Data Sources & Attribution

Manufacturers

• Panini America. Product information pages on paniniamerica.net publish per-product hit and parallel odds. All Panini brand names (Prizm, Select, Donruss, Optic, Mosaic, National Treasures, etc.) are trademarks of Panini America. We display their disclosed odds for the limited purpose of consumer transparency in card-break analytics.
• Topps / Fanatics Collectibles. Set composition data, where used, is taken from publicly-disclosed pack-and-box configurations and published product information.
• The Pokémon Company / The Pokémon Company International. “Pokémon” and Pokémon character names are trademarks of Nintendo / Creatures Inc. / GAME FREAK inc. The Pokémon Company does not publish official pull rates; we use community-aggregated estimates (cited below) for derived odds.
• Wizards of the Coast. Magic: The Gathering pack-slot structures and rarity definitions are documented by Wizards of the Coast. “Magic: The Gathering” is a trademark of Wizards of the Coast LLC.

Public APIs

• Scryfall. Magic: The Gathering card metadata (set composition, rarity) is sourced via the Scryfall API. Scryfall is unaffiliated with Wizards of the Coast. We access the API in accordance with Scryfall's published guidance (identifying User-Agent, rate-limited requests, cached responses).
• Pokémon TCG API. Pokémon card metadata is sourced via pokemontcg.io. The Pokémon TCG API is a free community-maintained service and is not affiliated with The Pokémon Company. We comply with their published rate-limit policy.

Community pull-rate aggregations

Where a manufacturer declines to publish official odds — most notably for modern Pokémon TCG sets — we surface derived odds calibrated against public pack-opening data compiled by:

• TCGplayer Infinite (editorial pull-rate articles)
• Bulbapedia (set rarity definitions, available under Creative Commons Attribution-ShareAlike 2.5)
• DigitalTQ, Cardshoplive, PokemonCoders pull-rate reports
• Cardboard Connection (sports-card product info reproductions)

Derived odds tagged with community-source confidence are provided for informational purposes and should not be treated as manufacturer-guaranteed values.

How we use this data

• We fetch upstream data only with an identifying User-Agent and at rates each source publishes as permitted.
• We honour robots.txt directives on every host we contact and skip any path that disallows our agent.
• We cache responses (manufacturer-direct for up to 30 days, community for up to 7) to minimize total requests.
• Every stored odds value is tagged with its source and a confidence rating, so a consumer reviewing the underlying data can see provenance at any time.
