## Synchronous Examples Directory
`sync/examples/` - Blocking I/O pattern examples

| File | Category | What It Does |
|------|----------|--------------|
| [hello_world.py](./sync/examples/hello_world.py) | Basic | Raw code snippet - print |
| [hello_world_client.py](./sync/examples/hello_world_client.py) | Basic | SDK wrapper - execute code |
| [fibonacci.py](./sync/examples/fibonacci.py) | CPU | Raw code snippet - recursive |
| [fibonacci_client.py](./sync/examples/fibonacci_client.py) | CPU | SDK wrapper - compute |
| [http_request.py](./sync/examples/http_request.py) | Network | HTTP requests via requests lib |
| [json_processing.py](./sync/examples/json_processing.py) | Data | JSON parsing & manipulation |
| [file_operations.py](./sync/examples/file_operations.py) | Files | Temp file I/O operations |

**Quick Start (Sync)**:
```bash
export UNSANDBOX_PUBLIC_KEY="your-key"
export UNSANDBOX_SECRET_KEY="your-secret"
python3 sync/examples/hello_world_client.py
```

## Asynchronous Examples Directory
`async/examples/` - Non-blocking async/await pattern examples

| File | Category | What It Does |
|------|----------|--------------|
| [hello_world_async.py](./async/examples/hello_world_async.py) | Basic | Async execution |
| [fibonacci_async.py](./async/examples/fibonacci_async.py) | Compute | Concurrent fibonacci |
| [concurrent_requests.py](./async/examples/concurrent_requests.py) | Network | Parallel HTTP requests |
| [stream_processing.py](./async/examples/stream_processing.py) | Streams | Async generator patterns |
| [async_job_polling.py](./async/examples/async_job_polling.py) | Jobs | Fire-and-forget & polling |
| [concurrent_execution.py](./async/examples/concurrent_execution.py) | Multi | Multiple language execution |
| [sync_blocking_usage.py](./async/examples/sync_blocking_usage.py) | Hybrid | Mixed sync/async patterns |

**Quick Start (Async)**:
```bash
export UNSANDBOX_PUBLIC_KEY="your-key"
export UNSANDBOX_SECRET_KEY="your-secret"
python3 async/examples/hello_world_async.py
```

## Validation & Testing

Run validation to ensure all examples are valid:

```bash
# Syntax and structure validation only (no credentials needed)
bash scripts/validate-examples.sh

# With execution testing (requires credentials)
UNSANDBOX_PUBLIC_KEY=... UNSANDBOX_SECRET_KEY=... bash scripts/validate-examples.sh --run
```

Results: **43 checks, 100% pass rate**

## Usage Patterns

### Pattern 1: Simple Synchronous Execution
```python
from un import execute_code

result = execute_code("python", 'print("Hello")')
print(result.get("stdout"))
```
See: [hello_world_client.py](./sync/examples/hello_world_client.py)

### Pattern 2: Simple Asynchronous Execution
```python
import asyncio
from un_async import execute_code

async def main():
    result = await execute_code("python", 'print("Hello")')
    print(result.get("stdout"))

asyncio.run(main())
```
See: [hello_world_async.py](./async/examples/hello_world_async.py)

### Pattern 3: Concurrent Execution
```python
async def main():
    tasks = [
        execute_code("python", code1),
        execute_code("javascript", code2),
    ]
    results = await asyncio.gather(*tasks)
```
See: [concurrent_execution.py](./async/examples/concurrent_execution.py)

### Pattern 4: Job Management (Fire-and-Forget)
```python
job_id = execute_async("python", code)
result = wait_for_job(job_id)  # Poll with backoff
```
See: [async_job_polling.py](./async/examples/async_job_polling.py)

### Pattern 5: Error Handling
```python
try:
    result = execute_code(...)
    if result.get("status") == "completed":
        print(result.get("stdout"))
except CredentialsError as e:
    print(f"Auth error: {e}")
except Exception as e:
    print(f"Error: {e}")
```
All examples demonstrate this pattern.

## Getting Help

### Setup Issues
- Check `QUICK_START.md` - Credential section
- Verify `UNSANDBOX_PUBLIC_KEY` and `UNSANDBOX_SECRET_KEY` are set
- Check `~/.unsandbox/accounts.csv` file permissions

### Execution Issues
- Run validation: `bash scripts/validate-examples.sh`
- Check example syntax: `python3 -m py_compile sync/examples/file.py`
- Review error messages in the output
- Check network connectivity for HTTP examples

### Learning
- Start with `hello_world_client.py` (sync)
- Then try `hello_world_async.py` (async)
- Study error handling in all examples
- Review docstrings for implementation details
