notes: >-
  Derived by reading Atera's own support documentation, not from an OpenAPI file.
  Atera states in its API FAQ that the API is driven by OpenAPI 3.0, but the
  interactive reference at https://app.atera.com/apidocs returns 401 with an empty
  body to any unauthenticated client, and no specification is published at a public
  URL, so no securitySchemes could be parsed.
summary:
  types: [apiKey]
  api_key_in: [header]
  oauth2_flows: []
  oauth2: false
  openid_connect: false
  mutual_tls: false
  transport: https-only
schemes:
- name: X-API-KEY
  type: apiKey
  in: header
  parameter_name: X-API-KEY
  description: >-
    Account-scoped API token supplied on every request. Created in the Atera console
    under Admin > Data management > API; the token value is shown once at creation and
    cannot be retrieved afterwards.

  evidence: >-
    Atera's own PowerShell sample sets $headers.Add("X-API-KEY", 'YOUR_API_KEY_HERE')
    and calls https://app.atera.com/api/v3/agents/machine/$ENV:COMPUTERNAME.
token_model:
  multiple_tokens: true
  named: true
  expiration: required
  max_lifetime: 1 year from creation
  ip_restriction:
    supported: true
    modes: [allow-all, specific-ips]
  permissions:
    modes: [full-access, custom-access]
    granularity: per data domain
    actions: [Read, Write, Delete]
    note: >-
      Custom access sets Read/Write/Delete independently for each of the twelve data
      domains. This is a token permission model, not OAuth scopes — there is no
      authorization server, no consent screen and no scope string, so no scopes/
      artifact is emitted.
  rotation: >-
    Tokens carry an operator-chosen expiration date (maximum one year), so rotation is
    enforced by expiry rather than by a documented rotation procedure.
  announced: >-
    Multiple tokens with expiration dates, IP restrictions and permission scopes shipped
    in 2026 (Release Notes: 2026), initially to new accounts only.

access:
  included_in_subscription: true
  available_during_trial: false
  note: >-
    "The API module in Atera is included as part of your subscription at no additional
    cost. However, it's important to note that during the trial period, API access is
    not available." — Atera API FAQ.
gaps:
- No OAuth 2.0 or OpenID Connect authorization server is published.
- No /.well-known/openid-configuration or /.well-known/oauth-authorization-server on
  app.atera.com (probed 2026-08-06 — see well-known/atera-well-known.yml).
- The interactive API reference cannot be read without an authenticated tenant token,
  so the exact per-operation security requirements are not publicly verifiable.
