19 image models, one API key — GPT Image, Seedream, Qwen, WAN, Gemini.
--- ## What Is This? An [OpenClaw](https://github.com/openclaw/openclaw) skill powered by [EvoLink](https://evolink.ai). Install one skill, and your AI agent becomes a full image studio — **19 models** for generation, editing, and inpainting, all through a single API. | Skill | Description | Providers | |-------|-------------|-----------| | **Evolink Image** | Text-to-image, image-to-image, inpainting, instruction-based editing | GPT Image, GPT-4o, Seedream, Qwen, WAN, Gemini | > This is the image-focused view of [evolink-media](https://clawhub.ai/EvoLinkAI/evolink-media). Install the full skill for video and music generation too. 🚀 **[Try All Models Now →](https://evolink.ai/models)** More skills coming soon. --- ## Installation ### Quick Install (Recommended) ```bash openclaw skills add https://github.com/EvoLinkAI/image-generation-skill-for-openclaw ``` Done. The skill is ready for your agent. ### Manual Install ```bash git clone https://github.com/EvoLinkAI/image-generation-skill-for-openclaw.git cd image-generation-skill-for-openclaw openclaw skills add . ``` --- ## Get API Key 1. Sign up at [evolink.ai](https://evolink.ai/signup?utm_source=github[evolink.ai](https://evolink.ai/signup?utm_source=github&utm_medium=readme&utm_campaign=image-generation-skill-for-openclaw)utm_medium=readme[evolink.ai](https://evolink.ai/signup?utm_source=github&utm_medium=readme&utm_campaign=image-generation-skill-for-openclaw)utm_campaign=image-generation-skill-for-openclaw) 2. Go to Dashboard → API Keys 3. Create a new Key 4. Set the environment variable: ```bash export EVOLINK_API_KEY=your_key_here ``` Or just tell your OpenClaw agent: *"Set my EvoLink API key to ..."* — it'll handle the rest. --- ## Image Generation Generate and edit AI images through natural conversation with your OpenClaw agent. ### Capabilities - **Text-to-Image** — Describe what you want, get an image - **Image-to-Image** — Transform existing images with reference - **Inpainting** — Edit specific regions with mask support - **Instruction-based Editing** — Tell the AI what to change in natural language - **Multi-Resolution** — 1024×1024, 1024×1536, 1536×1024, and custom aspect ratios - **Batch Generation** — Generate 1–4 variations in one call - **Aspect Ratios** — 1:1, 16:9, 9:16, 4:3, 3:4, and more ### Usage Examples Just talk to your agent: > "Generate a watercolor painting of a mountain sunset" > "Edit this photo to make it look like a vintage film still" > "Remove the background from this image and replace it with a beach" > "Create 4 variations of a logo design for a coffee shop" The agent will guide you through missing details and handle generation. ### Models (19) #### Top Picks | Model | Best for | Speed | |-------|----------|-------| | `gpt-image-1.5` *(default)* | Latest OpenAI generation | Medium | | `z-image-turbo` | Quick iterations | Ultra-fast | | `doubao-seedream-4.5` | Photorealistic | Medium | | `qwen-image-edit` | Instruction-based editing | Medium | | `gpt-4o-image` [BETA] | Best quality, complex editing | Medium | | `gemini-3-pro-image-preview` | Google generation preview | Medium | #### Stable Models (15) `gpt-image-1.5`, `gpt-image-1`, `gemini-3-pro-image-preview`, `z-image-turbo`, `doubao-seedream-4.5`, `doubao-seedream-4.0`, `doubao-seedream-3.0-t2i`, `doubao-seededit-4.0-i2i`, `doubao-seededit-3.0-i2i`, `qwen-image-edit`, `qwen-image-edit-plus`, `wan2.5-t2i-preview`, `wan2.5-i2i-preview`, `wan2.5-text-to-image`, `wan2.5-image-to-image` #### Beta Models (4) `gpt-image-1.5-lite`, `gpt-4o-image`, `gemini-2.5-flash-image`, `nano-banana-2-lite` ### MCP Tools | Tool | Purpose | |------|---------| | `generate_image` | Create or edit AI images from text or reference images | | `upload_file` | Upload local images for editing/reference workflows | | `delete_file` | Remove uploaded files to free quota | | `list_files` | View uploaded files and check storage quota | | `check_task` | Poll generation progress and get result URLs | | `list_models` | Browse available image models | | `estimate_cost` | Check model pricing | ### Parameters | Parameter | Type | Default | Description | |-----------|------|---------|-------------| | `prompt` | string | — | Image description (required) | | `model` | enum | `gpt-image-1.5` | Model to use | | `size` | enum | `1024x1024` | Output size or aspect ratio | | `n` | integer | `1` | Number of images (1–4) | | `image_urls` | string[] | — | Reference images for i2i (up to 14) | | `mask_url` | string | — | PNG mask for inpainting (`gpt-4o-image` only) | --- ## Setup — MCP Server Bridge For the full tool experience, bridge the MCP server `@evolinkai/evolink-media` ([npm](https://www.npmjs.com/package/@evolinkai/evolink-media)): **Via mcporter:** ```bash mcporter call --stdio "npx -y @evolinkai/evolink-media@latest" list_models ``` **Or add to mcporter config:** ```json { "evolink-media": { "transport": "stdio", "command": "npx", "args": ["-y", "@evolinkai/evolink-media@latest"], "env": { "EVOLINK_API_KEY": "your-key-here" } } } ``` **Direct install (Claude Code):** ```bash claude mcp add evolink-media -e EVOLINK_API_KEY=your-key -- npx -y @evolinkai/evolink-media@latest ``` --- ## File Upload For image editing or reference workflows, upload images first: 1. Call `upload_file` with `file_path`, `base64_data`, or `file_url` → get `file_url` (synchronous) 2. Use that `file_url` as `image_urls` or `mask_url` for `generate_image` **Supported:** Images (JPEG, PNG, GIF, WebP). Max **100MB**. Files expire after **72 hours**. Quota: 100 files (default) / 500 (VIP). --- ## Workflow 1. Upload reference images or masks if needed (via `upload_file`) 2. Call `generate_image` → get `task_id` 3. Poll `check_task` every 3–5s until `completed` 4. Download result URLs (expire in 24h) --- ## Script Reference The skill includes `scripts/evolink-image-gen.sh` for direct command-line usage: ```bash # Text-to-image ./scripts/evolink-image-gen.sh "Watercolor mountain sunset" --quality 1024x1536 # With reference image ./scripts/evolink-image-gen.sh "Make it look vintage" --image "https://example.com/photo.jpg" # Batch generation (4 variations) ./scripts/evolink-image-gen.sh "Coffee shop logo design" --n 4 # Choose a specific model ./scripts/evolink-image-gen.sh "Photorealistic portrait" --model doubao-seedream-4.5 # Quick iteration with turbo ./scripts/evolink-image-gen.sh "Abstract geometric pattern" --model z-image-turbo ``` ### API Reference Full API documentation: [references/api-params.md](references/api-params.md) --- ## File Structure ``` . ├── README.md # English ├── README.zh-CN.md # 简体中文 ├── SKILL.md # OpenClaw skill definition ├── _meta.json # Skill metadata ├── references/ │ └── api-params.md # Full API parameter docs └── scripts/ └── evolink-image-gen.sh # Image generation script ``` --- ## Troubleshooting | Problem | Solution | |---------|----------| | `jq: command not found` | Install jq: `apt install jq` / `brew install jq` | | `curl: command not found` | Install curl: `apt install curl` / `brew install curl` | | `401 Unauthorized` | Check `EVOLINK_API_KEY` at [evolink.ai/dashboard](https://evolink.ai/dashboard) | | `402 Payment Required` | Top up at [evo ```` ## File: README.tr.md upstream: https://github.com/evolinkai/image-generation-skill-for-openclaw/blob/HEAD/README.tr.md Content is not inlined in the catalog.
