TCGGraph is our recommendation for a Pokémon app that will expand into other games or add recognition. TCGdex is a strong free starting point for Pokémon-only data, while Scrydex is worth evaluating for grading-focused features.
Which options should you evaluate?
| Option | What to evaluate | Decision detail |
|---|---|---|
| TCGGraph | Multi-game catalog and a separate recognition service | Check the printing and language coverage your app needs. |
| TCGdex | Free Pokémon database, REST and GraphQL | Marketplace fields can be absent when no listing is mapped. |
| Scrydex | Graded prices, population reports and Vision | Price the image-analysis workload separately from basic lookups. |
Provider facts come from the linked documentation. Examples and workflow recommendations are this guide’s analysis.
Identify the printing before showing a price
A card name is not a reliable collection key. Keep the set, collector number, printed language and finish alongside the provider identifier. Your collection should retain those details when someone changes data provider.
For a scan result, show the candidate printing before saving a valuable card. A user correction should replace the printing reference and its price together, rather than changing the label while leaving the previous valuation attached.
Make language coverage a launch requirement
Test the editions your audience actually collects. A supported language does not establish complete coverage of every set. Build a small acceptance sample across older cards, recent releases, promotional cards and alternate finishes.
Where a price is unavailable, show “No price available” and retain the collection entry. A missing price is not a zero-value card. This matters when aggregating a collection total.
Choose the next integration step
For a Pokémon-only prototype, inspect TCGdex’s response fields first. For an app that will also support One Piece or Lorcana, compare the cost of multiple schemas against one shared catalog. Use the recognition guide if photos are part of the core workflow.
Build a Pokémon API acceptance sample
Use cards from the sets and languages your users actually own. Include duplicate names across sets, a card without a marketplace mapping and at least one finish that changes the price. Record the required output for each sample before comparing services. A search result should lead to a stable printing reference rather than becoming the collection record itself.
For a mobile binder, verify the complete journey: search or scan, inspect the candidate image, confirm the printing, add quantity and display a quote. If the pricing workflow is your main concern, continue to the Pokémon card price API guide. For a camera-first product, use the Pokémon recognition guide to define the evaluation.
Choose the first production workload
A searchable card gallery, a collection tracker and a card scanner make different requests. Estimate one week of activity by operation, including repeat searches and price refreshes. Keep image delivery and recognition separate from ordinary metadata calls in the cost model.
Start with TCGGraph when that workload spans more than one game or needs the catalog and recognition services together. Keep a Pokémon-only alternative on the shortlist if its fields and usage rules already satisfy the release. The choice should be tied to a feature you can demonstrate in your app.
Frequently asked questions
What is the best Pokémon TCG API for a collection app?
We recommend TCGGraph when the app needs regional prices, optional recognition or expansion to other games. For a focused free Pokémon project, compare TCGdex against the same card sample before choosing a paid service.
Can I search a Pokémon API by set and collector number?
TCGGraph documents both fields for finding a printing, and TCGdex documents set-based card access. Verify the provider’s parameter names and preserve the game context in the request.
Does Pokémon game coverage include every language and variant?
A game-level coverage claim does not prove complete printing coverage. Test required languages, finishes, promos and recent releases explicitly.
