## 🚀 Quick start

```bash
pip install agentcanvas
```

Set `LOGFIRE_READ_TOKEN` in your environment (or a `.env` file), then build the
report from your latest agent run:

```bash
agentcanvas                       # latest run → agent_flow.html (opens in browser)
agentcanvas --list                # list recent runs
agentcanvas --trace-id <id>       # a specific run
agentcanvas -o report.html --no-open
```

Or use it as a library:

```python
from agentcanvas import LogfireClient, parse_run, render_html

client = LogfireClient()                       # reads LOGFIRE_READ_TOKEN
trace_id = client.latest_trace_id()
report = parse_run(client.fetch_trace(trace_id), trace_id)
open("report.html", "w").write(render_html(report))
```

| Variable | Used for |
|----------|----------|
| `LOGFIRE_READ_TOKEN` | reading traces via the Logfire Query API (required) |
| `LOGFIRE_BASE_URL` | optional region override (default US; EU: `https://logfire-eu.pydantic.dev`) |
| `LOGFIRE_WRITE_TOKEN` | the example agent sending telemetry to Logfire |
| `OPENROUTER_API_KEY` | the example agent (model via OpenRouter) |
