Quick start

Call the Z-Image API

Set MAGE_API_KEY, submit to /z_image/generate, and poll status_url until the request completes.

cURL
STATUS_URL=$(curl --request POST 'https://api.mage.space/v1/z_image/generate' \
  --header "Authorization: Bearer $MAGE_API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{
  "prompt": "Editorial portrait in soft daylight, 35mm film look",
  "aspect_ratio": "4:5",
  "model_id": "z-image-turbo"
}' | jq -r '.status_url')

# Repeat until status is "completed"; result.url is the file
curl "$STATUS_URL" --header "Authorization: Bearer $MAGE_API_KEY"
TypeScript
// npm install @mage-space/sdk
import Mage from '@mage-space/sdk';

const mage = new Mage(); // reads MAGE_API_KEY

const request = await mage.run('z_image', {
  prompt: 'Editorial portrait in soft daylight, 35mm film look',
  aspect_ratio: '4:5',
  model_id: 'z-image-turbo',
});

console.log(request.result.url);
Python
# pip install mage-space
from mage_space import Mage

mage = Mage()  # reads MAGE_API_KEY

request = mage.run("z_image", {
    "prompt": "Editorial portrait in soft daylight, 35mm film look",
    "aspect_ratio": "4:5",
    "model_id": "z-image-turbo",
})

print(request["result"]["url"])

FAQ

Frequently asked questions

How much does the Z-Image API cost?
A Z-Image request at the default settings (Z-Image) costs 10 Gems, about $0.01. Other resolutions, durations, and variants change the price; the response reports the exact charge. A generation that fails is refunded; one Mage's content policy blocks is not.
What is the Z-Image API endpoint?
POST https://api.mage.space/v1/z_image/generate with an Authorization: Bearer header carrying your Mage API key. The response includes a status_url to poll for the result.
Which Z-Image models can I call?
z-image-turbo (Z-Image). The default is Z-Image.
Does Z-Image support reference images or characters?
Z-Image takes no image, video, or audio inputs. Z-Image takes no @handle mentions.
Can I use Z-Image from Claude or ChatGPT?
Yes. Connect the Mage MCP server to Claude, ChatGPT, Claude Code, Grok, or Cursor and ask for Z-Image by name. Your assistant reads its options with get_model and quotes the price before it generates.
How long are Z-Image results kept?
Results and inputs are kept for 30 days. Download anything you want to keep to your own storage.
