On this page, the Bureau of Justice Statistics (BJS) will provide criminal justice information in Application Programming Interface (API) format. This information-centric approach is described in further detail in the Federal Digital Strategy and Open Data Policy.
The APIs are free of charge, do not require registration, and allow unlimited access. Please read the terms of service for using the APIs.
To get started, select an API from the list below. The APIs support REST formatted requests and provide researchers and developers with end-points
in XML, JSON, and CSV formats along with related codebooks, methodology, and metadata.
As other criminal justice datasets are made available in API format, they will be added to the list below.
Contact us via AskBJS@usdoj.gov with any comments you have, or to let us know how you are using this new resource.
The NCVS (National Crime Victimization Survey) RESTful API is a web service that provides criminal victimization data obtained annually from a nationally representative sample of about 90,000 households and 160,000 persons interviewed each year.
