Async video job proxy mirroring the existing image-generation layer split:
Next routes → src/sse/handlers/videoGeneration.js (auth gate, account
fallback loop, refresh persistence) → open-sse/handlers/videoCore.js
(transparent upstream proxy, 401 refresh-once/retry-once, secret sanitization).
- POST /v1/videos/{generations,edits,extensions}: byte-exact body forward
(JSON + multipart), request_id passthrough, Idempotency-Key forwarded
- GET /v1/videos/{request_id}: status/progress/video.url passthrough
- Register grok-imagine-video (kind: "video"); add "video" to MODEL_TYPE_TO_KIND
so video models stay out of chat lists (also fixes runwayml leak)
- 9router xai video CLI: submit → poll → atomic MP4 download
- No auto-retry of creation POSTs (billable jobs); rotate accounts only on
401/403/429; sanitize Bearer tokens + credential values from errors/logs

description: Generate videos via 9Router /v1/videos/generations using xAI Grok Imagine (grok-imagine-video). Async job flow - submit, poll request_id until done, download MP4. Use when the user wants to create, generate, or render a video, text-to-video (txt2vid), or image-to-video.

# 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.
