keywords.duoleads.com/v1/referring-domains

Domains linking to a domain, strongest first: each referring domain's rank (0-1000), backlinks and linking pages to the target, nofollow and broken links, first seen and spam score, up to 100 rows per $0.048 call, from a web link index. Use when sizing or comparing a site's link sources. No links is an empty answer, which is still charged. Bad input is a free 400; a data source failure is not charged.
