Croma is an API and MCP server for official government data. Company registries, court cases, sanctions lists, laws and gazettes: 80 sources across the United States, Japan, Brazil, Bolivia, El Salvador, Mexico, Peru and Colombia, plus global web tools. Every endpoint takes the same key, returns the same JSON shape, and is also a tool on the MCP server, so Claude, ChatGPT or your own agent can call it.
