  description: >-
    REST endpoints for every ADSMCP tool. Same surface as the MCP server, over
    plain HTTP for consumers that can't speak SSE (n8n, Zapier, Make, curl, any
    language's HTTP client).


    ## Envelope

    Every request wraps tool-specific input in an `arguments` object:

    ```json

    { "arguments": { <tool-specific fields> } }

    ```

    Every response wraps the result in either a success envelope (`success:
    true`, `data: {...}`) or an error envelope (`success: false`, `error:
    "..."`, `is_error: true`).


    ## Authentication

    Pass your API key as `Authorization: Bearer sk_live_...` on every request.
    Generate keys at https://adsmcp.si/dashboard/api-tokens.


    ## Quota & billing

    Every successful billable call decrements your monthly tool-call allowance.
    The current counter is attached to every 200 response under `data.quota`:

    ```json

    "quota": { "used": 42, "limit": 150, "tier": "plus", "period_end":
    "2026-05-01" }

    ```

    When the limit is hit, the API returns HTTP 402 with a full `quota` block
    including `upgrade_url`. Read-only diagnostic tools (`get_usage_status`,
    `list_connected_accounts`, `get_connections_status`) are exempt and never
    consume quota.


    ## Idempotency

    Write operations accept an `Idempotency-Key: <uuid>` header. A repeated call
    with the same key returns the cached result rather than executing twice.
    **Strongly recommended for n8n, Zapier, and any retry-prone client** — it
    prevents duplicate campaigns when networks misbehave. Generate a fresh UUID
    per logical operation (not per retry).


    ## Multi-account users

    Customers with multiple connected accounts on the same platform (e.g. an
    agency with 10 Meta ad accounts) must specify which account to use via
    `ad_account_id`, `customer_id`, `advertiser_id`, or `account_id` depending
    on the platform. Omitting it returns HTTP 400 with a list of valid account
    IDs. See `list_connected_accounts` to discover available IDs.


    ## HTTP status codes

    - `200` — success (parse `data`)

    - `400` — tool-level error (surface `error` to users)

    - `401` — bad/missing API key

    - `402` — ADSMCP quota exhausted

    - `404` — unknown tool name

    - `429` — upstream ad platform rate-limited us (Meta/Google/etc.) — retry
    with backoff

    - `500` — server error, report to support


    ## Streaming

    This endpoint is plain request-response JSON. There is **no SSE, no chunked
    streaming**. Safe to use from n8n Cloud's HTTP Request node, Zapier
    Webhooks, Make HTTP module, curl, and every mainstream HTTP library.

      summary: Validate And Prepare LinkedIn Assets
      description: >-
        User provides image URLs to validate BEFORE creating LinkedIn image
        campaign.


        Validate and prepare new image assets for LinkedIn ad campaigns.


        IMPORTANT:

        - Call `get_linkedin_organizations` FIRST to get organization_id AND
        account_id

        - Include `account_id` when calling this tool - it's REQUIRED for images
        to be discoverable later!


        LinkedIn Image Requirements:

        - Horizontal (Sponsored Content): 1200x627 pixels

        - Square (Sponsored Content): 1080x1080 pixels

        - Vertical (Stories/Mobile): 1200x1500 pixels

        - Carousel cards: 1080x1080 pixels (each card)

        - Maximum file size: 8MB

        - Formats: JPEG, PNG, GIF (non-animated)


        Parameters:

        - image_urls: List of public image URLs (e.g., from postimages.org,
        imgbb.com)

        - organization_id: LinkedIn Organization (Company Page) ID

        - account_id: LinkedIn Ad Account ID - REQUIRED for images to be
        discoverable via `discover_linkedin_assets`!

        - ad_type: Target ad type (single_image_horizontal, single_image_square,
        single_image_vertical, carousel)


        Returns:

        - Validation results for each image

        - asset_bundle_id (valid for 60 minutes)

        - Image URNs for reference


        Execution time: 5-15 seconds (downloads, validates, and uploads images)


        Workflow:

        1. Call `get_linkedin_organizations` - get organization_id AND
        account_id

        2. Call `validate_and_prepare_linkedin_assets` with BOTH organization_id
        AND account_id

        3. Use returned `asset_bundle_id` in `create_linkedin_image_campaign`


        Why account_id matters:

        - Without account_id, images are uploaded but NOT associated with your
        ad account

        - This means `discover_linkedin_assets` won't find them later

        - Always include account_id to make images reusable!

            Client-generated UUID to make writes idempotent. Strongly
