Between seat limits, row caps and “contact sales” API tiers, pulling raw link data at scale turns into a procurement project.
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 Quorum21 and the incumbents charge.
The numbers for upsportbet.top 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.
