An SEO data API for the link side of the job
If your tool needs authority and link data for a domain rather than a full SEO suite, this API returns Domain Rating, backlinks, referring domains, anchors and top pages as JSON, billed per call.
Built for one slice of SEO data
SEO APIs usually bundle keywords, rankings, audits and links behind one subscription. This one does only links, which is why it can be priced per call: domain lookups are free and the list endpoints cost 2 credits ($0.0002) per call returning up to 1,000 rows.
Typical uses
Enrich a lead or prospect list with Domain Rating, rank outreach targets by authority, build a competitor link-gap report, show backlink counts inside a client dashboard, or let an AI agent check how well-linked a site is before it cites it. Bulk lookups take up to 2,000 domains per request.
What is not included
Keyword volumes, rank tracking, SERP scraping, traffic estimates and site audits are not part of this API. If you need those, pair it with a provider that does them; the alternatives hub compares the main options.

New accounts get $100 of credit. See the backlink API page and the documentation for every action and parameter.
