# Machine payments

Enable machine-to-machine payments with Stripe.

Use machine payments to let your agents pay for resources programmatically (for example, for API calls or services). As a business, you can use Stripe to accept machine payments in crypto directly into your Stripe balance.

|  |
| **For sellers** | If you have growing traffic and interest from agents, enable pay-per-use business models as low as 0.01 USDC. If your product is primarily an API, sell individual requests to agents, or restrict access to data and content with a paywall. |
| **For agents**  | As an alternative to setting up an account and getting an API key, your agent can interact with services on demand and pay per invocation. Your agents only need access to a crypto wallet.                                                   |

## Features

Machine payments integrate with your existing Stripe integration.

|  |
| **Stripe payments**   | Payments land directly in your Stripe balance and settle in fiat. Metrics, reporting, and multi-currency payouts work the same as any other payment in Stripe.                                                                                      |
| **Refunds**           | Refunds are available through the API and in the Dashboard. For stablecoin transactions, we return funds to the “From” wallet address of the token transfer.                                                                                        |
| **Microtransactions** | Individual charges can be as low as 0.01 *USDC* (A cryptocurrency that's pegged to the value of a fiat currency or other asset in order to limit volatility).                                                                                       |
| **Private**           | Stripe uses a unique deposit address for each payment, which reduces on-chain visibility of your processing volume.                                                                                                                                 |
| **US availability**   | Card and wallet payments through [SPTs](https://docs.stripe.com/agentic-commerce/concepts/shared-payment-tokens.md) are available nationwide to developers with a US legal entity. Stablecoin payments are available in all states except New York. |
