Quick start

Call the MOSS-Image API

cURL
STATUS_URL=$(curl --request POST 'https://api.mage.space/v1/moss_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": "moss-image"
}' | 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('moss_image', {
  prompt: 'Editorial portrait in soft daylight, 35mm film look',
  aspect_ratio: '4:5',
  model_id: 'moss-image',
});

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

mage = Mage()  # reads MAGE_API_KEY

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

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