None of them built Pennysleeve, reviewed it, or endorses it. Every request Pennysleeve sends them says what it is and how to reach the person who runs it, so an operator who wants different traffic from Pennysleeve can ask for it directly instead of guessing where an anonymous request came from.

Stripe hosts the payment and billing management pages.

EDHREC

The Commander deck-popularity rank behind Decks 30d on the Watchlist, the Rising cards page and What to sell. It reaches this app through Scryfall, under an arrangement between the two sites, so Pennysleeve never queries EDHREC on its own.

pokemontcg.io

The Pokemon card catalog and each set's symbol.

JustTCG

Pokemon prices.

Pokemon card images.

U.S. Census Bureau

Representative ZIP Code locations used for approximate straight-line Find cards distance estimates.

OpenStreetMap Nominatim

Turns a shop's address into a point on the map, so a trip's mileage can be worked out.

OSRM

Turns two of those points into a driving distance, which is the mileage figure itself.

17Lands

Draft play data for the Limited tab on Rising cards, once it loads.

Thank you to all 13. Pennysleeve does not exist without the data they give away.
