Indexsy alternative — the apibacklinks backlink API
A developer-first, 10× cheaper Indexsy alternative: backlinks, referring domains, anchors and Domain Rating as one JSON API. $100 free, DR & counts keyless.
Picture your product calling Indexsy for every domain it touches. Now picture the invoice. That's why this page exists. Indexsy - We Build, Acquire & Scale Digital Assets
Dashboards are built for humans clicking around, not for a service that needs a referring-domain list for ten thousand URLs by Tuesday.
apibacklinks hands you the same signals as one authenticated GET, returning clean JSON from our own crawl of the public web: 2.7 billion links across 181 million domains. Domain Rating and link counts are free and keyless; the heavy backlink and referring-domain lists cost about a tenth of what Indexsy and the incumbents charge.
The numbers for indexsy.com above come straight from that index — proof it works on the brand you’re comparing. Point your integration at the endpoint below, keep your $100 of starter credit, and bill only for the calls you actually make.
