Krea 允许企业启用零数据保留（Zero Data Retention）。目前公共 API 支持 Krea 2 Medium、Krea 2 Large 和 Krea 2 Medium Turbo。请联系 sales@krea.ai ↗ 以在你的工作区中启用此功能。启用支持后，按如下方式发起请求：
curl -X POST https://api.krea.ai/generate/image/krea/krea-2/medium \
-H "Authorization: Bearer YOUR_API_TOKEN" \
-H "Content-Type: application/json" \
-H "X-Api-Zero-Data-Retention: 1" \
-d '{
"prompt": "a serene mountain landscape at sunset",
"aspect_ratio": "1:1",
"resolution": "1K"
}'
所提供的任何 URL（例如风格参考图像）都必须是 base64 编码的 data URI。使用外部 URL 将会返回 422 — Zero data retention requires external asset inputs to be data URIs.
STYLE_REF_DATA_URI="data:image/png;base64,$(base64 < ./style-reference.png | tr -d '\n')"
curl -X POST https://api.krea.ai/generate/image/krea/krea-2/medium \
-H "Authorization: Bearer YOUR_API_TOKEN" \
-H "Content-Type: application/json" \
-H "X-Api-Zero-Data-Retention: 1" \
-d '{
"prompt": "a serene mountain landscape at sunset",
"aspect_ratio": "1:1",
"resolution": "1K",
"image_style_references": [
{
"url": "'"$STYLE_REF_DATA_URI"'",
"strength": 0.6
}
]
}'
