# Apps

Accessor: `sdk.apps`

Create developer apps, fetch app secrets, update app metadata, and publish apps.

## Method surface

| Method                    | Purpose      |
| ------------------------- | ------------ |
| `sdk.apps.getApps()`      | getApps      |
| `sdk.apps.createApp()`    | createApp    |
| `sdk.apps.getAppSecret()` | getAppSecret |
| `sdk.apps.getApp()`       | getApp       |
| `sdk.apps.updateApp()`    | updateApp    |
| `sdk.apps.publishApp()`   | publishApp   |

## Basic usage

```typescript
import NeucronSDK from '@timechainlabs/neucron-ts-sdk';

const sdk = new NeucronSDK({ authToken: process.env.NEUCRON_TOKEN });

// Use sdk.apps methods after authentication.
```

## Notes

* Methods return `Promise<HttpResponse<T>>` unless they are local helpers such as token getters/setters.
* Authenticate with `sdk.auth.login()` or initialize with `authToken` before protected calls.
* Pass `businessId` on business-scoped operations; constructor-level `businessId` is typed but not applied globally.
* Request and response schemas are exported from `@timechainlabs/neucron-ts-sdk` and `@timechainlabs/neucron-ts-sdk/schemas`.
