Domain Authority

GET /v1/domain/authority1 credit / requestcache 1440 min

How authoritative a domain is on the open web, from the Common Crawl domain-level web graph (over 100 million domains and about 2 billion links between them, refreshed with each graph release): a 0-100 Gridlode Authority score and its percentile, harmonic-centrality and PageRank rank and value, the number of referring domains (domains linking to it) and of domains it links to, and the graph release used. The score is round(100 - 12.5 x log10(harmonic-centrality rank)): 100 for rank 1, 75 for rank 100, 50 for rank 10,000, 25 for rank 1,000,000. Subdomains resolve to their registrable domain. Domains that are not in the graph are free.
