The Unified AI API Gateway for 2026
As the AI model ecosystem fragments across dozens of providers, developers need a unified access layer. That's what SkillBoss provides.
What is an AI API Gateway?
An AI API gateway sits between your application and multiple AI providers, offering:
- Single endpoint for all models
- Unified authentication (one API key)
- Standardized format (OpenAI-compatible)
- Smart routing (fallback, load balancing)
- Unified billing (one invoice)
SkillBoss Architecture
Your App → SkillBoss Gateway → OpenAI
→ Anthropic
→ Google
→ Replicate
→ 30+ more providers
Key Features
1. OpenAI-Compatible API
Every model is accessible through the same format:
curl https://api.skillboss.co/v1/chat/completions \
-H "Authorization: Bearer YOUR_KEY" \
-d '{"model": "ANY_MODEL_ID", "messages": [...]}'
2. Automatic Fallback
Configure fallback chains so your app never goes down:
{
"model": "openrouter/anthropic/claude-sonnet-4.6",
"fallback": ["openrouter/openai/gpt-5", "openrouter/google/gemini-3-pro"]
}
3. Cost Optimization
- Compare pricing across 600+ models
- Route to the cheapest model that meets your quality threshold
- Track spending by model, project, and team
4. For AI Agents
SkillBoss is built for AI agents like Claude Code and Cursor:
# Install the skills pack
npx skillboss install
# Your AI agent now has access to 600+ APIs
