# List inter-agent messages sent/received by this agent



## OpenAPI

````yaml /api-reference/openapi.json get /agents/{agentId}/agent-messages
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`.

        exactly if you need to branch on error type). Some routes add extra
