Authority Labs alternative — the apibacklinks backlink API

Authority Labs earned its reputation the hard way. The problem isn't the data; it's getting that data out, cheaply, as JSON. As it describes itself: “… For example, Skratch Labs also has a backlink from a Runner’s … than a backlink from a high-authority but low-relevance site. …”

Dashboards are built for humans clicking around, not for a service that needs a referring-domain list for ten thousand URLs by Tuesday.

apibacklinks was built for exactly this: referring domains, backlinks, anchors and a 0–100 Domain Rating, delivered as JSON over a web-scale link graph. Domain Rating and link counts are free and keyless; the heavy backlink and referring-domain lists cost about a tenth of what Authority Labs and the incumbents charge.

The numbers for authoritylabs.com above come straight from that index — proof it works on the brand you’re comparing. Grab a key, pass ?key=, and you're migrated — with $100 of credit and no monthly minimum waiting on you.
