Example request
{
"imageUrl": "https://vidmage.ai/assets/images/samples/blue-eyed-woman-sunlight.webp",
"prompt": "The portrait subject slowly turns toward the window as soft light shifts across the face",
"resolution": "720p",
"motion": "low",
"raw": false,
"loop": false
}# Set VIDMAGE_IDEMPOTENCY_KEY to a unique value for this task; preserve it for transport retries.
curl -X POST "https://vidmage.ai/api/v1/midjourney-video-generator/submit" \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Idempotency-Key: ${VIDMAGE_IDEMPOTENCY_KEY}" \
-H "Content-Type: application/json" \
-d '{"imageUrl":"https://vidmage.ai/assets/images/samples/blue-eyed-woman-sunlight.webp","prompt":"The portrait subject slowly turns toward the window as soft light shifts across the face","resolution":"720p","motion":"low","raw":false,"loop":false}'
# -> { "success": true, "taskId": "...", "creditsConsumed": ... }Task results and recovery
URL of the generated video. Read videoUrl from the completed query response. Preserve taskId while the task is running.
curl -X POST "https://vidmage.ai/api/v1/midjourney-video-generator/query" \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "taskId": "TASK_ID_FROM_SUBMIT" }'
# -> { "success": true, "data": { "status": "...", "videoUrl": "https://..." } }Submission and task queries report the available task and usage information. A timeout is not a confirmed failure. Recover the existing task instead of resubmitting.
For face selection and error recovery, follow Task lifecycle. MCP uses the normalized taskId argument in get_task_result, including capabilities whose REST identifier is requestId.
