OwlBot

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.

Quick Start

Definition (replace YOUR_TOKEN):

curl "https://owlbot.info/api/v4/dictionary/hello" \
  -H "Authorization: Token YOUR_TOKEN"

{
  "word": "hello",
  "pronunciation": "həˈlō",
  "emoji": "👋",
  "definitions": [
    { "type": "interjection", "definition": "used as a greeting", "example": "hello there!", "image_url": "https://..." }
  ]
}

Authentication

FAQ

Is OwlBot free? Free tier with a daily allowance; more is paid.

Why 403 from my server? The API sits behind a Cloudflare challenge (verified) — residential/browser requests work.
