A store with one product
We sell one magnet. It costs fifty cents.
Really Big Magnet Co. sells one magnet. It is an emoji, it costs fifty cents, and our API says "you bought a magnet!" when you buy it. This page exists to tell you that there is genuinely nothing more to it.
We built the store in 2026, when software started buying things over open payment protocols. Most of that world was still demos and slideware; we wanted the other thing — the smallest possible store that is completely real. Real product, real price, real 402 payment challenges, real settlement. One product keeps it honest: there is nothing to upsell, nothing to bundle, and no way to get lost in the catalog.
The magnet does not ship, because it does not need to. It arrives in the API response, every time, in well under a second. We are very proud of our logistics.
What we believe
Sell one thing
A store with one product has no dark patterns, no recommendation engine, and no drawer of regret. You came for a magnet. We have exactly that.
Say exactly what it is
The product description, the API docs, and the receipt all say the same thing: fifty cents, one message, one 🧲. If any sentence on this site ever oversells that, we will delete the sentence.
Automation-friendly from day one
No login walls, no CAPTCHAs, no checkout forms. Any HTTP client with fifty cents can buy the magnet in one call.
