# New & Lost Backlinks Timeseries Summary **API:** Data API **Endpoint:** `POST /v1/beta/dataforseo/backlinks/timeseries_new_lost_summary/live` **Tags:** DataForSEO New and lost backlinks and referring domains for one `target` per period, grouped by `group_range`. This is the derivative of `post_dataforseo_backlinks_timeseries_summary_live`: that one gives the level, this one the change. A flat total hiding heavy churn only shows up here. For the same figures across many targets at once use `post_dataforseo_backlinks_bulk_new_lost_backlinks_live`. This one takes no limit parameter, so the only lever is calling it less often. ### Pricing reference - Metering: Reported response cost. - Reference request estimate: USD 0.0372. - Reference customer multiplier: 1.0.
