# 反向链接历史

**API:** Data API

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

**Tags:** DataForSEO

单个 `target` 在指定日期范围内每一天的反向链接概况，包含 `date_from`、`date_to`，每个时间点一项。若只需要当前概况，请使用 `post_dataforseo_backlinks_summary_live`。若需要更轻量的时间序列，`post_dataforseo_backlinks_timeseries_summary_live` 每个时间点报告的指标更少。该端点不接受 limit 参数，唯一的调节手段就是减少调用次数。
