Domain authority

POST https://tools.yukai.uk/api/v1/domain-authority

Authority score of one domain. The domain's open-data authority profile: a 0-100 score (web-graph rank and referring domains), the rank by harmonic centrality and PageRank in the Common Crawl web graph of 133 million domains, referring domains and subdomains, the Majestic Million rank with referring subnets and IPs, and the Chrome UX Report popularity bucket. The dataset is quarterly (release in dataset.release). It is an independent open-data measure, not Moz Domain Authority or Ahrefs Domain Rating, and it counts domains, not individual pages.

Cost

Credits: 27 ($0.0027) per successful call. Failed calls are free. Source price: domain-authority/domain-checked.

Input

Send a JSON body (POST) or the same fields as a query string (GET).

Required: domain.

Field	Type	Default	Description
`domain` required	string		A domain or website address: `stripe.com`, `https://www.stripe.com/pricing`, `shop.example.co.uk` (the parent domain is used when the exact name is not in the dataset, unless `exact=true`). Alias: `url`.
`exact`	boolean	`false`	`true`: look up exactly this host (no fallback to the parent domain, e.g. `shop.example.com` does not become `example.com`).
