# Introduction

> The Croma API in one page: court cases, criminal records, company registries, vehicles and laws from 36 official sources in Colombia, Peru and Mexico.

Croma is an API for government data. Court cases, criminal records, company
registries, vehicle records, laws: 36 sources across Colombia, Peru, and
Mexico, plus global web tools. Every endpoint takes the same key, returns the
same JSON shape, and is also a tool on the [MCP server](/mcp-server).
