### OneKey Gateway Use One Access Key to connect to various commercial APIs. Please visit the [OneKey Gateway Keys](https://www.deepnlp.org/workspace/keys) and read the docs [OneKey MCP Router Doc](https://www.deepnlp.org/doc/onekey_mcp_router) and [OneKey Gateway Doc](https://deepnlp.org/doc/onekey_agent_router). # gemini Skill Use the OneKey Gateway to access tools for this server via a unified access key. ## Quick Start Set your OneKey access key: ```bash export DEEPNLP_ONEKEY_ROUTER_ACCESS=YOUR_API_KEY ``` Common settings: - `unique_id`: `gemini/gemini` - `api_id`: one of the tools listed below ## Tools ### `generate_image_gemini` Generates an image using the Gemini Image API. Supported Models (aliases are internal): The model parameter allows selection between available image generation models. - "gemini-2.5-flash-image" (recommended default for stable, fast response). - "gemini-3-pro-image-preview". - "gemini-3-flash" Aliases for these models are 'nano-banana 2.5' and 'nano-banana 3 Pro' respectively. Please use 'gemini-2.5-flash-image' unless the user specifically requests the Gemini 3 model. Args: model: The image generation model to use (see supported models above). Defaults to "gemini-2.5-flash-image". Supports: 'gemini-3-flash', 'gemini-3-pro-image-preview', 'gemini-2.5-flash-image' prompt: A detailed text description for the image to be generated. image_name: The filename for the output image, can be a relative path. Defaults to "gemini_output_images.png". output_folder: The optional absolute folder path provided by the user where the image will be saved. Do not use default server locations. aspect_ratio: The aspect ratio of the generated image (e.g., '16:9', '1:1', '4:3'). Defaults to '16:9'. image_size: The size/resolution of the generated image (e.g., '1K', '2K', '4K'). Defaults to '1K'. Return: Dict: Result dictionary containing image path, message, and success status. output_result["image_path"]: str output_result["image_url"]: str output_result["message"]: str output_result["success"]: bool Parameters: - `model` (string, optional): - `prompt` (string, optional): - `image_name` (string, optional): - `output_folder` (object, optional): - `aspect_ratio` (string, optional): - `image_size` (string, optional): ### `generate_image_nano_banana` Generate Image With Nano Banana Args: model: The image generation model to use. Defaults to "gemini-2.5-flash-image". Supported Models such as follows Google Gemini Doc, such as 'gemini-3-flash', "gemini-3-pro-image-preview", "gemini-2.5-flash-image", note that nano-banana is the alias name of the Gemini Image Model. Nano banana 3 Pro refers to Gemini 3 pro preview, and Nono Banana 2.5 refers to Gemini 2.5. Unless specified by user to use Gemini 3 model preview, general 'Neno Banana' image models, please use 'gemini-2.5-flash-image' for more stable and fast response. prompt: A detailed text description for the image to be generated. image_name: The filename for the output image, can be a relative path, such as "./new_gemini_image.png", etc. Defaults to "gemini_output_images.png". output_folder: The optional absolute folder path provided by the user where the image will be saved. Do not use default server locations. aspect_ratio: The aspect ratio of the generated image (e.g., '16:9', '1:1', '4:3'), defaults to '16:9'. image_size: The size/resolution of the generated image (e.g., '1K', '2K', '4K'), defaults to '1K'. Return: Dict: output_result is the result dict of MCP returned output_result["image_path"] = full_path: str output_result["message"] = output_message: str output_result["success"] = success: bool Parameters: - `model` (string, optional): - `prompt` (string, optional): - `image_name` (string, optional): - `output_folder` (object, optional): - `aspect_ratio` (string, optional): - `image_size` (string, optional): # Usage ## CLI ### generate_image_gemini ```shell npx onekey agent gemini-nano-banana/gemini-nano-banana generate_image_gemini '{"model": "gemini-2.5-flash-image", "prompt": "sunrise over mountains", "aspect_ratio": "16:9", "image_size": "1K"}' ``` ### generate_image_nano_banana ```shell npx onekey agent gemini-nano-banana/gemini-nano-banana generate_image_nano_banana '{"model": "gemini-2.5-flash-image", "prompt": "robot reading book", "aspect_ratio": "16:9", "image_size": "1K"}' ``` ### generate_image_nano_banana_with_reference ```shell npx onekey agent gemini-nano-banana/gemini-nano-banana generate_image_nano_banana_with_reference '{"model": "gemini-3-pro-image-preview", "prompt": "winter coat style", "images": ["https://avatars.githubusercontent.com/u/242328252"], "aspect_ratio": "1:1"}' ``` ### ocr_extract_text_from_image ```shell npx onekey agent gemini-nano-banana/gemini-nano-banana ocr_extract_text_from_image '{"images": ["https://avatars.githubusercontent.com/u/242328252"], "model": "gemini-3-flash-preview"}' ``` ### list_items_from_image ```shell npx onekey agent gemini-nano-banana/gemini-nano-banana list_items_from_image '{"images": ["https://avatars.githubusercontent.com/u/242328252"], "model": "gemini-3-flash-preview", "output_json": true}' ``` ## Scripts Each tool has a dedicated script in this folder: - `skills/gemini/scripts/generate_image_gemini.py` - `skills/gemini/scripts/generate_image_nano_banana.py` ### Example ```bash python3 scripts/<tool_name>.py --data '{"key": "value"}' ``` ### Related DeepNLP OneKey Gateway Documents [AI Agent Marketplace](https://www.deepnlp.org/store/ai-agent) [Skills Marketplace](https://www.deepnlp.org/store/skills) [AI Agent A2Z Deployment](https://www.deepnlp.org/workspace/deploy) [PH AI Agent A2Z Infra](https://www.producthunt.com/products/ai-agent-a2z) [GitHub AI Agent Marketplace](https://github.com/aiagenta2z/ai-agent-marketplace) ## Dependencies ### CLI Dependency Install onekey-gateway from npm ``` npm install @aiagenta2z/onekey-gateway ``` ### Script Dependency Install the required Python package before running any scripts. ```bash pip install ai-agent-marketplace ``` Alternatively, install dependencies from the requirements file: ```bash pip install -r requirements.txt ``` If the package is already installed, skip installation. ### Agent rule Before executing command lines or running any script in the scripts/ directory, ensure the dependencies are installed.
