Between seat limits, row caps and “contact sales” API tiers, pulling raw link data at scale turns into a procurement project.
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 Copyscape and the incumbents charge.
The numbers for copyscape.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.
