GETTING STARTED

Quick Start

Get Keel running in under 5 minutes. Install the SDK, wrap your Anthropic client, and start tracking costs automatically.

1

Install the SDK

Terminal
pip install keel-sdk
2

Wrap your Anthropic client

agent.py
import anthropic
import keel

client = keel.wrap(
    anthropic.Anthropic(api_key="sk-ant-..."),
    agent="my-agent",
    api_url="http://localhost:8000",
    api_key="your-keel-key",
)

# Use exactly like the normal Anthropic client, nothing else changes
response = client.messages.create(
    model="claude-haiku-4-5-20251001",
    max_tokens=100,
    messages=[{"role": "user", "content": "Hello"}],
)

print(response.content[0].text)

Every call automatically captures token usage and cost in a background thread. Your agent is never blocked.
