Q: How do I install apimart-image-gen?

Run npx skills add https://github.com/kangarooking/kangarooking-skills --skill apimart-image-gen in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/apimart-image-gen/ (personal) or .claude/skills/apimart-image-gen/ (project).

Generate and download images through APIMart's asynchronous GPT-Image-2 API. Use when Codex needs APIMart image generation, GPT-Image-2 text-to-image, image-to-image with reference URLs or local image files, 1k/2k/4k output, aspect-ratio control, task polling, or saving APIMart image results locally.

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/kangarooking/kangarooking-skills --skill apimart-image-gen

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads apimart-image-gen automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

APIMart Image Gen

Use this skill to submit GPT-Image-2 image jobs to APIMart, poll the async task result, and download returned image URLs.

Credential Rule

Read the API key from an environment variable. Do not hardcode API keys in prompts, scripts, skill files, zip packages, commits, or shell history.

Preferred variable:

export APIMART_API_KEY="..."

The helper also accepts APIMART_TOKEN as a fallback.

Quick Start

Use the bundled helper for normal requests:

python scripts/apimart_image_gen.py generate \
  --prompt "一只橘猫坐在窗台上看夕阳，水彩画风格" \
  --size "16:9" \
  --resolution "2k" \
  --output-dir ./outputs/apimart-image-gen

The script submits POST /v1/images/generations, waits before the first poll, queries GET /v1/tasks/{task_id}, and downloads completed image URLs into --output-dir.

Workflows

Text-to-image:

python scripts/apimart_image_gen.py generate \
  --prompt "a corgi astronaut on the moon, cinematic" \
  --size "16:9" \
  --resolution "2k"

Image-to-image with public URLs:

python scripts/apimart_image_gen.py generate \
  --prompt "把参考图变成水彩画风格" \
  --image-url "https://example.com/photo.jpg" \
  --size "4:3" \
  --resolution "2k"

Image-to-image with local files:

python scripts/apimart_image_gen.py generate \
  --prompt "融合这些参考图，生成一张公众号封面" \
  --image-file ./reference-a.png \
  --image-file ./reference-b.jpg \
  --size "21:9" \
  --resolution "2k"

Check an existing task:

python scripts/apimart_image_gen.py status \
  --task-id task_01KPQ7J7DWB7QZ3WCEK3YVPBRA \
  --download \
  --output-dir ./outputs/apimart-image-gen

Validate request shape without calling the API:

python scripts/apimart_image_gen.py generate \
  --prompt "星空下的古老城堡" \
  --size "16:9" \
  --resolution "4k" \
  --dry-run

Defaults And Limits

Model is fixed to gpt-image-2.
n is fixed to integer 1; do not send "1" as a string.
Valid resolution values are 1k, 2k, and 4k.
Valid ratio values are auto, 1:1, 3:2, 2:3, 4:3, 3:4, 5:4, 4:5, 16:9, 9:16, 2:1, 1:2, 3:1, 1:3, 21:9, and 9:21.
Pixel sizes such as 1881x836 or 887x1774 are also accepted.
Up to 16 reference images can be supplied across --image-url and --image-file.
Prefer putting aspect ratio in --size, not in the prompt, to avoid conflicting instructions.
Result URLs should be downloaded promptly because APIMart reports an expires_at timestamp.

Reference

Read references/api.md when you need endpoint details, status values, error handling, or the size/resolution map.
