Then click on your avatar on the top right corner, select "My secret keys".

⚠️ The SDK is meant to be run in a safe environment (in a server), not in the browser. The secret should not be shared with anyone. On the other hand, the generative URL you can safely share and place it anywere.

🛠️ SDK Example

import AigenSDK from 'aigen-sdk' //or: const AigenSDK = require('aigen-sdk')

const aigen = new AigenSDK('your-secret-key') //optionally you can set your secret to the AIGEN_SECRET environment variable

// Generate an image from a prompt
const url = await aigen.generateImage('a futuristic cityscape', {
  width: 1024,
  height: 768,
  model: 'gpt-image-1@openai', // using OpenAI's new GPT image generator
  profile: 'facebook:username' // fetch user's Facebook profile image
})

console.log('Generated URL:', url)

// Create an image from a template with variables
const templateUrl = await aigen.createImage({
  template: 'templateId/version',  // Format: templateId/version
  data: {
    name: 'John Doe',
    company: 'Acme Inc',
    role: 'CEO'
  }
})

console.log('Template URL:', templateUrl)

🎨 Advanced Image Manipulation Examples

Here are some advanced image manipulation techniques using the powerful gpt-image-1@openai model:

Make the background of an image transparent

// Using original image reference with a prompt specifying transparency
const url = await aigen.generateImage('Remove the background and make it transparent. Keep the main subject crisp and clear with a perfect alpha mask.', {
  original: 'https://images.pexels.com/photos/1036623/pexels-photo-1036623.jpeg',
  model: 'gpt-image-1@openai'
});

CLI:

npx aigen-sdk generate 'Remove the background and make it transparent. Keep the main subject crisp and clear with a perfect alpha mask.' --original=https://images.pexels.com/photos/1036623/pexels-photo-1036623.jpeg --model=gpt-image-1@openai

Edit an existing image on the internet

// Edit an image from the internet by providing its URL
const url = await aigen.generateImage('Change the color of the car to bright red and add mountains in the background. Maintain the original image quality and lighting.', {
  original: 'https://images.pexels.com/photos/1592384/pexels-photo-1592384.jpeg',
  model: 'gpt-image-1@openai'
});

CLI:

npx aigen-sdk generate 'Change the color of the car to bright red and add mountains in the background. Maintain the original image quality and lighting.' --original=https://images.pexels.com/photos/1592384/pexels-photo-1592384.jpeg --model=gpt-image-1@openai

Join images into new professional images

// Create a composite image by describing how to combine elements
const url = await aigen.generateImage('Create a professional product advertisement by combining the product from the reference image with a clean white background. Add elegant text layout for product name and features. Make it look like a high-end commercial advertisement.', {
  original: 'https://images.pexels.com/photos/2517881/pexels-photo-2517881.jpeg',
  model: 'gpt-image-1@openai'
});

CLI:

npx aigen-sdk generate 'Create a professional product advertisement by combining the product from the reference image with a clean white background. Add elegant text layout for product name and features. Make it look like a high-end commercial advertisement.' --original=https://images.pexels.com/photos/2517881/pexels-photo-2517881.jpeg --model=gpt-image-1@openai

Create translations of existing images

// Translate text in an image to a different language
const url = await aigen.generateImage('Translate all text in this image to Spanish, maintaining the same layout, style, and visual elements. Preserve all graphical components and only replace the text content with accurate Spanish translations.', {
  original: 'https://venngage-wordpress.s3.amazonaws.com/uploads/2021/10/TalentLyft-6-Recruitment-Metrics-Infographic-with-Icons.png',
  model: 'gpt-image-1@openai'
});

CLI:

npx aigen-sdk generate 'Translate all text in this image to Spanish, maintaining the same layout, style, and visual elements. Preserve all graphical components and only replace the text content with accurate Spanish translations.' --original=https://venngage-wordpress.s3.amazonaws.com/uploads/2021/10/TalentLyft-6-Recruitment-Metrics-Infographic-with-Icons.png --model=gpt-image-1@openai

Target an existing image to different markets

// Asian market adaptation
const asianUrl = await aigen.generateImage('Recreate this advertisement with East Asian models that resemble the target audience in China and Japan. Keep the same product placement, overall style, and maintain the brand identity. Ensure cultural nuances are appropriate for an Asian market.', {
  original: 'https://images.pexels.com/photos/1644888/pexels-photo-1644888.jpeg',
  model: 'gpt-image-1@openai'
});

// African market adaptation
const africanUrl = await aigen.generateImage('Recreate this advertisement with African models that resemble the target audience in Nigeria and Kenya. Keep the same product placement, overall style, and maintain the brand identity. Ensure cultural nuances are appropriate for an African market.', {
  original: 'https://images.pexels.com/photos/1644888/pexels-photo-1644888.jpeg',
  model: 'gpt-image-1@openai'
});

// European market adaptation
const europeanUrl = await aigen.generateImage('Recreate this advertisement with European models that resemble the target audience in France and Germany. Keep the same product placement, overall style, and maintain the brand identity. Ensure cultural nuances are appropriate for a European market.', {
  original: 'https://images.pexels.com/photos/1644888/pexels-photo-1644888.jpeg',
  model: 'gpt-image-1@openai'
});

// American market adaptation
const americanUrl = await aigen.generateImage('Recreate this advertisement with North American models that resemble the target audience in the United States. Keep the same product placement, overall style, and maintain the brand identity. Ensure cultural nuances are appropriate for an American market.', {
  original: 'https://images.pexels.com/photos/1644888/pexels-photo-1644888.jpeg',
  model: 'gpt-image-1@openai'
});

CLI example for one market:

npx aigen-sdk generate 'Recreate this advertisement with East Asian models that resemble the target audience in China and Japan. Keep the same product placement, overall style, and maintain the brand identity. Ensure cultural nuances are appropriate for an Asian market.' --original=https://images.pexels.com/photos/1644888/pexels-photo-1644888.jpeg --model=gpt-image-1@openai

🖼️ Template-Based Image Creation

The SDK supports creating images from pre-defined templates with variable data. This is perfect for:

• Creating multiple variations of the same design
• Personalizing images with different names, products, or data
• Automating image creation for marketing campaigns, certificates, or badges

Using Templates in SDK

const aigen = new AigenSDK('your-secret-key')

// Create an image from a template
const url = await aigen.createImage({
  template: 'abc123/2',  // Format: templateId/version (version is optional)
  data: {
    name: 'John Doe',
    title: 'Product Manager',
    company: 'Acme Inc',
    // Add any variables your template uses
  },
  duration: 48  // Optional: signature validity in hours (default: 24)
})

console.log('Template URL:', url)

Using Templates in CLI

# Basic usage
npx aigen-sdk template 'abc123/2' --data.name="John Doe" --data.company="Acme Inc"

# With multiple variables
npx aigen-sdk template 'abc123/2' \
  --data.name="John Doe" \
  --data.title="Product Manager" \
  --data.company="Acme Inc" \
  --data.color="#FF5733"
