About GunSpec
There was no good firearms specification API. So we built one.
The Problem
Firearms data is scattered across wikis, forums, manufacturer sites, and outdated PDFs. Game developers scrape Wikipedia. App builders manually copy specs from brochures. Researchers piece together data from dozens of inconsistent sources. There's no single, structured, developer-friendly API for firearm specifications.
Our Solution
GunSpec.io is a clean REST API that makes structured firearm data accessible. —+ firearms, — manufacturers, — calibers — all available as typed JSON with full-text search, game-ready stat normalization, and transparent data confidence scoring.
