znajo.pl alternative — the apibacklinks backlink API

znajo.pl earned its reputation the hard way. The problem isn't the data; it's getting that data out, cheaply, as JSON. znajo.pl - polski darmowy backlink checker - linki zwrotne

The data you want — referring domains, backlinks, anchor text, a Domain Rating — is right there, just locked behind an export button and a price.

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 znajo.pl and the incumbents charge.

The numbers for znajo.pl 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.
