Domain SEO Tools API

Live SEO tools for domain specialists — the same checkers as in the Karma.Domains app. Refresh Ahrefs DR, Moz DA, Semrush, backlinks, spam score, traffic, domain age, DNS, and registration data for one domain per run.

This is not a catalog search and not a WHOIS-only Actor. It is a toolbox: pick a tool, pass a domain, get fresh metrics before you bid or after you shortlist names from Expired Domains API.

Product: karma.domains · Expired Domains API

Why this Actor

SEO workflows need live numbers, not only the snapshot on an expired-domain row:

• Domain Authority checker — Ahrefs Domain Rating (DR), Moz DA, Semrush, Karma Metric (domain_authority).
• Backlink checker — Moz backlinks, referring domains, anchor text, Moz Spam Score.
• Traffic checker — SimilarWeb and Semrush (traffic).
• Domain age — Wayback first/last snapshots and Karma Metric from archive history.
• DNS lookup — Google, Cloudflare, OpenDNS, Quad9.
• Registration tools — availability, WHOIS/RDAP, created/expiry dates (when you need them).
• Sitemap page count — unique URLs from the sitemap.

One origin call per run. You pay Apify pricing on this listing.

Inventory search (9M+ expired / auction names, 90+ filters) is Expired Domains API.
