An Agent Can Now Buy a Gift Card. About Twenty Wallets Have.

Bitrefill has sold gift cards, phone credit, and eSIMs for cryptocurrency since 2014, and in June it started selling them to software. There is now a set of endpoints at api.bitrefill.com where an AI agent can search more than 8,000 products across 180-plus countries, price one, generate an invoice, pay it in USDC, and collect a redemption code, with no account and no human in the loop. We ran the whole path. It works. In the census window since, about twenty wallets have paid the step that matters.

Start with the company, because it changes how you read the traffic. Bitrefill is not a crypto-native startup that built itself around agent payments. It is a decade-old merchant, registered in Stockholm as Airfill Prepaid AB, that has spent those years letting people buy real-world value with Bitcoin, Lightning, and stablecoins. By its own count it clears 50,000 crypto payments a day. What it added, quietly, was an x402 layer over the same catalog: the store, reachable by machines that pay per call.

The mechanics are a state machine, not a single metered call. A discovery endpoint returns the storefront's rules. A search endpoint takes a brand and a country and costs two-tenths of a cent. A detail endpoint returns a product's packages and recipient requirements for a tenth of a cent. Then the agent creates an invoice and pays it. The small endpoints are navigation. The money is in one step, invoice/pay, where the agent settles the actual cart, an amount the envelope we triggered put at a thousand USDC. Payment clears on Base, Arbitrum, Polygon, or Solana, the buyer's choice, and the redemption code comes back only after the paying wallet signs for it. One honest caveat: none of this is a single round-trip. A purchase is a chain of paid HTTP calls, each returning a 402 that tells the machine the price and the exact shape of what to send next.
