Examples

Complete Workflow

from xase import XaseClient

def main():
    client = XaseClient(api_key='your-api-key')
    
    # 1. Create a dataset
    dataset = client.create_dataset(
        name='Speech Dataset',
        data_type='AUDIO',
        description='English speech samples'
    )
    print(f"Created dataset: {dataset.id}")
    
    # 2. Create access policy
    policy = client.create_policy(
        name='Research Access',
        dataset_id=dataset.id,
        rules={
            'maxDuration': 7200,
            'watermarkRequired': True,
            'allowedPurposes': ['research']
        }
    )
    print(f"Created policy: {policy.id}")
    
    # 3. Create lease
    lease = client.create_lease(
        dataset_id=dataset.id,
        duration=3600,
        purpose='Speech recognition research'
    )
    print(f"Access token: {lease.accessToken}")
    
    # 4. Record usage
    client.record_usage(
        lease_id=lease.id,
        bytes_transferred=5000000,
        records_accessed=500
    )
    
    # 5. Get usage stats
    usage = client.get_usage()
    total_bytes = sum(u.bytesTransferred for u in usage)
    print(f"Total bytes transferred: {total_bytes}")

if __name__ == '__main__':
    main()

Batch Operations

from xase import XaseClient

client = XaseClient(api_key='your-api-key')

# Create multiple datasets
datasets = []
for i in range(5):
    dataset = client.create_dataset(
        name=f'Dataset {i+1}',
        data_type='AUDIO',
        description=f'Dataset number {i+1}'
    )
    datasets.append(dataset)
    print(f"Created: {dataset.name}")

# Create leases for all datasets
leases = []
for dataset in datasets:
    lease = client.create_lease(
        dataset_id=dataset.id,
        duration=3600
    )
    leases.append(lease)
    print(f"Lease created for {dataset.name}")

Error Recovery

from xase import XaseClient
from xase.exceptions import XaseAPIError
import time

client = XaseClient(api_key='your-api-key')

def create_lease_with_retry(dataset_id, max_retries=3):
    for attempt in range(max_retries):
        try:
            return client.create_lease(dataset_id=dataset_id)
        except XaseAPIError as e:
            if e.status_code == 429:  # Rate limit
                wait_time = 2 ** attempt  # Exponential backoff
                print(f"Rate limited, waiting {wait_time}s...")
                time.sleep(wait_time)
            else:
                raise
    raise Exception("Max retries exceeded")

lease = create_lease_with_retry('dataset-id')
