Key API changes include: removal of the nber_subcategories endpoint, endpoint renaming from plural to singular, expansion from 7 to 27 endpoints, introduction of API key requirements, nested field structures, renamed fields (patent_number is now patent_id), and a new cursor-based paging system. The R package itself migrated from httr to httr2, removed cast_pv_data(), added a new retrieve_linked_data() function, and includes five new vignettes covering migration and new features. However, the long-term viability of the PatentsView API is uncertain, as the API team has removed the forum and API key request link without official explanation, and the API is funded by USPTO which may be cutting costs. ## Full article daily.dev links to this article rather than hosting it.
