# List Cases

> List your team's Zinc support cases, filtered by status, reason or order.

List the support cases on your team's orders, most recently active first. A case counts as active whenever someone posts on it or its status changes.

Filter with `status`, `reason` and `order_id`, or pass `search` to match part of an order ID or case ID. Page through results with `limit` (up to 500) and `offset`. `total` is the number of cases that match the filters, across all pages.

Each entry is a case summary without its messages. Fetch the thread with [Get Case](https://www.zinc.com/docs/v2/api-reference/cases/get-case.md).

## Case Statuses

A case's status says whose move it is.

| Status | Meaning |
| - | - |
| `open` | Waiting on Zinc support |
| `waiting_on_customer` | Zinc replied and is waiting on you |
| `on_hold` | Waiting on the retailer or carrier |
| `closed` | Resolved, by Zinc or by you with [Close Case](https://www.zinc.com/docs/v2/api-reference/cases/close-case.md) |

> [!NOTE]
>
> `closed` isn't final. Replying on a closed case inside the order's case window reopens it. See [Post Case Message](https://www.zinc.com/docs/v2/api-reference/cases/post-case-message.md).

To find the open case on an order, filter by `order_id` and look for the entry whose status isn't `closed`. There's at most one.

    Zinc lets you search, buy, and return items from top online retailers with a
    single API.
  description: >-
    Search, buy, and return items from top online retailers with a single API.
    Supports AI agent ordering via MPP (HTTP 402) — no account required.
    Supported retailers include 1-800-Flowers, Ace Hardware, Amazon, Amazon CA,
    Amazon DE, Amazon FR, Amazon MX, Amazon UK, Barnes & Noble, Best Buy, Chewy,
    Gap, and 18 more. Ships to the US and 6 other countries (CA, DE, FR, GB, IT,
    MX). The listed retailers are the ones Zinc verifies with daily test orders,
    not the limit of what Zinc can buy from: checkout is attempted at most
    online stores, including Shopify-hosted ones. To ask about a specific store
    before ordering, call GET /retailers/check?url=... — it answers whether Zinc
    will attempt that URL.

  x-guidance: >-
    Zinc lets AI agents buy products from online retailers via a single API. Use
    POST /agent/orders to place an order — no Zinc account needed, payment is
    handled via MPP (HTTP 402 flow). Provide a product URL from a supported
    retailer, a shipping address, and max_price in cents. The API charges
    max_price + $1 API fee upfront and refunds the difference on completion. To
    find products first, the /agent/* data endpoints (search, products/search,
    products/offers, products/details) are MPP-paid at $0.01 per call;
    /agent/search returns orderable URLs to feed straight into /agent/orders.
    GET /retailers lists supported retailers for free (no payment or account).
    Authenticated equivalents (orders, products, managed-accounts) require a
    Bearer token (API key prefixed zn_); those orders are paid from a prefunded
    wallet — GET /wallet/me returns the spendable balance and per-order fee, so
    check it before POST /orders to avoid a 402. Orders are strict by default:
    if the gift option can't be applied or any item can't be bought, the whole
    order fails. When the user wants whatever can be shipped, send fulfillment:
    {"gift": "best_effort", "items": "best_effort"} and read
    fulfillment.concessions on the order to see what was relaxed. max_price is
    never relaxed. Docs: https://zinc.com/docs Supported retailers include
