accept payments from ai agents

An AI agent pays an online store by sending USDC stablecoin payments after the store confirms the price, the stock and the delivery address. The store needs no card terminal and no human at the checkout for that order. The store only has to publish accurate prices and handle the order like any other paid order, with payment routed through the Integrator.

What accepting a payment from an AI agent means

An AI agent is software that buys on behalf of a person or a business. When the agent buys from an online store, the store receives money from a buyer that is not a person at a keyboard. The goods stay the same. The buyer changes.

Most stores take payment through a checkout page built for shoppers. An agent cannot use that page the way a shopper does. It can read a price and submit an order, but it needs a payment method that does not depend on a card form. Stores that want agent orders need a second path next to the normal checkout.

That path does not replace the store's own systems. The store keeps its catalogue, its stock records and its fulfilment process. Only the payment step changes for agent buyers.

How an order moves from the agent to the store

The agent begins with a product, a quantity and a delivery address. It asks the store for the current price. The store answers with the total, the stock status and the order reference that the agent must quote back.

The flow has three steps:

  • The agent selects items and a delivery address from the store's published data.
  • The store quotes the total in USDC stablecoin payments and holds the stock for that quote.
  • The payment settles, and the store fulfils the order as it fulfils any paid order.

The store should set a clear expiry on each quote. An agent that pays after a price change gets a failed order, not a surprise charge. The store decides how long a quote stays valid, and it should write that rule down before launch.

Pricing and the minimum order

The Integrator charges 0% fee during the pilot. The store should read that figure against its own margin before it turns the agent path on. A margin that works for card orders can fall short once a fee applies to every agent order.

The path requires a minimum order of $1.00. Small baskets therefore fall outside it. A store that sells low-priced items can bundle them, raise the unit price, or keep those baskets on the normal checkout.

Store owners should also check how the minimum interacts with delivery costs. A basket that clears the minimum on paper can still lose money once shipping is added.

Where payments settle

Payments settle on Base and Tempo. Settlement means the USDC stablecoin payment arrives on that network and the store can match it to the order total. The store then releases the goods.

Stores that report revenue in a different currency need an accounting step of their own. The buyer pays in USDC stablecoin payments, so the store decides how to record that receipt in its books. The accountant should review the treatment before the first live order.

Settlement also sets the timing. The store should not ship before the payment has settled. A store that ships early takes on the risk of a failed payment without any way to recover the goods.

What the store prepares before launch

Agents read data more literally than shoppers do. A store that works for people can still fail an agent buyer. Three preparations matter most:

  • A product catalogue with exact prices, units and stock counts that the store updates on a set schedule.
  • A shipping policy written so that a machine can apply it to a delivery address without a phone call.
  • A returns rule in plain terms, since the buyer acts for someone else and the terms must say who answers for the purchase.

The store should test the catalogue data with a small set of products first. Missing units, stale stock counts and vague shipping zones cause most failed orders.

Limits and risks the store should accept knowingly

An agent buys only within the limits its owner set. The store cannot see those limits. If the store declines an order, the agent must choose another seller or ask its owner. The store should expect declined orders and plan for them.

Fraud checks still matter. An agent can be compromised, copied or pointed at the wrong store. Stores should flag unusual baskets, repeated failed quotes, and delivery addresses that change from order to order. A flagged order can wait for manual confirmation, and the store should say so in its terms.

The person behind the agent usually answers for the purchase. The store's terms should name that person as the buyer, so that disputes do not rest on the agent itself.

A rollout that limits the damage

Start with one product line that has stable prices and low return rates. Watch the first orders from quote to delivery. Check each stage: quote accuracy, settlement timing, shipping, and the final customer message.

Compare the margin after the fee with the margin on card orders for the same products. Expand to more products only when the comparison supports it. A slow expansion gives the store time to fix catalogue errors before they multiply across the range.

Keep the normal checkout running during the rollout. Agent buyers and human buyers can share the same catalogue and stock. Only the payment path differs.

Fees and limits

  • Cost to the store: 0% fee during the pilot.
  • Minimum order: $1.00.
  • Rails: Base and Tempo.

FAQ

Can an AI agent pay an online store without a card?

Yes. The agent pays in USDC stablecoin payments through the Integrator path, so the store does not need a card terminal for that order.

What is the minimum order on this path?

The path requires a minimum order of $1.00. Smaller baskets stay on the normal checkout or need to be bundled.

What does the Integrator charge?

The Integrator charges 0% fee during the pilot. The store should compare that figure with its own margin before it enables the path.

Which networks do payments settle on?

Payments settle on Base and Tempo. The store should release goods only after the payment has settled.

Does the store need a new website to accept agent orders?

The store needs accurate prices, stock counts and shipping rules that a machine can read. Whether that requires changes to the existing site depends on how the catalogue is already published.

Who is responsible if an agent buys the wrong item?

The store's terms decide that. The terms should name the person behind the agent as the buyer and state the returns rule in plain language.
