Cua VLM Router

Instead of deploying and managing computer-use vision language models yourself on various cloud providers, Cua VLM Router gives you instant access to all supported models through a single API key. No infrastructure setup, no multiple provider accounts—just one integration for Claude, Gemini, Qwen, and more.

Setup

from computer import Computer
from agent import ComputerAgent

computer = Computer(os_type="linux", provider_type="docker", image="trycua/cua-xfce:latest")
await computer.run()

agent = ComputerAgent(
    model="cua/anthropic/claude-sonnet-4.5",
    tools=[computer]
)

export CUA_API_KEY="your-cua-key"

Get your API key at cua.ai.

Available Models

Benefits

• Single API key for all supported providers
• Cost tracking in every response
• Unified dashboard for usage monitoring
• No vendor lock-in - switch models without changing code

Cost Tracking

Every response includes usage information:

async for result in agent.run(messages):
    print(f"Cost: ${result['usage']['response_cost']:.4f}")
    print(f"Tokens: {result['usage']['total_tokens']}")

HTTP API

Use the router directly via HTTP for integrations outside Python:

Messages

curl -X POST https://inference.cua.ai/v1/messages \
  -H "Authorization: Bearer $CUA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "anthropic/claude-sonnet-4.5",
    "messages": [{"role": "user", "content": "Hello!"}],
    "max_tokens": 100
  }'

Check Balance

curl -H "Authorization: Bearer $CUA_API_KEY" \
     "https://inference.cua.ai/v1/balance"

When to Use

Multi-provider workflows - Access Claude, Gemini, and Qwen from a single integration.

Cost monitoring - Track spending across all providers in one dashboard.

Team environments - Share a single API key with usage limits and monitoring.

Rapid prototyping - Try different models without setting up individual provider accounts.

For direct provider access or custom billing arrangements, use the provider-specific APIs instead. See Vision Language Models for direct provider setup.
