a documented sales-prospecting motion - batch-personalize one template into many prospect-specific versions (dynamic name/company/pain-point variables), with native HubSpot automation that generates and attaches a personalized video to a contact on lifecycle triggers (new lead, meeting booked, deal-stage change).

## Access and connection

MCP support: official

Access requirements: paid, pay-as-you-go. Public REST API billed from a prepaid USD wallet per feature (e.g., roughly $0.05/sec for photo-avatar video, ~$0.000667/sec TTS, $1.00 per avatar-creation call); no free API tier found for developers, though a solo operator can start with a small prepaid balance.

Authentication: OAuth - vendor states "connect your HeyGen account, no API key required"; generation draws down the premium credits already in the user's HeyGen plan rather than separate API billing.
