Code Examples: Implementing Flux Schnell API

SkillBoss provides an OpenAI-compatible API interface, making integration straightforward for developers already familiar with standard AI API patterns.

Python Example

import requests
import json

# SkillBoss API configuration
api_url = "https://api.heybossai.com/v1/chat/completions"
api_key = "your_skillboss_api_key"

# Prepare the request
headers = {
    "Authorization": f"Bearer {api_key}",
    "Content-Type": "application/json"
}

payload = {
    "model": "replicate/black-forest-labs/flux-schnell",
    "messages": [
        {
            "role": "user",
            "content": "A serene mountain landscape at sunset with vibrant orange and purple clouds reflecting on a crystal-clear lake"
        }
    ]
}

# Make the request
response = requests.post(api_url, headers=headers, json=payload)
result = response.json()

# Extract the generated image URL
image_url = result['choices'][0]['message']['content']
print(f"Generated image: {image_url}")

cURL Example

curl https://api.heybossai.com/v1/chat/completions \
  -H "Authorization: Bearer your_skillboss_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "replicate/black-forest-labs/flux-schnell",
    "messages": [
      {
        "role": "user",
        "content": "A futuristic cityscape with flying cars and neon lights, cyberpunk style"
      }
    ]
  }'
