  "description": "Finds domains that link to one or more competitor targets but NOT to the excluded target (you). The output is a ready-made link-building prospect list; chain it with an email-finder tool to turn rows into outreach. Response shape: each row's referring domain lives at items[].domain_intersection[\"1\"], [\"2\"], ... keyed by the 1-based index of your `targets` array, with that referring domain's own authority score in `rank` (0-1000ish, higher is stronger; this is the referring domain's rank, a different metric from the target-domain rank in backlinks_summary). Default sort is rank descending. When ranking prospects, check referring_domains and backlinks together — a huge backlink count with few referring domains usually means sitewide boilerplate links, not authority.",
