  description: "# Backlinks API\n\nThis collection of requests allows you to conduct a comprehensive analysis of the backlink profile for any given target, whether it's a root domain, a specific host (subdomain), or a particular URL.\n\nYou can use these endpoints to retrieve high-level statistics, fetch detailed backlink lists, analyze historical trends, and check authority scores.\n\n### Summary & Core Metrics\n\nUse these endpoints to get a quick overview of a target's backlink profile. These requests support batching for up to 100 targets.\n\n- **`summary`**: Returns extended statistics, including the number of referring domains, IPs, top anchors, TLDs, and more.\n    \n- **`metrics`**: Retrieves a set of key metrics, such as the total number of backlinks, referring domains, and dofollow/nofollow link counts.\n    \n- **`count`**: Provides a simple count of the total number of live backlinks for a target.\n    \n\n### Detailed Backlink Retrieval\n\nUse these endpoints to get lists of the actual backlinks pointing to a target.\n\n- **`all`**: Fetches a detailed list of backlinks with powerful filtering and sorting options. This is ideal for getting the \"top\" backlinks based on criteria like InLink Rank.\n    \n- **`raw`**: Retrieves a complete, unfiltered list of all backlinks using efficient cursor-based pagination. This is best for fetching an entire dataset in batches.\n    \n- **`export`**: Exports all backlinks for a target into a downloadable `.csv.gz` file. This process is asynchronous and designed for very large-scale data retrieval.\n    \n\n### Historical Data & Trends\n\nTrack changes in a backlink profile over time.\n\n- **`history`**: Get a list of new and lost backlinks within a specified date range.\n    \n- **`history/count`**: Returns the number of new or lost backlinks for each day in a given period.\n    \n- **`history/cumulative`**: Provides the total number of live backlinks for each day in a given period.\n    \n\n### Analyze Specific Backlink Aspects\n\nDive deeper into specific components of the backlink profile.\n\n- **`anchors`**: Returns information about the anchor texts used in links pointing to a target.\n    \n- **`refdomains`**: Provides details on the unique referring domains, including their authority and the number of links from each.\n    \n- **`referring-ips`** **&** **`subnets`**: Analyzes the network distribution of backlinks by IP address and C-class subnets.\n    \n- **`indexed-pages`**: Lists the pages on the target site that have received one or more backlinks.\n    \n\n### Authority Scores\n\nCheck the calculated authority of a target based on its backlink profile.\n\n- **`authority`**: Retrieves both the InLink Rank (Page Authority) and Domain InLink Rank (Domain Authority).\n    \n- **`authority/domain`**: Focuses specifically on Domain Authority, including its distribution and historical values.\n    \n- **`authority/page`**: Focuses specifically on Page Authority and its historical values."
