# 域名交集

**API:** Data API

**Endpoint:** `POST /v1/beta/dataforseo/backlinks/domain_intersection/live`

**Tags:** DataForSEO

同时链接到多个目标的域名。⚠️ 这里的 `targets` 是**按位置作为键的对象**——`{"1": "a.com", "2": "b.com"}`——而不是批量端点接受的数组。`exclude_targets` 会把站点从对比中移除。每行包含 `domain_intersection` 以及每个目标的 `summary`。用它找出链接了你的竞争对手却没有链接你的站点。页面级对应端点是 `post_dataforseo_backlinks_page_intersection_live`。
