# 9Router — Video Generation (xAI Grok Imagine) Requires `NINEROUTER_URL` (and `NINEROUTER_KEY` if auth enabled). See https://raw.githubusercontent.com/decolua/9router/refs/heads/master/skills/9router/SKILL.md for setup. Requires a connected **xAI account** in the 9Router 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`. | Endpoint | Purpose | |---|---| | `POST /v1/videos/generations` | text-to-video / image-to-video | | `POST /v1/videos/edits` | edit an existing video | | `POST /v1/videos/extensions` | extend an existing video | | `GET /v1/videos/{request_id}` | poll job status | Request fields (passed through to xAI unchanged — see https://docs.x.ai/developers/rest-api-reference/inference/videos): | Field | Required | Notes | |---|---|---| | `model` | no | `xai/grok-imagine-video` (prefix is stripped before upstream) | | `prompt` | yes for T2V | video description | | `duration` | no | seconds | | `aspect_ratio` | no | `16:9`, `9:16`, `1:1`, `4:3`, `3:4`, `3:2`, `2:3` | | `resolution` | no | `480p`, `720p`, `1080p` | | `image` | no | `{ "url": "https://… or data:image/…;base64,…" }` for image-to-video | | `video` | edits/extensions | `{ "url": "…mp4" }` or `{ "file_id": "…" }` | ## Examples Submit a job: ```bash curl -X POST "$NINEROUTER_URL/v1/videos/generations" \ -H "Authorization: Bearer $NINEROUTER_KEY" \ -H "Content-Type: application/json" \ -d '{"model":"xai/grok-imagine-video","prompt":"A cinematic tracking shot through a neon city at night","duration":8,"aspect_ratio":"16:9","resolution":"720p"}' # → {"request_id":"abc123"} (response header x-9router-connection-id: <id>) ``` Poll until done (echo the connection header back so the same account polls the job): ```bash curl "$NINEROUTER_URL/v1/videos/abc123" \ -H "Authorization: Bearer $NINEROUTER_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 ```bash 9router 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-9router-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 9Router — a `403`/`permission_denied` from upstream means the connected account has no video access.
