puts response.read_bodySnapGen exposes an OpenAI-compatible image generations endpoint. Select the exact model page under Image Series for its price and output rules.
Image generation is synchronous and can take 20 to 60 seconds. Set a client timeout of at least 120 seconds.
On macOS, replace
string
required
An image model ID returned by
GET /v1/models.string
required
A clear description of the image to generate.

Use
1024x1024, 1536x1024, or 1024x1536 for an explicit square,
landscape, or portrait frame. Omit it for automatic framing.integer
default:"1"
Request one image. The current SnapGen image routes do not support batch
generation.
Generate an image
curl https://api.snapgen.org/v1/images/generations \
-H "Authorization: Bearer $SNAPGEN_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-image-2",
"prompt": "A precise indigo product icon on a white background",
"size": "1024x1024",

Decode the response
The response contains base64 image bytes atdata[0].b64_json.
curl https://api.snapgen.org/v1/images/generations \

-d '{"model":"gpt-image-2","prompt":"An indigo paper lantern"}' \
| jq -r '.data[0].b64_json' \
