## Prerequisites

- `VERCEL_OIDC_TOKEN` or `VERCEL_ACCESS_TOKEN`
- `ANTHROPIC_API_KEY` or `OPENAI_API_KEY`

## TypeScript example

```typescript
import { Sandbox } from "@vercel/sandbox";
import { SandboxAgent } from "sandbox-agent";

const envs: Record<string, string> = {};
if (process.env.ANTHROPIC_API_KEY) envs.ANTHROPIC_API_KEY = process.env.ANTHROPIC_API_KEY;
if (process.env.OPENAI_API_KEY) envs.OPENAI_API_KEY = process.env.OPENAI_API_KEY;

const sandbox = await Sandbox.create({
  runtime: "node24",
  ports: [3000],
});

const run = async (cmd: string, args: string[] = []) => {
  const result = await sandbox.runCommand({ cmd, args, env: envs });
  if (result.exitCode !== 0) {
    throw new Error(`Command failed: ${cmd} ${args.join(" ")}`);
  }
};

await run("sh", ["-c", "curl -fsSL https://releases.rivet.dev/sandbox-agent/0.3.x/install.sh | sh"]);
await run("sandbox-agent", ["install-agent", "claude"]);
await run("sandbox-agent", ["install-agent", "codex"]);

await sandbox.runCommand({
  cmd: "sandbox-agent",
  args: ["server", "--no-token", "--host", "0.0.0.0", "--port", "3000"],
  env: envs,
  detached: true,
});

const baseUrl = sandbox.domain(3000);
const sdk = await SandboxAgent.connect({ baseUrl });

const session = await sdk.createSession({ agent: "claude" });

const off = session.onEvent((event) => {
  console.log(event.sender, event.payload);
});

await session.prompt([{ type: "text", text: "Summarize this repository" }]);
off();

await sandbox.stop();
```

## Authentication

Vercel Sandboxes support OIDC token auth (recommended) and access-token auth.
See [Vercel Sandbox docs](https://vercel.com/docs/functions/sandbox).
