The body is optional — restoring without a word is legitimate, and the default message names the restored `sha`. ## OpenAPI ````yaml /api-reference/openapi.json post /projects/{projectId}/wiki/{pageId}/revisions/{revisionId}/restore openapi: 3.1.0 info: title: Atako API version: 0.1.0 description: >- The Atako customer API — manage AI agents, their files, integrations, billing, and your company/team, programmatically. ## Authentication Every non-public endpoint takes a Bearer token that is either: - a **programmatic API key** (`aik_…`) — create one at [app.atako.ai](https://app.atako.ai) → Settings → API keys (company-admin only), or - a **Supabase session JWT** — what the web app itself sends; not practical to obtain outside a browser session. ```bash curl https://api.atako.ai/agents -H "Authorization: Bearer aik_..." ``` An API key acts as its owning user, with all of that user's permissions — there is no separate key scope in this release. ## Other Atako HTTP surfaces (not covered by this spec) - **Atako MCP server** — `POST /mcp` (auth: same Bearer token as above) exposes a read-only Model Context Protocol tool catalogue for AI clients (Claude Code, Claude Desktop, Cursor, ChatGPT). See [docs.atako.ai/developers/mcp/overview](https://docs.atako.ai/developers/mcp/overview). - **Content API** (`cak_…` key, `/content/*`) — a separate, more restricted key type for headless CMS-style access to blog/news/use-case content. Not documented here. ## Errors Errors use a JSON envelope: `{ "error": string, "code"?: string }`. `error` is either a short human-readable message or a SCREAMING_SNAKE_CASE code, depending on the route — treat it as an opaque string to match against, not a stable enum across the whole API. ## Rate limits Authenticated routes: 6000 requests/min per user (`authRateLimit`). Public GET routes: 60/min per IP. A handful of sensitive public POST routes (newsletter signup, email-exists, invitation preview) are limited to 10 requests / 15 min per IP. ## Pagination List endpoints use either simple `limit`/`offset` query params (marketing content — a plain JSON array response, capped at the documented max) or `page`/`limit` (credit transactions). Neither returns a total count today; fetch until a page comes back shorter than `limit`. servers: - url: https://api.atako.ai description: Production security: [] tags: - name: Agents - name: Messages - name: Activity - name: Agent Options - name: API Keys - name: Files - name: Cron Jobs - name: Sub-Agents - name: Interagent Messages - name: Integrations - name: Subscriptions - name: Users - name: Company - name: Teams - name: Floor - name: Projects - name: Public - name: Marketing Content paths: /projects/{projectId}/wiki/{pageId}/revisions/{revisionId}/restore: post: tags: - Projects summary: Go back to an earlier version of a page description: >- Nothing is erased: restoring ADDS a revision whose content is the old one, so the history of a page never gets shorter.
