First request with Java

List your own copiers to check connectivity and identity without creating a terminal or placing a trade.

1. Install

Requires JDK 11+ and Maven 3.8+. These instructions build from source; they do not assume a registry release exists.

git clone https://github.com/MetaRPC/JavaCopier.git
cd JavaCopier
mvn test
mvn dependency:copy-dependencies
javac -cp "target/classes" -d target/examples examples/ListCopiers.java

On Windows use ; instead of : in Java classpaths.

2. Set your owner key

export MRPC_API_KEY='your-owner-key'

$env:MRPC_API_KEY = 'your-owner-key'

Use the real owner API key, not a broker password, terminal ID or TRIAL. Read authentication if access is refused.

3. Run

java -cp "target/examples:target/classes:target/dependency/*" ListCopiers

Source: examples/ListCopiers.java.

import pro.mrpc.copier.CopierService;
import pro.mrpc.copier.Models;
public class ListCopiers {
    public static void main(String[] args) {
        try (CopierService service = new CopierService("https://copy.mrpc.pro", System.getenv("MRPC_API_KEY"))) {
            Models.ListReply result = service.list();
            if (!result.ok) throw new IllegalStateException(result.error);
            for (Models.CopierSummary item : result.copiers) System.out.println(item.id + ": paused=" + item.paused);
        }
    }
}

A successful empty list means this owner has no copiers. Treat failed requests as errors, not empty accounts.

4. Prepare a demo workflow

Read the lifecycle guide, then choose sizing. Existing replication examples under examples/ are advanced integration examples: they may provision accounts and trade. Inspect them and their cleanup before running with disposable demos. List is the default starting point.
