What This Skill Does

The cheapest-image-generation skill empowers OpenClaw users to trigger high-speed, cost-effective image generation using the EvoLink z-image-turbo API. Designed for efficiency, this tool handles the entire lifecycle of an image request: submission, status polling, and local retrieval. By leveraging the z-image-turbo model, users can generate professional-grade visuals at an extremely low cost of approximately $0.0036 per image, making it ideal for high-volume tasks or prototyping.

Installation

To integrate this skill into your environment, use the OpenClaw command-line interface. Run the following command in your terminal: clawhub install openclaw/skills/skills/evolinkai/cheapest-image-generation

Before running the skill, ensure you have an active API key from Evolink.ai. Set this key in your environment variables as EVOLINK_API_KEY to allow the agent to authorize requests seamlessly.

Use Cases

This skill is perfect for scenarios requiring rapid content creation without heavy compute overhead. Content creators can use it for social media post generation, rapid prototyping of UI assets, or generating quick reference sketches during a brainstorm. Because it is highly affordable, it is also a perfect tool for batch-processing assets for large projects or generating varied placeholders for web development.

Example Prompts

1. "Generate image: A futuristic cyberpunk city street under heavy rain, neon lights reflecting on the pavement."
2. "出图：一只正在阅读古籍的赛博朋克风格猫咪，画质精细。"
3. "generate a picture: a minimalist interior design of a modern living room with warm lighting."

Tips & Limitations

• Resolution Control: Always specify the aspect ratio using the supported tags like 16:9 or 9:16 to ensure your output fits your target platform.
• Reproducibility: Use the optional seed parameter if you need to iterate on a specific composition without the AI changing the structure significantly.
• Polling Efficiency: The skill is designed to poll every 10 seconds; be patient as generation can take up to 12 minutes under heavy network load.
• Security: Always rely on the built-in sanitization logic when the skill handles file paths to prevent directory traversal issues. Ensure you are aware that URLs provided by the API are ephemeral and expire after 24 hours, so the auto-download mechanism is critical for persistence.
