Source: https://stratadb.org/docs/reference/hub/info

Read the selected StrataHub's V1 capability advertisement.

| | |
|---|---|
| Command | `hub.info` |
| CLI | `strata hub info` |
| Wire type | `hub_info` |
| Python | `db.hub.info(*, hub_url: 'Optional[str]' = None) -> 'Any'` |
| Access | read |
| Commit | no commit |
| Wire status | stable |

Reads `GET /v1/info` from the effective hub URL resolved by the shared Strata resolver.

Status commands return a scalar or compact status payload and do not mutate database state.

## Examples

### Python

```python
db.hub.info().hash_algorithm                # doctest: +SKIP
```

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `hub_url` | `string or null` | no | Explicit hub URL; when absent the 5-layer resolver runs
(flag, `STRATA_HUB_URL`, project config, global config). |

## Returns

`StatusResponse<HubInfo>`

- `data` (`HubInfo`)
- `type` (`string`)

## Errors

Recover by code, never by message.
