This document describes the API its own web application uses. **This is an internal application API.** It is not a stable public API: paths, fields and behaviour can change with any release, there is no versioning, and browser requests are tied to the application's own origin. Scoped service credentials exist for the community's own integrations. All paths are relative to `/api` on the deployment's origin. Responses are JSON, never cacheable, and carry an `X-Request-Id` header. servers: - url: http://localhost:3000/api description: Local development - url: '{origin}/api' description: A deployment. `origin` is that deployment's `APP_URL`. variables: origin: default: https://argus.example.org description: The application's public origin, with no trailing slash. security: [] tags: - name: Authentication description: >- Discord sign-in, Roblox account linking, the current user, and temporary Developer Access. - name: CAD Incidents description: >- Control's incidents: creation, editing, closure, and dispatching units to them. - name: CAD Units description: Control's view of operational units and their crew. - name: CAD Calls description: Incoming calls and how they become, or join, incidents. - name: CAD Events description: The append-only operational history. - name: MDT description: >- Self-service for the people crewing a unit: booking on and off, joining a unit, and changing its status. - name: Civilians description: 'The civilian portal: a member''s own characters, licences and vehicles.' - name: PNC Lookup description: >- Searching people and vehicles, full records, record history and official vehicle status. - name: PNC Licences description: Official changes to driving licences. - name: PNC Records description: Official records attached to people. - name: PNC Warrants description: Warrants and their lifecycle. - name: PNC Markers description: Markers and BOLOs on people and vehicles. - name: Staff description: Staff profiles and role membership. - name: Shifts description: Staff shifts. - name: Sessions description: Operational roleplay sessions. - name: Moderation description: Warnings, kicks and bans, with their delivery state. - name: Audit description: The append-only audit log. - name: Administration description: Accounts, roles and service credentials. - name: ERLC x-displayName: ER:LC description: Live data from the ER:LC private server. paths: /pnc/licences/{id}/endorsements/{endorsementId}/remove: post: tags: - PNC Licences summary: Remove an endorsement description: >- **Permission:** `pnc.licences.manage`.
