### TypeScript Example

```typescript
import OpenAI from "openai";

const openai = new OpenAI({
  apiKey: "YOUR_API_KEY",
  baseURL: "https://api.morphllm.com/v1",
});

const instruction = "I will add error handling to prevent division by zero";
const originalCode = "function divide(a, b) {\n  return a / b;\n}";
const codeEdit = "function divide(a, b) {\n  if (b === 0) {\n    throw new Error('Cannot divide by zero');\n  }\n  return a / b;\n}";

const response = await openai.chat.completions.create({
  model: "morph-v3-fast",
  messages: [
    {
      role: "user",
      content: `<instruction>${instruction}</instruction>\n<code>${originalCode}</code>\n<update>${codeEdit}</update>`,
    },
  ],
});

const mergedCode = response.choices[0].message.content;
```

### Python Example

```python
import os
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.morphllm.com/v1"
)

instruction = "I will add error handling to prevent division by zero"
original_code = "function divide(a, b) {\n  return a / b;\n}"
code_edit = "function divide(a, b) {\n  if (b === 0) {\n    throw new Error('Cannot divide by zero');\n  }\n  return a / b;\n}"

response = client.chat.completions.create(
    model="morph-v3-fast",
    messages=[
        {
            "role": "user",
            "content": f"<instruction>{instruction}</instruction>\n<code>{original_code}</code>\n<update>{code_edit}</update>"
        }
    ]
)

merged_code = response.choices[0].message.content
```

### cURL Example

```bash
curl -X POST "https://api.morphllm.com/v1/chat/completions" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ 
    "model": "morph-v3-fast",
    "messages": [
      {
        "role": "user",
        "content": "<instruction>I will add error handling to prevent division by zero</instruction>\n<code>function divide(a, b) {\n  return a / b;\n}</code>\n<update>function divide(a, b) {\n  if (b === 0) {\n    throw new Error(\"Cannot divide by zero\");\n  }\n  return a / b;\n}</update>"

const result = await morph.compact({
  input: chatHistory,
  query: "How do I validate JWT tokens?",
  compressionRatio: 0.5,
  preserveRecent: 3,
});

// result.output is the compressed text — pass it to your LLM
```

```python
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.morphllm.com/v1",
)

response = client.chat.completions.create(
    model="morph-compactor",
    messages=[{"role": "user", "content": chat_history}],
)

compressed = response.choices[0].message.content
```

```python
import requests

response = requests.post(
    "https://api.morphllm.com/v1/compact",
    headers={"Authorization": "Bearer YOUR_API_KEY"},

### Full Example: PR Preview Testing with Browser Automation

Source: https://docs.morphllm.com/sdk/components/automation/browser/github

Integrates GitHub SDK with Browser automation to perform end-to-end testing on pull request previews. This example finds a preview deployment, runs browser tests against it, and reports the results back to GitHub.

```typescript
import { MorphClient } from '@morphllm/morphsdk';

const morph = new MorphClient({ apiKey: process.env.MORPH_API_KEY });

async function testPRPreview(owner: string, repo: string, prNumber: number) {
  // 1. Get PR context
  const pr = await morph.github.pullRequests.get({
    owner, repo, number: prNumber
  });

  // 2. Create check run
  const checkRun = await morph.github.checkRuns.create({
    owner, repo,
    sha: pr.headSha,
    name: "Morph Preview Test",
    status: "in_progress",
    title: "Testing preview...",
    summary: "Running automated browser tests"
  });

  // 3. Find preview deployment
  const deployments = await morph.github.deployments.list({
    owner, repo, sha: pr.headSha
  });

  const preview = deployments.find(d =>
    d.state === "success" && d.url
  );

  if (!preview) {
    await morph.github.checkRuns.update({
      owner, repo,
      checkRunId: checkRun.id,
      conclusion: "skipped",
      title: "No preview found",
      summary: "No preview deployment available for this PR"
    });
    return;
  }

  // 4. Run browser test with PR context
  const task = await morph.browser.createTask({
    url: preview.url,
    diff: pr.diff,  // Agent uses diff to understand what to test
    task: "Test the changes in this PR",
    recordVideo: true
  });

  // 5. Wait for results
  const recording = await morph.browser.waitForRecording(task.recordingId);
  const webp = await recording.getWebp({ maxSizeMb: 5 });

  // 6. Update check run
  const success = !recording.error;
  await morph.github.checkRuns.update({
    owner, repo,
    checkRunId: checkRun.id,
    conclusion: success ? "success" : "failure",
    title: success ? "✅ Preview test passed" : "❌ Preview test failed",
    summary: recording.result || "Test completed"
  });

  // 7. Post comment with video
  await morph.github.comments.create({
    owner, repo, pr: prNumber,
    body: `## 🤖 Morph Preview Test

**Preview URL:** ${preview.url}

### Result
${recording.result || "Test completed"}

### Recording
