The Oregon Legislature freely provides the legislative measure, committee, and legislative member data used in the Oregon Legislative Information System (OLIS) to the public in an Open Data ​Protocol (OData) API. Oregon's Legislative OData API provides complete and up-to-date session information.  OData is an open protocol that allows the creation and consumption of queryable and interoperable RESTful APIs in a simple and standard way.  The legislature's data model outlining exactly what data is available can be found here.
