Quick Start

1) Install Dependency

pip install requests

2) Initialize Skill

import os
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

3) Configure Environment Variable API_KEY

Windows PowerShell:

$env:API_KEY="your-api-key"

macOS / Linux (bash/zsh):

export API_KEY="your-api-key"

Usage Examples (Python)

Style Transfer

import os
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

result = skill.invoke(
    'Seedream 4.0',
    {
        'prompt': 'transform this photo into an oil painting in the style of Van Gogh, vibrant colors, visible brushstrokes',
        'image': 'https://example.com/input-image.jpg'
    },
    api_key=api_key
)
print(result)  # Returns task_id when code=0

Artistic Enhancement

import os
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

result = skill.invoke(
    'Nano Banana Pro',
    {
        'prompt': 'enhance this portrait with dramatic cinematic lighting, professional photography quality, shallow depth of field',
        'image': 'https://example.com/portrait.jpg'
    },
    api_key=api_key
)
print(result)

import os
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

result = skill.invoke(
    'Seedream 4.0',
    {
        'prompt': 'convert this landscape into a cyberpunk cityscape at night, neon lights, rain reflections, futuristic atmosphere',
        'image': 'https://example.com/landscape.jpg',
        'ratio': '16:9'
    },
    api_key=api_key
)
print(result)

Image Remixing

import os
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

result = skill.invoke(
    'Nano Banana',
    {
        'prompt': 'reimagine this image as a watercolor painting, soft edges, pastel colors, artistic interpretation',
        'image': 'https://example.com/original.jpg',
        'strength': '0.7'
    },
    api_key=api_key
)
print(result)

Query Task Result

import os
import time
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

task_id = 'your-task-id'

for _ in range(24):
    r = skill.invoke('Task Result', {'task_id': task_id}, api_key=api_key)
    print(r)
    status = (r.get('data') or {}).get('status')
    if status in ('completed', 'failed', 'succeeded'):
        break
    time.sleep(5)

Task Status Reference

• waiting: queued
• processing: running
• completed: completed successfully
• failed: failed

Error Handling

Tips for Better Results

1. Use High-Quality Input: Better source images yield better transformations
2. Be Specific in Prompts: Describe both the transformation and desired outcome
3. Adjust Strength: Use lower strength (0.3-0.5) to preserve more of the original
4. Match Aspect Ratios: Keep output ratio similar to input for best results
