Up to 32,000 characters.

Estimate only; nothing is sent. Includes text and one output image.

Use the Images API

Set MINIROUTER_API_KEY to your inference key. Copy the example.

curl --fail-with-body --retry 0 --max-time 120 \
  'https://api.minirouter.sh/v1/images/generations' \
  -H "Authorization: Bearer $MINIROUTER_API_KEY" \
  -D response.headers --output response.json \
  -H 'Content-Type: application/json' \
  --data '{
  "model": "openai/gpt-image-1-mini",
  "prompt": "A blue circle on a white background.",
  "size": "1024x1024",
  "quality": "low",
  "output_format": "png",
  "n": 1
}'

Keep the request ID. The image response can arrive before its final charge. Check Request logs for the settled cost. A failed or disconnected request may still incur a cost; these examples disable automatic retries.
