# Python SDK

> Avala Python SDK-க்கான முழு வழிகாட்டி

<Info>The Python SDK requires **Python 3.9+**.</Info>

## Installation

```bash theme={null}
pip install avala
```

## Quick Start

```python theme={null}
from avala import Client

client = Client(api_key="your-api-key")

# List all datasets
datasets = client.datasets.list()
for dataset in datasets:
    print(dataset.name, dataset.uid)
```

## Create an Account

The `signup` function creates a new Avala account and returns an API key. It does not require authentication.

```python theme={null}
from avala import signup

result = signup(
    email="dev@acme.com",
    password="SecurePass123!",
    first_name="Jane",       # optional
    last_name="Doe",         # optional
)

print(f"User: {result.user.email}")
print(f"API Key: {result.api_key}")
```

An async variant is also available:

```python theme={null}
from avala import async_signup

result = await async_signup(email="dev@acme.com", password="SecurePass123!")
```

## Authentication

The SDK authenticates using your Avala API key, which is sent via the `X-Avala-Api-Key` header on every request.

You can provide the key directly or let the SDK read it from the environment.

**Option 1: Pass the key directly**

```python theme={null}
from avala import Client

client = Client(api_key="your-api-key")
```

**Option 2: Use an environment variable**

```bash theme={null}
export AVALA_API_KEY="your-api-key"
```

```python theme={null}
from avala import Client

# Automatically reads AVALA_API_KEY from the environment
client = Client()
```

## Async Support

The SDK ships with a fully async client built on top of `httpx`. Use `AsyncClient` for non-blocking I/O in async applications.

```python theme={null}
import asyncio
from avala import AsyncClient

async def main():
    client = AsyncClient(api_key="your-api-key")

    datasets = await client.datasets.list()
    for dataset in datasets:
        print(dataset.name)

    # Always close the client when done, or use it as a context manager
    await client.close()

asyncio.run(main())
```

**Using the async context manager:**

```python theme={null}
import asyncio
from avala import AsyncClient

async def main():
    async with AsyncClient() as client:
        datasets = await client.datasets.list()
        for dataset in datasets:
            print(dataset.name)

asyncio.run(main())
```

## Working with Datasets

<Note>
  The Python SDK is currently **read-only for datasets** — you can list, retrieve, and browse items but not create or delete datasets. Use the [REST API](/docs/sdks/rest-api#file-uploads) for uploads and mutations.
</Note>

### List Datasets

```python theme={null}
datasets = client.datasets.list()

for dataset in datasets:
    print(f"{dataset.name} ({dataset.uid})")
    print(f"  Items: {dataset.item_count}")
    print(f"  Created: {dataset.created_at}")
```

### Get a Dataset

```python theme={null}
dataset = client.datasets.get("550e8400-e29b-41d4-a716-446655440000")

print(dataset.name)
print(dataset.slug)
print(dataset.item_count)
```

## Working with Projects

### List Projects

```python theme={null}
projects = client.projects.list()

for project in projects:
    print(f"{project.name} ({project.uid})")
    print(f"  Status: {project.status}")
    print(f"  Created: {project.created_at}")
```

### Get a Project

```python theme={null}
project = client.projects.get("770a9600-a40d-63f6-c938-668877660000")

print(project.name)
print(project.status)
```

## Working with Tasks

### List Tasks

```python theme={null}
tasks = client.tasks.list(project="770a9600-a40d-63f6-c938-668877660000", status="pending")

for task in tasks:
    print(f"{task.uid} — {task.name} ({task.status})")
```

### Get a Task

```python theme={null}
task = client.tasks.get("990c1800-b62f-85a8-e150-880099880000")

print(task.name)
print(task.status)
```

## Working with Exports

<Note>
  The Python SDK supports full CRUD operations for agents, webhooks, storage configurations, inference providers, quality targets, consensus config, and organizations. Datasets and projects are currently read-only — use the [REST API](/docs/sdks/rest-api) for mutations on those resources.
</Note>

### Create an Export

```python theme={null}
export = client.exports.create(project="770a9600-a40d-63f6-c938-668877660000")

print(f"Export started: {export.uid}")
print(f"Status: {export.status}")
```

### Poll for Completion

```python theme={null}
import time

export = client.exports.create(project="770a9600-a40d-63f6-c938-668877660000")

while export.status != "completed":
    time.sleep(2)
    export = client.exports.get(export.uid)
    print(f"Status: {export.status}")

print(f"Download: {export.download_url}")
```

## Working with Organizations

### List Organizations

```python theme={null}
orgs = client.organizations.list()
for org in orgs:
    print(f"{org.name} ({org.slug})")
```

