Built with local game stores

Online listings show the asking price. Stores show what cards actually sell for.

A huge share of the TCG market changes hands at the counter of local game stores, and online-only pricing never sees it. So we asked the stores to share it.

65+ stores have joined the JustTCG Partner Program and are connecting their point-of-sale systems. As each store goes live, its real sales join online market data in our volume-weighted average, so the prices in your app keep getting closer to what cards actually sell for.

It's a trade, not a favor: partner stores get free Enterprise API access while contributing data, so the prices they help build come straight back to their counter.

The rules

What you may build, written down.

Most pricing data leaves the important questions to a support ticket, or to a clause you find out about later. Here are ours, in writing, before you build.

Our boundaries are just as plain: don't resell the raw feed, don't publish bulk dataset exports, and don't build a competing pricing API. The free tier is for personal projects.

Coverage

TCG only. Every game, the same shape.

Conditions, printings, foils, promos and alt arts are first-class fields, not notes buried in a description string.

  • Condition-level pricing

    Near Mint through Damaged are priced separately, never blended into one number.

  • Printing variants

    Foils, alt arts, promos and regional printings are distinct rows with their own prices.

  • One response schema

    Adding another game to your app is a parameter change, not a rewrite.

Pricing

Simple, transparent pricing

Every tier includes complete API access with no hidden costs. Paid plans add the commercial license.

Every paid plan includes a commercial license. The free tier is for personal, non-commercial projects.

Answers

Questions developers ask first

Where the data comes from, what you may build with it, and what the free tier covers.

JustTCG is a dedicated pricing API for Trading Card Games. It provides real-time, condition-specific pricing data for 17 TCGs including Magic: The Gathering, Pokémon, and Yu-Gi-Oh!, so developers and businesses can price cards accurately without maintaining their own scrapers.

Two sources, blended. We analyze real sales data from the major online TCG marketplaces, and through the JustTCG Partner Program, local game stores contribute their real in-store sales. 65+ stores have joined the program and are integrating their point-of-sale systems, and each store's sales join our volume-weighted average as it goes live. The result reflects what cards actually sell for at the counter, not just what they're listed at online.

Three things. First, we are the only TCG pricing API that incorporates real physical in-store sales rather than online listings alone. Second, our v2 beta treats graded cards from PSA, BGS, and CGC as first-class variants, and returns genuine multi-region pricing instead of currency-converted US prices. Third, we are TCG-only — not a general collectibles API with trading cards bolted on.

Our pricing data blends multiple trusted online marketplaces with real in-store sales from our Partner Program network, updated in real-time. Combining listed prices with actual physical transactions gives accurate, regionally-aware market values based on card condition, printing type, and current market trends.

17 games: Magic: The Gathering, Pokémon, Pokémon Japan, Yu-Gi-Oh!, Disney Lorcana, One Piece Card Game, Digimon Card Game, Flesh and Blood, Grand Archive, Gundam Card Game, Star Wars: Unlimited, Union Arena, UniVersus, Sorcery: Contested Realm, Riftbound: League of Legends, Dragon Ball Super: Fusion World, and hololive OFFICIAL CARD GAME. Every game includes condition-specific and printing-specific pricing.

No. Create an account and your API key is issued immediately, with no application, approval queue or credit card. Start on the free tier, and upgrade to a paid plan when you're ready to ship commercially.

Create a free account, and you'll receive an API key immediately — no credit card required. Authenticate by sending an X-API-Key header to https://api.justtcg.com/v1. The quickstart guide at justtcg.com/docs/quickstart walks through your first request, and an official JavaScript/TypeScript SDK is available on npm as justtcg-js.

The free tier includes 1,000 API calls per month with a 100-call daily cap and a rate limit of 10 requests per minute. It covers all supported TCGs and requires no credit card, which makes it suitable for testing and small projects. Paid plans start at $19 per month for 10,000 monthly calls.

Yes. JustTCG runs a hosted Model Context Protocol server at https://mcp.justtcg.com, so agents in Claude, Claude Code, Cursor, VS Code, and OpenCode can query live pricing data directly. It exposes tools for games, sets, and card lookups, and authenticates with the same API key as the REST API.

Yes, on any paid plan. The commercial license lets you display prices to your users, calculate derived analytics and valuations, cache and store price history while subscribed, and combine our data with other lawful sources. That covers apps, websites, marketplaces, SaaS tools, internal tools and AI agents. The only limits: you can't resell or redistribute the raw feed, publish bulk dataset exports, or build a competing pricing API. The free tier is for personal, non-commercial projects. Full details: justtcg.com/docs/commercial-use.

Yes, for your own product. On a paid plan you can train models that power features in your own app, tool or agent, such as price predictions, deal alerts or collection valuations. You can't use the data to train or build a substitute pricing API or data feed, and you can't export it as a dataset.

You can upgrade your plan at any time through your dashboard. Visit the billing section, select your desired plan, and follow the checkout process. Your new plan takes effect immediately, and prices are exclusive of sales tax, which is calculated at checkout based on your billing location.

We accept all major credit cards (Visa, MasterCard, American Express). All payments are processed securely through Stripe, ensuring your payment information is protected.

Yes, we offer a 30-day money-back guarantee for all paid plans. If you're not satisfied with our service, simply contact our support team within 30 days of your purchase for a full refund.

You can reach our support team through email at [email protected]. We typically respond within 24 hours during business days. Paid plans include priority support with faster response times.
