Generate a video - Hedra

Generate a video from text. To animate an image, add input.start_image using an uploaded file or a completed image job’s asset reference.

Submit a job

Set HEDRA_API_KEY as shown in the quickstart. This example submits to veo-3; its payload is not interchangeable with another model’s schema.

curl --fail-with-body -X POST https://api.hedra.com/v3/models/veo-3 \
  -H "Authorization: Key $HEDRA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"input":{"prompt":"A camera moves slowly around an industrial inspection rig","aspect_ratio":"16:9","resolution":"720p","duration_ms":4000,"quality":"fast"}}'

The 202 response contains a job_id. Follow the submit, wait, and download workflow, or use webhooks. Check output status before retrieving URLs. To estimate this request first, send its body to POST /v3/models/veo-3/estimate.

Inputs and limits

Inspect GET /v3/models/veo-3/openapi.json for accepted fields, defaults, and constraints. See Files and outputs for media references and Quality levels for models that expose a tier selector.
