+title: Code Examples
+description: Practical examples for building on AITBC
+---
+
+# Code Examples
+
+This section provides practical examples for common tasks on the AITBC platform.
+
+## Python Examples
+
+### Basic Job Submission
+```python
+from aitbc import AITBCClient
+
+client = AITBCClient(api_key="your_key")
+
+job = client.jobs.create({
+    "name": "image-classification",
+    "type": "ai-inference",
+    "model": {
+        "type": "python",
+        "entrypoint": "model.py",
+        "requirements": ["torch", "pillow"]
+    }
+})
+
+result = client.jobs.wait_for_completion(job["job_id"])
+```
+
+### Batch Job Processing
+```python
+import asyncio
+from aitbc import AsyncAITBCClient
+
+async def process_images(image_paths):
+    client = AsyncAITBCClient(api_key="your_key")
+    
+    tasks = []
+    for path in image_paths:
+        job = await client.jobs.create({
+            "name": f"process-{path}",
+            "type": "image-analysis"
+        })
+        tasks.append(client.jobs.wait_for_completion(job["job_id"]))
+    
+    results = await asyncio.gather(*tasks)
+    return results
+```
+
+## JavaScript Examples
+
+### React Component
+```jsx
+import React, { useState, useEffect } from 'react';
+import { AITBCClient } from '@aitbc/client';
+
+function JobList() {
+    const [jobs, setJobs] = useState([]);
+    const client = new AITBCClient({ apiKey: 'your_key' });
+    
+    useEffect(() => {
+        async function fetchJobs() {
+            const jobList = await client.jobs.list();
+            setJobs(jobList);
+        }
+        fetchJobs();
+    }, []);
+    
+    return (
+        <div>
+            {jobs.map(job => (
+                <div key={job.jobId}>
+                    <h3>{job.name}</h3>
+                    <p>Status: {job.status}</p>
+                </div>
+            ))}
+        </div>
+    );
+}
+```
+
+### WebSocket Integration
+```javascript
+const client = new AITBCClient({ apiKey: 'your_key' });
+const ws = client.websocket.connect();
+
+ws.on('jobUpdate', (data) => {
+    console.log(`Job ${data.jobId} updated to ${data.status}`);
+});
+
+ws.subscribe('jobs');
+ws.start();
+```
+
+## CLI Examples
+
+### Job Management
+```bash
+# Create job from file
+aitbc job create job.yaml
+
+# List all jobs
+aitbc job list --status running
+
+# Monitor job progress
+aitbc job watch <job_id>
+
+# Download results
+aitbc job download <job_id> --output ./results/
+```
+
+### Marketplace Operations
+```bash
+# List available offers
+aitbc marketplace list --type image-classification
+
+# Create offer as miner
+aitbc marketplace create-offer offer.yaml
+
+# Accept offer
+aitbc marketplace accept <offer_id> --job-id <job_id>
+```
