[konard]

Summary

This PR adds comprehensive examples for accessing the unofficial Midjourney API via Legnext in both JavaScript and Python, along with GitHub Actions workflows to run them manually.

Changes Made

JavaScript Example

• ✅ Created examples/javascript/midjourney-example.js with full implementation
  • Generates images using Midjourney via Legnext API
  • Polls for job completion with status tracking
  • Retrieves and displays generated image URLs
• ✅ Updated package.json with node-fetch dependency and midjourney script
• ✅ Updated .env.example with Legnext API credentials
• ✅ Updated README with comprehensive Midjourney example instructions

Python Example

• ✅ Created examples/python/midjourney_example.py with full implementation
  • Generates images using Midjourney via Legnext API
  • Polls for job completion with status tracking
  • Retrieves and displays generated image URLs
• ✅ Updated requirements.txt with requests dependency
• ✅ Updated .env.example with Legnext API credentials
• ✅ Updated README with comprehensive Midjourney example instructions

GitHub Actions Workflows

• ✅ Created .github/workflows/run-javascript-midjourney.yml
  • Manually triggerable via workflow_dispatch
  • Accepts custom prompts as input
  • Uses repository secrets for API keys
• ✅ Created .github/workflows/run-python-midjourney.yml
  • Manually triggerable via workflow_dispatch
  • Accepts custom prompts as input
  • Uses repository secrets for API keys

API Documentation Reference

The implementation is based on the official Legnext API documentation:

• Base URL: https://api.legnext.ai/api
• Image generation endpoint: /v1/diffusion (POST)
• Job status endpoint: /v1/job/{job_id} (GET)
• Authentication: x-api-key header

How to Use

JavaScript Example

cd examples/javascript
npm install
cp .env.example .env
# Edit .env with your Legnext API key
npm run midjourney

Python Example

cd examples/python
pip install -r requirements.txt
cp .env.example .env
# Edit .env with your Legnext API key
python midjourney_example.py

GitHub Actions

Navigate to the Actions tab and run either:

• "Run JavaScript Midjourney Example" workflow
• "Run Python Midjourney Example" workflow

Note: You need to add LEGNEXT_API_KEY to the repository secrets first.

Testing

• ✅ JavaScript syntax validated
• ✅ Python syntax validated
• ✅ Both examples follow the existing code style
• ✅ READMEs updated with clear instructions
• ✅ Environment variable configuration documented
