Koot — by Datakoot
One call that does the work of many lookups. Koot briefs your AI agent on a software stack, a public company, a domain or a US place, and answers in one line, with the details underneath.
https://koot.datakoot.com/mcp
No API key for the free briefs (5 a day). Built on the nine Datakoot official-data servers.
