```bash
# Basic usage
headroom proxy

# Deliberate public access, with the existing token protocol
HEADROOM_PROXY_TOKEN='replace-with-a-secret' headroom proxy --host 0.0.0.0 --port 8080
# Send `Authorization: Bearer replace-with-a-secret` or
# `X-Headroom-Proxy-Token: replace-with-a-secret` from the caller.

# With logging and budget
headroom proxy \
  --log-file /var/log/headroom.jsonl \
  --budget 100.0
```

from headroom.integrations.agno import HeadroomAgnoModel

model = HeadroomAgnoModel(wrapped_model=OpenAIChat(id="gpt-4o"))
agent = Agent(model=model)

response = agent.run("What's the capital of France?")

print(f"Tokens saved: {model.total_tokens_saved}")
print(model.get_savings_summary())
# {'total_requests': 1, 'total_tokens_saved': 245, 'average_savings_percent': 12.3,
#  'total_tokens_before': 1990, 'total_tokens_after': 1745}
```

### Set Vertex AI environment variables and start proxy

Source: https://docs.headroomlabs.ai/docs/proxy

Sets the LiteLLM-specific environment variables required by the Vertex AI backend. VERTEXAI_PROJECT and VERTEXAI_LOCATION are not the standard Google Cloud variables; if VERTEXAI_PROJECT is unset, requests may silently bill a different GCP project.

```bash
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json  # or use ADC
export VERTEXAI_PROJECT=<your-gcp-project>
export VERTEXAI_LOCATION=us-central1

headroom proxy --backend vertex_ai --region us-central1
```
