Image generation
Nano Banana, GPT Image, FLUX.2, Seedream and MAI-Image from the same balance.
Steps
01
Check the model list
GET /v1/models lists chat; see /models for the image catalogue.
02
Send a prompt
POST /v1/images/generations with model and prompt.
03
Collect the URL
Ask for response_format url and download it.
bash
curl https://api.luxechain.si/v1/images/generations \
-H "Authorization: Bearer lxc_live_YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "flux-2-klein",
"prompt": "a red cube on a white table, product photo",
"resolution": "1K",
"aspect_ratio": "1:1",
"response_format": "url"
}'
Image calls are charged per image, not per token. Generation is synchronous and can take up to a few minutes on the larger models, use a client timeout of at least 600 seconds.
