ShellShock — Video Generation (xAI Grok Imagine)

Requires SHELLSHOCK_URL (and SHELLSHOCK_KEY if auth enabled). See https://raw.githubusercontent.com/theRizwan/ShellShock/refs/heads/main/skills/shellshock/SKILL.md for setup.

Requires a connected xAI account in the ShellShock dashboard — either Grok Build OAuth (SuperGrok / X Premium+ subscription sign-in) or a direct xAI API key from console.x.ai. The two are separate auth types with separate billing; the dashboard shows which one each connection uses.

Endpoints (async job flow)

Video generation is asynchronous: the POST returns a request_id immediately, then you poll until the job is done or failed.

Request fields (passed through to xAI unchanged — see https://docs.x.ai/developers/rest-api-reference/inference/videos):

Examples

Submit a job:

curl -X POST "$SHELLSHOCK_URL/v1/videos/generations" \
  -H "Authorization: Bearer $SHELLSHOCK_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"xai/grok-imagine-video","prompt":"A cinematic tracking shot through a neon city at night","duration":8,"aspect_ratio":"16:9","resolution":"720p"}'
# → {"request_id":"abc123"}   (response header x-shellshock-connection-id: <id>)

Poll until done (echo the connection header back so the same account polls the job):

curl "$SHELLSHOCK_URL/v1/videos/abc123" \
  -H "Authorization: Bearer $SHELLSHOCK_KEY" \
  -H "x-connection-id: <id from create response>"
# → {"status":"pending","progress":42}
# → {"status":"done","video":{"url":"https://…mp4","duration":8},"model":"grok-imagine-video"}
# → {"status":"failed","error":{"code":"…","message":"…"}}

Download: fetch video.url from the done response.

CLI one-shot

shellshock xai video \
  --prompt "A cinematic tracking shot through a neon city at night" \
  --output video.mp4
# options: --model --duration --aspect-ratio --resolution --image --timeout --port --api-key

Submits, polls with progress, downloads to video.mp4.part, atomically renames on success. Ctrl+C cancels cleanly; non-zero exit on failure.

Notes & limits

• Jobs are account-bound upstream: poll with the same connection that created the job (x-connection-id header, value from the create response's x-shellshock-connection-id).
• Creation POSTs are never auto-retried (a retry could create and bill two videos). Only a 401→token-refresh→single-retry is performed, which upstream rejects before job creation.
• Video models are tagged kind: "video" and are excluded from chat model lists and chat fallback combos.
• Grok Build subscription OAuth tokens are sent to the same api.x.ai/v1/videos endpoints as API keys; whether a given subscription tier includes video-generation quota is controlled by xAI and is not verified by ShellShock — a 403/permission_denied from upstream means the connected account has no video access.
