Feminizidmap Public API v1.0

Introduction

Feminizidmap documents all femi(ni)cides and killings of women* and girls* in Germany. Femi(ni)cide applies to killings of women* and girls* that occur in the context of hierarchical power relationships — it is not simply a label for homicides by the sex of the victim, but a recognition of the structural subordination that makes these killings possible.

This REST API publishes all public cases from the feminizidmap research database. Each case record contains structured data about the crime, the victim, and the perpetrator. The interface is public and free to use. All responses are JSON.

On this page you will find a description of the available endpoints and their usage as well as a detailed description of the output schema.

Data note: This API exposes data from an actively maintained research database. Fields will be null when information is not yet available.
