I'm interested in how backlinks, refpages, and/or traffic changes over time for particular URLs (e.g. news articles or blog posts). Currently the API has backlinks_new_lost_counters and refdomains_new_lost_counters which would be useful, but the results are aggregated by day, so if an article was published 2 years ago, that would be over 700 results which is expensive. It would be useful to have some aggregation by month or at least week.
