# List pages

> Lists the pages you may see, newest first, with each one's title, revision, Session, share state and hero preview. With `reason_id`, the Reason's Library (what its Sessions made, for everyone who has it); with `session_id`, that Session's pages; with neither, every page you may see in the workspace. Cursor-paginated: pass `next_cursor` as `cursor`. Requires pages:read. An Experiments feature (pages_api): elsewhere it returns 403 `pages_api_unavailable`.

  title: Reason API
  version: 3.0.0
  description: >-
    The Reason HTTP API. Drive cloud software-engineering agents: open sessions
    against your repositories, stream their work, and manage the secrets,
    skills, and automations they run with.


    Authenticate with a Reason API key sent as a bearer token. New keys use
    `reason_`; legacy `ara_` keys remain accepted. Every resource is scoped to
    an organization; resolve your `org_id` once with `GET /v3/self`.

  - name: Reasons
    description: >-
      Start here. A Reason is the long-running agent a person keeps: their main
      Reason and named ones, each with its own instructions, default model and
      repositories, conversation, Loops and Sessions. Give a Reason work by
      messaging it (sendReasonMessage) and read its replies with
      listReasonMessages.
  - name: Loops
    description: >-
      Standing work a Reason does, woken by a schedule or an event: a webhook, a
      GitHub event or a Slack message. Each wake opens or continues a Session of
      the Reason; webhook events that share a correlation key continue one
      Session.
  - name: Memory
    description: >-
      What Reasons remember across Sessions. Each Session starts by reading
      MEMORY.md (a short index) and the list of topic notes, and reads a note
      when its topic comes up. `personal` memory belongs to one person (the API
      key's owner) and only their Sessions read it; `team` memory belongs to the
      Workspace and every member's Sessions read it. memory:read lists, reads
      and searches; memory:write writes and deletes, in team memory only for a
      Workspace owner or admin.
  - name: Sessions
    description: >-
      A Session is one run of work inside a Reason: every Reason message and
      Loop wake runs in one, and createSession starts one directly for a single
      unattended task with a pass/fail outcome. Its transcript, events, result
      and pull request are read here.
  - name: Skills
    description: >-
      Reusable instruction bundles Reason selects semantically from their
      descriptions for matching agent tasks.
  - name: Pages
    description: >-
      The HTML pages Reasons make: charts, dashboards and reports a person reads
      in the chat, opens full size, shares and finds in a Reason's Library. List
      and read the pages you may see, make one in a Reason's conversation or a
      Session, keep it current with updatePage (same id, link and share link, a
      new revision), share it and delete it. pages:read reads; pages:write
      writes. An Experiments feature (pages_api): elsewhere these return 403
      `pages_api_unavailable`.
  - name: Secrets
    description: >-
      Encrypted credentials injected into the agent's sandbox. Write-only:
      values can be set but never read back.

      Sessions concurrently.

      Deprecated: a project is a Reason with the same id. Use the Reasons

  - name: Automations
    description: >-
      The older form of Loops. Prefer the Loops under a Reason (listReasonLoops,
      createReasonLoop), which take every wake: schedule, webhook, GitHub,
      Slack. Use these for what Loops do not carry yet: a run's MCP and app
      tools, and automations not filed under a Reason.

        devices:write, devices:use, computers:read, computers:write, ssh:write,
        network:read and network:write are opt-in, excluded from default keys.
        computers:read lists visible cloud and connected computers without
        waking them or granting execution access. devices:read discovers local
        Device targets; devices:use separately consents to local execution, so a
        discover-and-run local workflow needs both. devices:write manages
        enrollment and device grants; computers:write creates or deletes cloud
        computers; ssh:write manages retained SSH access. network:read reads the
        saved workspace network policy; network:write replaces custom allowed
        hosts and requires a current organization owner/admin. Legacy project
        PATCH requests containing network_allowed_hosts also require
        network:write plus their existing run scope and project management
        permission; saved project hosts do not affect current session egress.
        Only owners/admins can mint or manage keys with network:write; keys
        cannot grant themselves more authority. See /docs/network-policies for
        replacement semantics and runtime applicability. mcp:write manages MCP
        server configuration only; it does not authorize remote MCP-tool
        execution. sessions:read reads sessions, including the assistant,
        reasoning and tool activity in their events. sessions:debug is
        privileged: only for organization owners/admins, it expands session
        events to the full diagnostic projection (diagnostic event kinds, status
        text and raw event metadata).
