Most tools that want Ahrefs data programmatically want a tiny slice of it: a DR badge in a report, a traffic column in a prospecting sheet, an authority filter in a marketplace. Buying a full seat — plans start around $129/month, with API access positioned above that — to fetch three fields per domain is how "SEO data" quietly becomes a product's biggest line item.
The alternative isn't worse data. It's the same authority metrics, fetched from the Ahrefs API under our subscription, served per credit with provenance on every field — plus the Similarweb-style total-visit estimate Ahrefs doesn't sell, in the same response.
