xai/grok-imagine-video with the Comfy Router API. xAI provides the model; Router gives it the shared authentication and request route below.
Quick start
Create a key at platform.comfy.org/profile/api-keys and export it asCOMFY_API_KEY. The Python and TypeScript snippets use the Comfy SDKs (pip install comfy-sdk, npm install @comfyorg/sdk); the cURL snippet is the same call over raw HTTP.
Model ID: xai/grok-imagine-video
Endpoint: POST https://api.comfy.org/v2/models/xai/grok-imagine-video
Schema
Input
Router has not published an authored input schema for this model yet:
GET /v2/models/xai/grok-imagine-video/openapi.json returns an open object with x-comfy-input-schema-authored: false. Router forwards the body to xAI unchanged, so xAI’s own API reference is authoritative for the request fields, and nothing is validated server side.Output
string
If the request was blocked by input moderation, contains the block reason
string
The model used to generate the video
string
Status of the deferred request: “pending” or “done”Possible values:
pending, doneobject
Usage information for the video generation request
integer
The cost of this request expressed in USD ticks. One USD cent equals 100,000,000 ticks, so one US dollar equals 10,000,000,000 ticks.
object
A generated video from xAI
integer
Duration of the generated video in seconds
boolean
Whether the video generated by the model respects moderation rules
string
Download URL for the generated video. Router re-hosts the video onto Comfy storage and rewrites this field, so it is normally a Comfy-signed URL valid for up to 24 hours - signed for 24 hours when minted and replayed from a 23-hour memo, so a later poll can hand back one with as little as an hour left. When the re-host could not be performed the field keeps xAI’s own short-lived URL instead. NULLABLE: a success whose
url is empty is not a completed generation. Either way the link expires, so download the video rather than storing the URL.Examples
Output
Before you ship
Save oneIdempotency-Key for each call and reuse it for retries. Router can hold the connection for up to 10 minutes. The SDKs handle authentication; raw HTTP clients send the headers themselves.
Use X-Comfy-Error-Type to classify a failure. A 422 means Router rejected the input before calling the provider. Download generated assets promptly because result URLs can expire.
Headers
Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.
Using the Router API
Find models, inspect schemas, and retry safely.
