Use the Videos API

Set MINIROUTER_API_KEY to your inference key. Each example starts a job, polls it and saves the MP4.

VIDEO_ID=$(curl --fail-with-body --retry 0 -sS https://api.minirouter.sh/v1/videos \
  -H "Authorization: Bearer $MINIROUTER_API_KEY" \
  -H 'Content-Type: application/json' \
  --data '{
  "model": "minimax/minimax-h3-max",
  "prompt": "A paper boat drifting down a rainy city street, cinematic.",
  "seconds": 5,
  "size": "854x480"
}' | jq -r .id)

until curl --fail-with-body -sS "https://api.minirouter.sh/v1/videos/$VIDEO_ID" \
  -H "Authorization: Bearer $MINIROUTER_API_KEY" \
  | jq -e '.status == "completed" or .status == "failed"' > /dev/null; do sleep 10; done

curl --fail-with-body -sS -o video.mp4 "https://api.minirouter.sh/v1/videos/$VIDEO_ID/content" \
  -H "Authorization: Bearer $MINIROUTER_API_KEY"

Retries are off, so a dropped connection cannot start a second job. The MP4 stays available for 24 hours after the job completes.
