One API for All Your AI
Route OpenAI, Gemini, Anthropic, and more through a single endpoint. Pool multiple API keys, get automatic failover, and track every token—with zero markup on provider costs.
Everything You Need
Enterprise-grade AI infrastructure without the enterprise complexity
Key Pooling
Add multiple API keys per provider. We rotate through them automatically, spreading load and avoiding rate limits.
Automatic Failover
If one key hits a rate limit or errors, we seamlessly try the next. Your requests succeed even when individual keys fail.
Usage Analytics
Track tokens, costs, and latency across all providers. See exactly where your AI budget is going.
OpenAI Compatible
Same API format you already know. Point your existing code at our endpoint and it just works.
Native Passthrough
Using Gemini's native API? Just change the base URL. No code refactoring needed—we proxy natively.
Secure by Default
Your provider keys are AES-256 encrypted. Gateway keys are hashed. We never see your actual API keys in plaintext.
# Just change the base URL - that's it! from openai import OpenAI client = OpenAI( api_key="cgw_your_gateway_key", base_url="https://api.gateway.candengo.com/v1" ) response = client.chat.completions.create( model="gpt-4o", # or "gemini-2.0-flash", "claude-3-5-sonnet" messages=[{"role": "user", "content": "Hello!"}] )
