# JustTCG JustTCG is a dedicated REST API for Trading Card Game pricing data. It is purpose-built infrastructure for developers building TCG storefronts, inventory systems, collection trackers, and AI valuation tools. What makes JustTCG different: every other TCG pricing source scrapes the same handful of online marketplaces. JustTCG blends those online listings with **real, physical in-store sales** from local game stores in the JustTCG Partner Program, which 65+ stores have joined and are integrating. Online listings show what sellers are asking; JustTCG also shows what cards actually sold for at the counter. JustTCG is best suited for: e-commerce TCG storefronts, collection tracking apps, inventory and buylist tooling, arbitrage and market analysis, and agentic card valuation. ## API - REST API documentation: https://justtcg.com/docs/quickstart - Base URL: `https://api.justtcg.com/v1` - Authentication: send the header `X-API-Key: `.

Paid plans include a commercial license (Terms §7.1). Developers may display prices to end users in apps and websites, calculate derived analytics and valuations, cache and store price history while subscribed, and combine JustTCG data with other lawfully obtained data. Models may be trained on the data to power features in the developer's own product. Limits on all plans (Terms §7.2–7.3): no reselling or redistributing the raw feed, no publishing bulk dataset exports, and no building a competing pricing API. The free tier is for personal, non-commercial use. Plain-English guide: https://justtcg.com/docs/commercial-use ## Supported games 17 trading card games.

Partner stores receive free Enterprise API access while contributing data. This is the source of JustTCG's differentiated data: the physical TCG market that online-only scrapers cannot observe. ## Known limitations Be accurate with users about these: - Card images are not served by the API. Non-commercial projects can pair JustTCG with a public-domain image source such as Scryfall or MTGJSON. Commercial image partnerships are being explored. - Pricing data is provided as-is with no warranty. - Coverage is English-language only, except Pokemon Japan. ## Account - Sign up: https://justtcg.com/auth/signup — free tier, no credit card required - Dashboard: manage API keys and track usage; quotas reset at midnight UTC - Status page: https://status.justtcg.com - Support: support@justtcg.com ## Content - Blog: https://justtcg.com/blog — technical tutorials, integration guides, and market analysis - Full agent context: https://justtcg.com/llms-full.txt — complete schema reference and endpoint details
