火山引擎图片生成

火山引擎图像生成 - 使用火山引擎方舟API生成图片并下载

Security Scan

The skill claims to generate images via 火山引擎 (VolcEngine) and its code, required env var, and instructions are consistent with that purpose.

Purpose & Capability

Name and description match the code and SKILL.md: the skill calls a VolcEngine Ark image-generation endpoint and only requests one credential (ARK_API_KEY), which is the expected credential for this API.

Instruction Scope

Runtime instructions and the Python script stay within the stated purpose (send prompt to remote image API, download result, save to disk). Minor notes: SKILL.md shows both a CLI usage and an 'exec(open(...).read())' pattern — the latter executes the script in-process and is unnecessary for typical use but not malicious. The skill prints the saved file path (prefixed with MEDIA:), and it will transmit user-provided prompts to the remote API (privacy consideration).

Install Mechanism

No install spec — instruction-only with one Python file. Nothing is downloaded or installed by the skill itself.

Credentials

Only ARK_API_KEY is required and used by the code. The script also allows passing the key via a command-line argument (ARK_API_KEY=...), which is documented in the script. No unrelated secrets or config paths are requested.

Persistence & Privilege

always is false and the skill does not modify other skills or request persistent elevated privileges. It only reads ARK_API_KEY and writes generated images into the current directory.

Assessment

This skill appears to do what it says: it sends your prompt and ARK_API_KEY to VolcEngine's Ark image-generation endpoint and saves the returned image locally. Before installing: 1) Verify you obtained the ARK_API_KEY from VolcEngine's official console and that the endpoint (ark.cn-beijing.volces.com) is the expected vendor endpoint for your region. 2) Use a dedicated API key with limited scope and quota, not a long-lived or broadly privileged key. 3) Be aware that any prompts or data you send will be transmitted to the vendor (do not include secrets or private data in prompts). 4) Prefer running the script directly (python volc_image.py "prompt") rather than using the exec(open(...).read()) pattern. 5) Review network and privacy policies if you run this in a sensitive environment. Otherwise the skill's requirements and behavior are proportionate and consistent with its stated purpose.

技术实现

import os
import requests

# API配置
url = 'https://ark.cn-beijing.volces.com/api/v3/images/generations'
api_key = os.environ.get('ARK_API_KEY')

# 请求数据
data = {
    'model': 'doubao-seedream-5-0-260128',
    'prompt': '<用户提示词>',
    'sequential_image_generation': 'disabled',
    'response_format': 'url',
    'size': '2K',
    'stream': False,
    'watermark': True
}

# 发送请求
response = requests.post(url, headers={
    'Authorization': f'Bearer {api_key}',
    'Content-Type': 'application/json'
}, json=data)

# 获取图片URL并下载
img_url = response.json()['data'][0]['url']
img_data = requests.get(img_url).content

# 保存图片
with open('output.jpg', 'wb') as f:
    f.write(img_data)

注意事项

• API Key 需要在火山引擎控制台获取
• 图片URL有效期约24小时
• 生成图片可能需要几秒钟时间

执行命令

设置API Key并生成图片：

# 设置API Key
set ARK_API_KEY=你的API密钥

# 生成图片
python volc_image.py "你的提示词"

或者在Python中直接调用：

import os
os.environ['ARK_API_KEY'] = '你的API密钥'
exec(open('volc_image.py').read())
