# CLI reference

> python -m minerva — a help screen + cheat-sheet for users who installed the SDK and aren't sure where to start.

The SDK is primarily a library. The CLI entry point exists so a new user
typing `python -m minerva` gets a useful response rather than silence.

```bash theme={null}
python -m minerva           # banner + cheat-sheet
python -m minerva --help    # argparse help with usage epilog
python -m minerva --version # → minerva-sdk X.Y.Z
```

The cheat-sheet covers:

* Credential resolution (constructor args vs env vars)
* Quick examples for `mc.api.resolve`, `mc.api.enrich`, `mc.api.call`, `mc.usage.tallies`
* The two resource namespaces (`mc.api`, `mc.usage`)
* Where to dig deeper (`help(Minerva)` in REPL)

## Env vars the SDK reads

| Variable          | Purpose                                                                     |
| ----------------- | --------------------------------------------------------------------------- |
| `MINERVA_API_KEY` | Your `x-api-key`. Required if you don't pass `api_key=` to the constructor. |

Just the one. The SDK never reads any other env var.

<Tip>
  For per-method docs, REPL is faster than this docs site —
  `help(mc.api.enrich)` shows the exact signature, args, returns, raises, and
  an example for one method.
