# Get System Configuration

Returns all system-wide configuration key/value pairs (backed by the
`system_config` table).

## Example response

```json example-response
{
  "base_url": "https://books.example.com",
  "opds_base_url": "https://books.example.com/opds",
  "api_base_url": "https://books.example.com/api"
}
```

The key set is admin-defined and intentionally open — the endpoint emits\nwhatever config keys exist in `system_settings`. Treat the shape as a\ndynamic string-keyed map; do not code against a fixed key list.

## Errors

| Status | Body | When |
| ------ | ---- | ---- |
| 500 | `{"error": "failed to fetch system config"}` | unexpected server error |
