Quickstart

Overview

The JustTCG API provides real-time pricing data for trading card games including Magic: The Gathering, Pokémon, Yu-Gi-Oh!, Disney Lorcana, One Piece TCG, Digimon, and Union Arena. Our API is designed to be simple, fast, and reliable.

Using Node.js or TypeScript?We strongly recommend the official justtcg-js SDK. It provides type safety, automatic authentication, and cleaner data models. View SDK install →

Authentication

Keep your API key secure.Never expose it in client-side code. If you suspect your key has been compromised, regenerate it immediately from the dashboard.
