# Preview markets to be deleted

**POST** `/openapi/2026-07/markets/preview`

Given a set of countries, preview which existing markets would be fully claimed and therefore automatically deleted. Call this before creating or updating a market so the caller knows which markets will be removed.

## Request

**application/json**

**Body | Example**

**Body (required)**

- `countries` string[] (required)

  Countries to claim, ISO 3166-1 alpha-2 codes in upper case (e.g., US, JP). Because a country may belong to only one market, any other market whose countries are all claimed here will be automatically deleted
- `except_market_id` string

  Market ID to exclude from the check

```json
{
  "countries": [
    "string"
  ],
  "except_market_id": "string"
}
```
