HeyGen Video Agent — OpenClaw Plugin

Adds HeyGen as a first-class provider for OpenClaw's built-in video_generate tool. Same interface every other video provider in OpenClaw uses (Google Veo, Runway, Kling, Wan, MiniMax, Dashscope) — now with identity-preserving avatar/presenter video.

Install

openclaw plugin install heygen

Set HEYGEN_API_KEY in your environment (get one at https://app.heygen.com/settings/api).

Quick start

const result = await video_generate({
  model: "heygen/video_agent_v3",
  prompt: "Hi team, here's the product update for this week.",
  providerOptions: {
    avatar_id: "<your-avatar-id>",
    voice_id: "<your-voice-id>",
    orientation: "landscape", // or "portrait"
  },
});
// result.url → downloadable .mp4

Avatar / voice ids: list from the HeyGen dashboard or the heygen-skills companion skill (which composes opinionated avatar/voice picking on top of this plugin).

When HeyGen vs other video providers

• Avatar-presenter / talking-head video → HeyGen.
• Cinematic / scene generation → Veo, Runway, Kling.
• Translation / dubbing → use HeyGen's translate APIs (separate skill).
• Real-time interactive avatar → HeyGen Streaming Avatar (separate surface, not this plugin).

Provider options

Field	Type	Notes
avatar_id	string	HeyGen avatar id; falls back to models.providers.heygen.defaultAvatarId.
voice_id	string	HeyGen voice id; falls back to models.providers.heygen.defaultVoiceId.
style_id	string	Optional style template.
orientation	"landscape" | "portrait"	Maps from aspect ratio. 1:1 rejected.
mode	"generate" | "chat"	Default generate. chat keeps full poll budget for interactive flows.
callback_url	string	Async webhook completion.
callback_id	string	Caller-supplied correlation id for the webhook.
incognito_mode	boolean	Skip retention on HeyGen side where supported.

Errors surfaced cleanly

• 401 → HeyGen API key missing or invalid
• 402 / quota → HeyGen credit limit reached
• Generate-mode + 8 consecutive thinking polls → fast-fail with a hint pointing at avatar_id / voice_id.
• failed status surfaces HeyGen's failure_message rather than a generic error.

Polling

Three-tier backoff: 5s × 6 → 15s × 12 → 30s until MAX_POLL_ATTEMPTS. Long renders (20–45 min) stay under typical HeyGen per-key rate limits.
