Joshua Project

Verified Jul 2026

Joshua Project is a non-profit research initiative tracking every people group in the world by ethnicity, language, and religious affiliation, with an emphasis on those least reached by Christian missions. Its REST API exposes that demographic and religious-adherence data as free, keyed JSON or XML; a live keyless request to the real v1 host 401s and returns a wildcard Access-Control-Allow-Origin header.
