Based on user feedback, we've released a set of tweaks to ROR's affiliation matching service focused on improving precision and reducing false positive results. The updated affiliation matching service is now available in production, at the existing affiliation matching endpoint https://api.ror.org/organziations?affiliation=. While the search behavior has changed slightly, request and response format remains remains unchanged. Many thanks to ROR integrators who helped to beta test these improvements!
