Hearthstone card data as an API, built on the open HearthstoneJSON dataset for Blizzard's collectible card game. Search and filter the full collectible card pool by name, class (Mage, Hunter, Priest, …), card type (minion, spell, weapon, hero), rarity, mana cost, set, minion race or mechanic (Battlecry, Deathrattle, Taunt and more). Fetch any card by its id or name for the full record: cost, attack, health/durability, rules text, flavour text, set, mechanics and rendered card art. List every class and set with card counts, or pull a random card (optionally matching a filter). Real data, no key needed upstream. Ideal for deck builders, collection trackers, card-search tools and Hearthstone fan apps.

Real data, no key needed upstream. Ideal for deck builders, collection trackers, price tools and Lorcana fan apps.

Blackjack Strategy API

Blackjack maths as an API, computed locally and deterministically and exactly — the hand value, the textbook basic-strategy play and the dealer odds, the numbers that hold the house edge to half a percent. The hand-value endpoint scores a hand the way the table does: aces count 11 unless that busts, then 1, so it reports the best total, whether it is soft (an ace still counting 11, safe to hit) or hard, whether it busts, and whether two cards make a blackjack. The strategy endpoint gives the correct basic-strategy action — hit, stand, double or split — for any hand against the dealer's upcard, for the standard 4-to-8-deck game where the dealer stands on soft 17 with double-after-split allowed: 16 against a 10 hits, a pair of 8s always splits, soft 18 doubles against a 6 but hits against a 9, and 11 doubles against everything but an ace. The dealer-odds endpoint gives the dealer's bust probability by upcard — a 5 or 6 busts about 42 % of the time, an ace only 12 % — the reason you stand on stiffs against weak upcards. Everything is computed locally and deterministically, so it is instant and exact. Ideal for blackjack trainers and strategy apps, card-game and casino-game tools, learning aids, and game back-ends. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational — not betting advice; the house always keeps an edge.

Canasta Scoring API

Canasta card-game scoring as an API, computed locally and deterministically and exactly — the point counting that makes Canasta famously fiddly, done for you. The card-value endpoint totals the point value of a hand or meld: a joker is 50, aces and twos 20, eights through kings 10, fours through sevens and black threes 5, and a red three a 100-point bonus card — so a joker, an ace, a king, a seven and a red three come to 185. The bonus endpoint adds the round bonuses: a natural (pure) canasta is 500, a mixed canasta 300, each red three 100 (all four double to 800), going out 100, and going out concealed a further 100 — two naturals, a mixed, three red threes and going out is 1,700. The hand-score endpoint nets it out: the card points you melded, plus the bonuses, minus the card points left stranded in your hand when the round ends. Everything is computed locally and deterministically, so it is instant and exact. Ideal for Canasta apps, online card-room scorekeepers, club and family game-night tools, and learning aids. Pure local computation — no key, no third-party service, instant. Exact integer maths. Live, nothing stored. 3 compute endpoints. Classic Canasta values; rule variants differ.
