# Getting started x402 V1

Here is how to use it on a simple REST service:

```java
@X402PayUSDC(amount = "3") // 3 USDC
@GetMapping("/weather")
public String weather() {
        return "It's sunny!";
}
```

You can have more parameters:

```java
@X402PayUSDC(
  amount = "0.01",
  payTo = "0x209693Bc6afc0C5328bA36FaF03C514EF312287C",
  network = "base-sepolia",
  description = "Access to protected content",
  maximumTimeoutSeconds = 300,
)
@GetMapping("/weather")
public String weather() {
        return "It's sunny!";
}
```

To use our annotation in your spring boot project, edit your maven project and add:&#x20;

```xml
<dependency>
        <groupId>tech.mogami.spring</groupId>
        <artifactId>mogami-x402-spring-boot-starter</artifactId>
        <version>1.1.1</version>
</dependency>
```

or in your Gradle project:

```groovy
dependencies {
    implementation 'tech.mogami.spring:mogami-x402-spring-boot-starter:1.1.1'
}
```
