# Account Endpoints

## Purpose
Document account management endpoints for settings, team management, and usage analytics.

## Code Locations (exact paths)
- Routing: `backend/igny8_core/api/urls.py`
- Views: `backend/igny8_core/api/account_views.py`
- Settings/tenancy middleware: `backend/igny8_core/auth/middleware.py`

## High-Level Responsibilities
- Provide account settings retrieval/update, team member management, and usage analytics summaries for the authenticated account.

## Detailed Behavior
- Base path: `/api/v1/account/`
- Settings:
  - `GET /api/v1/account/settings/` → returns account settings (ViewSet `retrieve`).
  - `PATCH /api/v1/account/settings/` → partial update of account settings.
- Team:
  - `GET /api/v1/account/team/` → list team members.
  - `POST /api/v1/account/team/` → create/add a team member.
  - `DELETE /api/v1/account/team/<id>/` → remove a team member.
- Usage analytics:
  - `GET /api/v1/account/usage/analytics/` → returns usage analytics overview (implementation in `UsageAnalyticsViewSet.overview`).
- Permissions/tenancy: views expect authenticated users; account context from middleware; data scoped to `request.account`.

## Data Structures / Models Involved (no code)
- Account, User, and related analytics data as computed in account views.

## Execution Flow
- Requests hit `account_views` ViewSets; account context derived from session/JWT via middleware; view methods return unified responses.

## Cross-Module Interactions
- Usage analytics may summarize module usage (planner/writer/etc.) depending on `UsageAnalyticsViewSet` implementation.

## State Transitions
- Account settings updates; team membership changes.

## Error Handling
- Standard unified responses for validation/auth errors; 404 when deleting non-existent team members.

## Tenancy Rules
- All endpoints scoped to authenticated user’s account; no cross-tenant access.

## Billing Rules
- None directly; account limits and credits are exposed via billing endpoints.

## Background Tasks / Schedulers
- None.

## Key Design Considerations
- Non-router endpoints used for simplicity; still leverage DRF ViewSet actions.

## How Developers Should Work With This Module
- Keep settings/team/usage endpoints under `/api/v1/account/`; ensure account context is required for all operations.
