Transparency International Russia's Declarator project has opened its API. Now Declarator data is accessible to anyone interested for any purpose in the special json format, which is compatible with the international popolo standard. They can be downloaded as a single 'dump' (generated every night), or the database can be accessed via the API with integrated search functions.
Declarator's API helps bolster public oversight of elected officials' behavior, and improve investigative reporting and research on the bureaucracy in Russia and other topics.
