Overview
OwlBot is a free dictionary API that returns definitions with emojis — fun and fast. Auth is a free API key.
Note (verified 2026-08): from datacenter IPs the API is fronted by a Cloudflare challenge (HTTP 403 “Just a moment…”) — browser/real-IP requests work normally. Retry from a residential network if you hit this.
