UCDP API

The Uppsala Conflict Data Program (UCDP) API is a fully RESTful HTTP API returning JSON, providing programmatic access to UCDP conflict datasets including georeferenced events (gedevents), armed conflict, dyadic, non-state, one-sided violence, and battle-related deaths datasets. Access requires a free access token obtained from the API maintainer, supplied via the x-ucdp-access-token HTTP header, with a quota of 5,000 requests per day.
