Request example
curl --request POST 'https://aihub-admin.aimix.pro/api-platform/v1/generations' \
-H "Authorization: Bearer $PIXMIND_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "grok-imagine-2-eco",
"prompt": "A polished campaign image with clean composition and controlled lighting",
"resolution": "quality",
"aspectRatio": "1:1"
}'// Node.js 20+. Keep the API key on your server.
const apiKey = process.env.PIXMIND_API_KEY;
if (!apiKey) throw new Error("PIXMIND_API_KEY is required");

method: "POST",

Generation is asynchronous. Save taskId and poll GET /api-platform/v1/tasks/{taskId} until status is ready or failed.
{
"code": 1000,
"data": {
"id": "img_44160",
"taskId": 44160,
"type": "image",
"model": "grok-imagine-2-eco",
"status": "processing"
}
}Query the task and retrieve results
Replace 44160 with data.taskId from the accepted response, using a key belonging to the same user. pending and processing are non-terminal; ready and failed are terminal. On ready, read images (images) or videoUrl (videos); on failed, read errorMessage. The example stops after 60 queries. If it times out, save taskId and query again later instead of creating a duplicate task. Example result URLs are placeholders.
curl 'https://aihub-admin.aimix.pro/api-platform/v1/tasks/44160' \
-H "Authorization: Bearer $PIXMIND_API_KEY"// Continue after the request example above.
