# The Card Pyramid > A satirical UK playing-card marketplace — a pyramid scheme where the product is actually cards. We open sealed Bicycle® decks, sell the exact cards you want, and price each order by how much damage it does to the remaining stock. Built on Suluk (Astro + Hono + Drizzle on Cloudflare). The Card Pyramid breaks fresh decks to sell singles, gaffs, fragments, and liquidation lots — the products below are real stock. Every order is priced by a transparent formula (card subtotal + deck-break fee + inventory-stress fee − orphan offset) and the cost of every request is metered. The 'pyramid scheme' is a joke about pricing: no investment, no returns, no recruitment. ## Products - [Bicycle Red 808 · Sealed](https://thecardpyramid.saastemly.com/products/bicycle-red-808): A factory-sealed red-back 808 deck. The top of the pyramid — buy it whole, or make us break it for the cards you actually want. - [Bicycle Blue 808 · Sealed](https://thecardpyramid.saastemly.com/products/bicycle-blue-808): A factory-sealed blue-back 808 deck. The other apex. Same stock, opposite colour — and a different set of orphans when it breaks. - [Ace of Spades](https://thecardpyramid.saastemly.com/products/ace-of-spades): The single everyone asks for. Pulled from a deck on demand — which is why the first one out is the one that forces a break. - [Court Card · King / Queen / Jack](https://thecardpyramid.saastemly.com/products/court-card): Pick your court. High-demand faces in red or blue back. Choose the exact card; we worry about the deck it leaves behind. - [Matching Jokers · pair](https://thecardpyramid.saastemly.com/products/matching-jokers): Two jokers with matching backs, same print run. Cheap to want, awkward to source — jokers are the cards a break always strands. - [Matching Red Backs · ×5](https://thecardpyramid.saastemly.com/products/matching-red-backs): Five red-back cards from the same run — utility stock for absorbing a broken deck. Buy these and you rebalance our shelf. - [Force Cards · ×10](https://thecardpyramid.saastemly.com/products/force-cards): Ten identical force cards. Magicians' utility duplicates — the kind of stock that piles up every time a deck is broken. - [Double-Backer Gaff](https://thecardpyramid.saastemly.com/products/double-backer): A double-backed gaff card — red on one side, blue on the other. Pick a back. Made from two decks that will never be whole again. - [Off-Balance Leftover · partial run](https://thecardpyramid.saastemly.com/products/off-balance-leftover): A partial run of consecutive cards from a single broken deck. Strange, incomplete, cheap. The pyramid's awkward middle. - [Mismatched Index Lot](https://thecardpyramid.saastemly.com/products/mismatched-index-lot): A handful of cards with mismatched indices and backs — leftovers that don't add up to anything. Take them off our hands. - [Bagholder Bundle · Mystery 20](https://thecardpyramid.saastemly.com/products/bagholder-mystery-20): Twenty cards we couldn't sell any other way. No promises about which. The lower the layer, the stranger the bargain. - [Liquidation Lot · Whatever's Left](https://thecardpyramid.saastemly.com/products/liquidation-lot): The whole bottom shelf, boxed. Weird, heavy, dirt-cheap by the card. When the pyramid gets top-heavy, this is the release valve. ## Blog - [How the fall works](https://thecardpyramid.saastemly.com/blogs/how-the-fall-works): Every order pushes cards down the pyramid. Here's the whole margin system in one diagram — and why the bottom is where the bargains live. - [Why bagholders get the best deals](https://thecardpyramid.saastemly.com/blogs/bagholder-economics): The cheapest cards on the site are at the bottom on purpose. If you take the leftovers, you're doing us a favour — and we pay you for it. - [Deck-break economics](https://thecardpyramid.saastemly.com/blogs/deck-break-economics): What the deck-break fee and the inventory-stress fee actually pay for — and how to dodge both with one click. ## Developers - [API reference (OpenAPI v4)](https://thecardpyramid.saastemly.com/reference): The live, contract-projected reference - [OpenAPI document](https://thecardpyramid.saastemly.com/openapi.json): The canonical v4 document - [Typed SDK](https://thecardpyramid.saastemly.com/sdk.ts): A generated ofetch SDK - [Cost ledger](https://thecardpyramid.saastemly.com/cost): Real per-request cost, metered — the same fall-managing math that prices each card order ## MCP (agent tools) - [MCP server](https://thecardpyramid.saastemly.com/mcp): Model Context Protocol endpoint (Streamable-HTTP, POST JSON-RPC). The same OpenAPI v4 contract projected into read-only tools — list/get products, posts, and categories. Call `initialize` then `tools/list`. ## Pages - [Pricing](https://thecardpyramid.saastemly.com/pricing) - [About](https://thecardpyramid.saastemly.com/about) - [FAQ](https://thecardpyramid.saastemly.com/faqs) - [Contact](https://thecardpyramid.saastemly.com/contact)
