# Quickstart

## 1. Authentication

All Cronozen services authenticate through a single SSO endpoint.

```bash theme={null}
POST https://cronozen.com/api/auth/login
Content-Type: application/json

{
  "email": "user@example.com",
  "password": "your-password"
}
```

**Response:**

```json theme={null}
{
  "token": "eyJhbGciOiJIUzI1NiIs...",
  "actor": {
    "id": "actor_123",
    "role": "ADMIN",
    "centerId": "center_456"
  }
}
```

## 2. Access a Tenant

Use the JWT token to access tenant-scoped resources:

```bash theme={null}
GET https://cronozen.com/api/centers/center_456
Authorization: Bearer eyJhbGciOiJIUzI1NiIs...
```

## 3. Multi-Tenant Context

Every API call is scoped to the authenticated actor's center. Data isolation is enforced at the database level through scoped Prisma models.

```
Actor → Center Membership → Scoped Data Access
```

<Warning>
  Cross-center data access requires explicit `basePrisma` usage and is restricted to authorized operations only.
</Warning>

## 4. Workspace vs Center

| Concept       | Description                                          |
| ------------- | ---------------------------------------------------- |
| **Center**    | A tenant organization (rehab center, pharmacy, etc.) |
| **Workspace** | A personal space for individual actors               |

Instructors have **isolated** workspace and center data. Parents can view data **across** their children's centers.
