Deck of Cards API

healthy 3,203 Subscribers

A playing-card deck engine as an API. Create a freshly shuffled deck (one or many decks, with or without jokers), draw cards from it, and reshuffle — with full deck state tracked by a deck id so you can deal hands across multiple calls. Each card comes with its code (e.g. AS, 0H), value, suit and a PNG and SVG image URL, so you can render real cards. Draw cards statelessly from a brand-new deck for quick random picks, or keep a deck_id to build a full game. Ideal for card games and game prototypes, Discord bots, teaching and probability demos, and any app that needs a standard 52-card deck. Built on the Deck of Cards service.

MTG API

The complete Magic: The Gathering card database as an API — every card ever printed, backed by Scryfall. Look up a card by name (exact, with automatic fuzzy fallback, e.g. "Black Lotus" → mana cost {0}, type, oracle text, rarity, set, format legalities and current market prices), search the entire pool with Scryfall's powerful query syntax (e.g. q=goblin, q=c:red type:creature cmc<=3, ordered by name/cmc/usd/rarity), pull a random card with an optional filter, browse all 1,000+ sets, and list every mana/cost symbol with its glyph. Each card carries colors, color identity, keywords, power/toughness/loyalty, collector number, artist, release date, high-resolution image and prices in USD/EUR/TIX. Ideal for deckbuilders, collection trackers, price-checkers, Discord bots, judges and MTG content tools.

ISO 18245 Merchant Category Codes (MCC) as an API — the 981 four-digit codes that Visa, Mastercard and other card networks use to classify a merchant's line of business. Look up any code (e.g. 5812 → Eating places and Restaurants, 5411 → Grocery Stores/Supermarkets, 3000 → United Airlines), search by description (e.g. "hotel", "airline", "pharmacy"), filter by IRS-reportable status, or list them all. Each record carries the network/edited description, USDA and IRS descriptions and whether the category is IRS 1099-reportable. Ideal for payments, fintech, expense management, fraud analysis and transaction enrichment.

Poker API

A complete Texas Hold’em toolkit in one fast, fully-local API. Calculate win, tie and equity probabilities for your hole cards against any number of opponents (1–9) on any board — pre-flop, flop, turn or river — using a Monte Carlo simulation with adjustable accuracy. Evaluate the best five-card hand from any five to seven cards and get its rank and tiebreakers, or describe a hand in plain language. Cards use the familiar notation (As, Td, 9h, 2c) and every endpoint works by GET or JSON POST. Pure server-side compute with no third-party upstream, so responses are instant and the service is always available. Ideal for poker trainers and study tools, game developers, hand-history trackers and odds widgets.
