x402 by GSC is here.

The old way to pay on the internet was built for a person with a browser — the same person who read the PDF catalogue and filled in the web form. Those artifacts have been replaced, and so has the way they got paid for. The workforce doesn't buy like that anymore. It sends an agent, and an agent doesn't keep a wallet in a drawer — it pays inside the request.

• No account to open.
• No card on file.
• No invoice, no approval queue, no wait.

The agentic era is here.

The internet always had a door marked "Payment Required" — status 402 in the Hypertext Transfer Protocol, written in the 1990s and left empty for thirty years. x402 is that door, finally open: an open, neutral standard that lets a machine ask, be told what it owes, pay, and be served in one exchange. The rails of the old economy joined it — Visa, Mastercard and American Express — alongside Google, Amazon Web Services and Cloudflare.

• Open — anyone can build on it.
• Neutral — tied to no single network.
• Instant — money moves at the speed of the request.

When the card networks and the cloud agree on a standard, it isn't a trend. It's the new floor.

Your agent calls for a record or an order. The door answers with what it owes. Your agent pays on the rail and is served — with a signed receipt it can show anyone. Seconds, not a procurement cycle.

• The agent asks.
• The agent pays.
• The agent is served, receipt in hand.

No human in the payment. A human still signs the order.

Every GSC door answers a payment request the same way, on the public rail, today. Settlements have landed. Receipts resolve forever. Any agent on the internet can pay a GSC door this afternoon and hold the proof by tonight.

• One standard on every door.
• Settlements landed, verified on the chain.
• Every receipt kept, signed by GSC, resolving forever.

Tomorrow, already in place.

When the buyer's agent is ready to pay for an order, your brand's side is already ready to be paid — in any of the 20 countries, on one rail, with nothing added later. Every settlement leaves a receipt your finance team can read and your agent can defend. And a person still signs every order before it ships.

• Settle at the moment of the order, in every market.
• A receipt finance can file, an auditor can read.
• A person on every order, as always.

You built the brand. We built the rail under it.

Every order a GSC AI Agent places is ready to settle here the moment the buyer's side is. The agent that sells your product is the same agent that gets it paid — one counterparty, one receipt, one signature.

• The brand's agent offers.
• The buyer's agent pays.
• A person signs. The order ships.

Sell-side and pay-side, one agent.

AI Agents →

The record is the thing worth paying for, and it already knows how to be paid. Reads answer at the door; when an agent wants the record itself, it pays here and keeps the receipt. The graph is the object; the receipt is the proof.

• Every record read from the graph can be paid for here.
• Every receipt points back to the record it bought.
• Every settlement signed by GSC.

Every hub answers the same door — priced by the record, paid by the agent.

Give your agent the address in the card, and it does the rest: asks, pays, and is served, with a receipt it can show anyone. Try it with a single request today. Tell us what your agents need to pay for, and a person answers.
