Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

const url = "https://db.ygoprodeck.com/api-guide/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

import requests

url = "https://db.ygoprodeck.com/api-guide/"
headers = {}

response = requests.get(url, headers=headers, timeout=30)
response.raise_for_status()
data = response.json()
print(data)

curl "https://db.ygoprodeck.com/api/v7/cardinfo.php?name=Dark+Magician"

What Can You Build?

// Fetch character or game data
const response = await fetch(`https://db.ygoprodeck.com/api-guide`);
const data = await response.json();
const items = data.results || data.characters || data.data || [data];
const characters = Array.isArray(items) ? items : [items];
characters.slice(0, 5).forEach(c => {
  console.log(`🎮 ${c.name || c.title}: ${c.description || 'No description'}`);
});

// Get random trivia or game fact
const response = await fetch(`https://db.ygoprodeck.com/api-guide`);
const data = await response.json();
const trivia = data.results?.[0] || data;
console.log('Trivia:', trivia.question || trivia.text || JSON.stringify(trivia));
if (trivia.correct_answer) {
  console.log('Answer:', trivia.correct_answer);
}

// Fetch game statistics
const response = await fetch(`https://db.ygoprodeck.com/api-guide`);
const data = await response.json();
console.log('Game data from Yu-Gi-Oh!:', data);
const entries = Array.isArray(data) ? data : data.data || data.results || [data];
entries.slice(0, 5).forEach((entry, i) => {
  console.log(`#${i+1}: ${entry.name || entry.title} - Score: ${entry.score || 'N/A'}`);
});

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.

{
  "error": "No card matching your query was found in the database. Please see https://db.ygoprodeck.com/api-guide/ for syntax usage."
}
