Grok Image API

Use this skill to work with image endpoints that expose:

• POST /v1/images/generations
• POST /v1/images/edits

Prefer practical workflows: generate or edit an image, save the result locally, and then send or reuse the saved file.

Quick start

Prefer the bundled script:

• scripts/grok_image_api.py generate for text-to-image
• scripts/grok_image_api.py edit for image editing
• scripts/grok_image_api.py probe to verify the endpoint is reachable

Default environment variables:

• IMAGE_API_BASE_URL
• IMAGE_API_KEY

Workflow

1. Identify the task: generate or edit.
2. Load credentials through environment variables.
3. For generation, send JSON to /v1/images/generations.
4. For editing, send multipart form data to /v1/images/edits with image and optional mask.
5. Save the returned image locally. If the API returns a URL, download it locally by default.
6. If the user is on QQ and wants the image delivered, reply with a \x3Cqqimg> tag pointing to the local file or returned URL.

Generation

Example:

IMAGE_API_BASE_URL="https://example.com/v1" \
IMAGE_API_KEY="..." \
python3 scripts/grok_image_api.py generate \
  --style anime \
  --preset-size portrait \
  --prompt "a cozy cyberpunk tea shop at night" \
  --out /tmp/generated.png

Use --size or --preset-size, --style, --model, --n, and --extra key=value when needed.

Editing

Example:

IMAGE_API_BASE_URL="https://example.com/v1" \
IMAGE_API_KEY="..." \
python3 scripts/grok_image_api.py edit \
  --image /absolute/path/input.png \
  --style cute \
  --prompt "replace the background with a sunset beach" \
  --out /tmp/edited.png

Add --mask /absolute/path/mask.png if the API supports masked edits.

Notes

• Assume this service is not a full chat-completions endpoint.
• Do not call unrelated routes unless the user explicitly says they exist.
• Avoid echoing secrets back to the user.
• Prefer local saved files for messaging channels that can upload local images.
• Default output directory is a local output/grok-images/ folder when --out is omitted.