### Create an Organization

```python theme={null}
org = client.organizations.create(name="My Team", visibility="private", industry="technology")
print(f"Created: {org.name} ({org.uid})")
```

### Manage Members

```python theme={null}
members = client.organizations.list_members("my-team")
for member in members:
    print(f"{member.full_name} - {member.role}")
```

## Working with Slices

### List Slices

```python theme={null}
slices = client.slices.list("my-org")
for s in slices:
    print(f"{s.name}: {s.item_count} items")
```

## Browsing Dataset Items

### List Items in a Dataset

```python theme={null}
items = client.datasets.list_items("my-org", "my-dataset")
for item in items:
    print(f"{item.uid}: {item.key}")
```

### List Sequences

```python theme={null}
sequences = client.datasets.list_sequences("my-org", "my-dataset")
for seq in sequences:
    print(f"{seq.uid}: {seq.key} ({seq.number_of_frames} frames)")
```

## Type Hints

The SDK is fully typed. All response objects are Pydantic models with complete type annotations, giving you autocomplete and type checking out of the box.

```python theme={null}
from avala.types import Dataset, Project, Export, Task

def process_dataset(dataset: Dataset) -> None:
    print(dataset.name)        # str
    print(dataset.uid)         # str
    print(dataset.item_count)  # int
    print(dataset.created_at)  # Optional[datetime]

def process_task(task: Task) -> None:
    print(task.uid)            # str
    print(task.name)           # Optional[str]
    print(task.status)         # Optional[str]
    print(task.project)        # Optional[str]
```

## Error Handling

The SDK raises typed exceptions so you can handle different failure modes precisely.

```python theme={null}
from avala import Client
from avala.errors import (
    AvalaError,
    NotFoundError,
    RateLimitError,
    ValidationError,
)

client = Client()

try:
    dataset = client.datasets.get("nonexistent")
except NotFoundError as e:
    print(f"Dataset not found: {e.message}")
except RateLimitError as e:
    print(f"Rate limited. Retry after {e.retry_after} seconds.")
except ValidationError as e:
    print(f"Invalid request: {e.message}")
    for detail in e.details:
        print(f"  - {detail}")
except AvalaError as e:
    # Catch-all for any other Avala API error
    print(f"API error ({e.status_code}): {e.message}")
```

| Exception             | Description                                                                                                   |
| --------------------- | ------------------------------------------------------------------------------------------------------------- |
| `AvalaError`          | Base exception for all Avala API errors.                                                                      |
| `AuthenticationError` | Invalid or missing API key (HTTP 401).                                                                        |
| `NotFoundError`       | The requested resource does not exist (HTTP 404).                                                             |
| `RateLimitError`      | You have exceeded the API rate limit (HTTP 429). Includes a `retry_after` attribute.                          |
| `ValidationError`     | The request payload failed validation (HTTP 400/422). Includes a `details` attribute with field-level errors. |
| `ServerError`         | The server returned an internal error (HTTP 5xx).                                                             |

## Pagination

List methods return a `CursorPage` object. You can iterate through items directly or control pagination manually.

```python theme={null}
# Iterate through items on the current page
for dataset in client.datasets.list():
    print(dataset.name)

# Manual pagination — control page size and access cursor
page = client.datasets.list(limit=10)
for dataset in page.items:
    print(dataset.name)

# Fetch the next page
if page.has_more:
    next_page = client.datasets.list(limit=10, cursor=page.next_cursor)
```

## Fleet Management

<Info>
  Fleet Management is in preview. APIs described here may change.
</Info>

The `fleet` namespace provides access to device registry, recordings, events, rules, and alerts.

```python theme={null}
# List online devices
devices = client.fleet.devices.list(status="online")

# Create a timeline event on a recording
event = client.fleet.events.create(
    recording_id="rec_abc123",
    timestamp="2026-01-15T10:30:00Z",
    type="anomaly",
    label="Gripper force spike",
    metadata={"force_n": 45.2}
)

# Create a recording rule
rule = client.fleet.rules.create(
    name="High Latency Alert",
    condition={"type": "threshold", "topic": "/diagnostics/latency", "field": "data.value", "operator": "gt", "value": 100},
    actions=[{"type": "tag", "value": "high-latency"}, {"type": "notify", "channel_id": "ch_your_channel_id"}]
)
```

See the [Fleet Dashboard](/docs/visualization/fleet/fleet-dashboard) guide for complete examples.

## Configuration

You can customize the client behavior at initialization time.

```python theme={null}
from avala import Client

client = Client(
    api_key="your-api-key",
    base_url="https://api.avala.ai/api/v1",  # Default
    timeout=60,        # Request timeout in seconds (default: 30)
    max_retries=3,     # Number of retries on transient errors (default: 2)
)
```

| Parameter     | Type    | Default                       | Description                                                        |
