Can I generate a translated video with the original speaker's voice via the HeyGen API?

Yes. POST /v1/video_translate/translate accepts a video URL and a target language and returns a job that produces a translated MP4 with the original speaker's voice cloned into the new language. Poll the returned job id until the output URL is available.

How do I poll for video render completion through Jentic?

Run pip install jentic, search for 'check video render status', and execute against GET /v1/video/{video_id}. The response includes status (pending, processing, completed, failed) and, when completed, the video_url for download.

What rate limits apply to the HeyGen API?

Rate limits depend on the HeyGen plan tier (free, creator, team, enterprise) and are not exposed in the spec; the API returns HTTP 429 when exceeded. Implement exponential backoff and prefer template-based generation for bulk runs to reduce per-render overhead.

Can I create a custom avatar from a single photo?

Yes. POST /v1/avatar/photo creates a photo avatar from an uploaded image, while POST /v1/avatar/digital-twin produces a higher-fidelity digital twin from one or more images. Once created, the avatar id can be passed to /v1/video/generate.

Can I limit what my agent is allowed to do with the HeyGen API?

Yes. Jentic One is self-hosted by you, so your own rules decide which HeyGen operations and credentials the agent may use. You can scope it to read-only calls such as checking a video's status with GET /v1/video/{video_id} or listing avatars with GET /v2/avatars, while withholding generation operations like POST /v1/video/generate or POST /v1/avatar/digital-twin. Each operation is only available to the agent if you add it, and your stored API key is injected at call time rather than exposed to the agent.
