# Daytona

> **WARNING:** Daytona Tier 3+ is required for access to common model provider endpoints. See [Daytona network limits](https://www.daytona.io/docs/en/network-limits/).

## Prerequisites

- `DAYTONA_API_KEY`
- `ANTHROPIC_API_KEY` or `OPENAI_API_KEY`

## TypeScript example

```bash
npm install sandbox-agent@0.5.x @daytonaio/sdk
```

```typescript
import { SandboxAgent } from "sandbox-agent";
import { daytona } from "sandbox-agent/daytona";

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

const sdk = await SandboxAgent.start({
  sandbox: daytona({
    create: { envVars },
  }),
});

try {
  const session = await sdk.createSession({ agent: "claude" });
  const response = await session.prompt([
    { type: "text", text: "Summarize this repository" },
  ]);
  console.log(response.stopReason);
} finally {
  await sdk.destroySandbox();
}
```

The `daytona` provider uses the `rivetdev/sandbox-agent:0.5.2-full` image by default and starts the server automatically.

## Using snapshots for faster startup

```typescript
import { Daytona, Image } from "@daytonaio/sdk";

const daytona = new Daytona();
const SNAPSHOT = "sandbox-agent-ready";

const hasSnapshot = await daytona.snapshot.get(SNAPSHOT).then(() => true, () => false);

if (!hasSnapshot) {
  await daytona.snapshot.create({
    name: SNAPSHOT,
    image: Image.base("ubuntu:22.04").runCommands(
      "apt-get update && apt-get install -y curl ca-certificates",
      "curl -fsSL https://releases.rivet.dev/sandbox-agent/0.5.x/install.sh | sh",
      "sandbox-agent install-agent claude",
      "sandbox-agent install-agent codex",
    ),
  });
}
```
