Catalog measurement

Exact counts use the method printed beneath each value.

Page cache: one hour after a successful measurement

Distinct games: 90
Distinct expansions: 4,617
Single-card records: 459,247
Non-sealed SKU entries: 7,308,626

The one-hour cache is this page's measurement cache, not a claim about upstream marketplace ingestion cadence.

Atomic dataset claims

What each dataset claim means.

Each row states one independently citable capability and links to the narrowest supporting public page.

Endpoint evidence

Access by endpoint family.

“Access” is the minimum ongoing tier for the specific row, not the whole source family. Signup credits can evaluate catalog and card-recognition requests.

Plan distinctions

Product pricing is not SKU pricing.

Business unlocks product-level pricing, sales history, historic prices, and multi-marketplace pricing. Unlimited adds live TCGPlayer listings and SKU-level pricing.

Plan	Monthly calls	Catalog	Product pricing	Sales/history	Marketplace pricing	Live listings	SKU pricing
Hobby£99/month	10,000	Included	—	—	—	—	—
Business£199/month	50,000	Included	Included	Included	Included	—	—
Unlimited£499/month	Uncapped	Included	Included	Included	Included	Included	Included

New accounts receive 100 evaluation credits without a card; paid endpoint gates still apply.

Methodology

How the catalog counts are produced.

Games: count distinct categoryId values.
Expansions: count distinct groupId values.
Cards: count documents where isSingle is true.
SKU variants: sum SKU-array lengths on records where isSealed is not true.

Successful measurements are cached in the web process for one hour. On measurement failure, the page uses the published fallback and retries sooner. This describes presentation logic, not source ingestion.

Freshness boundary

No invented universal cadence.

TCGAPIs exposes several independently maintained datasets. This page therefore does not state that every catalog, price, listing, sale, or board-game record updates on one schedule.

When a response includes a source or record timestamp, use that value for record-level freshness. Use this page's review date only to date the published definitions and access matrix.

Commercial SLAs, where contracted, are plan terms and are not replaced by this public methodology page.

Source definitions

Names used precisely.

The published product-wide source list is broader than any one endpoint family.

TCGPlayerCardmarketCardtraderCardsyncedManapoolCardKingdomCardsphere

TCGPlayer: The identity and market-data family used for TCGPlayer category, expansion, product and SKU identifiers, product prices, sales history, and seller listings exposed by the corresponding endpoints.
Cardmarket: A separate game → expansion → single catalog with product price-guide fields, including foil and non-foil values where present.
CardTrader: A separate game → expansion → blueprint catalog with variant price aggregates by print type and condition.
Trend-provider layer: A normalised snapshot/history surface. The current public provider enum is cardhoarder, cardkingdom, cardmarket, cardsphere, manapool, and tcgplayer; accepted listing, finish, availability, and currency vocabularies are returned by the public providers endpoint.
Board-game catalog: Board-game and expansion records with identity, rankings, ratings, player and play-time fields, mechanics, categories, credited people, and images.

Known limitations

What this evidence does not prove.

Coverage is dataset-specific. A product can exist in a catalog without having a price, listing, sale, SKU, cross-reference, or provider record.
This page does not assert one global upstream update cadence. “Current” and “live” describe the endpoint dataset; they are not a numeric freshness SLA.
Use timestamps returned by a record when present. Do not substitute the page review date for an individual record timestamp.
The product-wide marketplace list is not the same as the accepted trend-provider enum. Query the public trend providers endpoint before applying a provider filter.
Currencies are source-dependent. The trend provider vocabulary currently lists USD and EUR; clients should read each response rather than assume conversion.
A missing row or 404 means the requested identifier has no record in that endpoint response. It does not prove that the item is absent from every source.
Counts change as catalog records change. Cite the measurement timestamp and methodology with any exact count copied from this page.
TCGAPIs is independent and is not affiliated with, endorsed by, or sponsored by TCGPlayer or eBay.
