Brazilian Chamber of Deputies Open Data

About Brazilian Chamber of Deputies Open Data

Provides open data on the Brazilian Chamber of Deputies (Câmara dos Deputados), covering deputies' parliamentary activity expense records dating back to 2008, legislative proposals (proposições) with metadata such as identifiers, type, year, summary, themes, and tracking status, records of proposal authorship, and information on parliamentary fronts (frentes) and interparliamentary groups (grupos) including their members and leadership history. Data is accessible through a RESTful API as well as bulk downloadable files.

Files are organized by year for expenses, proposals, thematic classification, and proposal authorship, and are available in CSV, XLSX, ODS, JSON, and XML formats, with most datasets updated daily. Records include universal identifiers (URIs) for deputies and Chamber bodies, enabling cross-referencing between datasets such as linking proposals to their authors or parliamentary fronts to their member deputies.

The service is aimed at users who need government transparency data on Brazil's federal legislature, whether querying selected records through the API or downloading complete datasets for local processing and analysis.
