Data APIs / SEO metrics
Ahrefs Domain Rating plus organic-search overview and backlink counts from a major SEO index — the domain-level SEO metrics you would otherwise pull from two dashboards, as three endpoints. Live Google results and AI Overviews have their own APIs.
From 1 credit per call · cache hits free · failed calls refunded · no card for the free tier
Every endpoint accepts format=json, markdown, or both. Use the JSON to filter and store; drop the markdown straight into a prompt.

}3 endpoints in this family. Full parameter reference and a try-it console are in the API docs.
/api/v1/seo/authority1 creditThe domain's Ahrefs Domain Rating (0–100). The response includes Ahrefs' license link, which must be preserved when the metric is displayed.
/api/v1/seo/organic1 creditThe domain's organic-search footprint from a major SEO index (US database): number of organic keywords it ranks for, estimated monthly organic visits, traffic cost (what the same traffic would cost in Google Ads, USD/month), and organic rank. A domain the index has never seen fails with empty_result (refunded).
/api/v1/seo/backlinks1 creditBacklink counts from a major SEO index by scope: root domain (the headline number), hostname, and exact URL. A domain the index has never seen reports zeros.
Score 1,000 prospects by DR and organic traffic in one script.
Drop low-authority domains before outreach.
Track DR, organic traffic, and referring domains for your category monthly.
Live Google search results for any query: organic results with titles, URLs and snippets, People Also Ask, related searches — country and language aware. Pay per call, JSON and markdown.
Estimated monthly visits, global rank, top countries, engagement, and top keywords for any domain — the traffic-intelligence data points, as a pay-per-call API with JSON and markdown output.
Domain registration facts from RDAP: creation and expiry dates, registrar, status codes, and nameservers for any domain — JSON and markdown, cached 7 days.
No card required. Run any endpoint from the Playground, then create an API key when you are ready to automate.
