# Linker Endpoints

## Purpose
Document linker API endpoints for internal linking operations.

## Code Locations (exact paths)
- Routing: `backend/igny8_core/modules/linker/urls.py`
- Views: `backend/igny8_core/modules/linker/views.py`
- Services: `backend/igny8_core/business/linking/services/*`

## High-Level Responsibilities
- Provide linker-related endpoints (as defined in `LinkerViewSet`) for managing internal linking logic.

## Detailed Behavior
- Base path: `/api/v1/linker/`
- Router registers root `LinkerViewSet` (see module code for actions/fields).
- Inherits base viewset scoping, unified responses, permissions, throttling defined in module views.

## Data Structures / Models Involved (no code)
- Linking-related models/services (see business/linking).

## Execution Flow
- Requests → DRF auth → LinkerViewSet → service logic → unified response.

## Cross-Module Interactions
- May consume writer content to generate linking recommendations; interacts with linker services.

## State Transitions
- As defined by LinkerViewSet actions (not detailed in code snippet).

## Error Handling
- Standard unified responses and throttling.

## Tenancy Rules
- Inherits account/site scoping from base classes.

## Billing Rules
- None specified.

## Background Tasks / Schedulers
- None specified in endpoints.

## Key Design Considerations
- Endpoint actions rely on business/linking services; keep scoping intact.

## How Developers Should Work With This Module
- Extend LinkerViewSet/actions as needed; ensure base scoping and unified responses remain consistent.
