SEOmoz, a leader in SEO software, has offered link intelligence APIs for a few years (Mozscape being the latest). Although Mozscape has garnered high adoption rates (over 10 million requests/day), customer feedback uncovered shortcomings. SEOmoz now knows that 10 requests/second and a max of 50 URLs/batch "is not able to support everyone's use case." Accordingly, SEOmoz enhanced Mozscape API capabilities and is currently in beta. Although the beta is in its early stages, throughput has increased 400%.
