# Yutori Python SDK & CLI

[![PyPI version](https://img.shields.io/pypi/v/yutori.svg)](https://pypi.org/project/yutori/)
[![Python 3.9+](https://img.shields.io/badge/python-3.9+-blue.svg)](https://www.python.org/downloads/)

The official Python library and CLI for the Yutori API.

Yutori provides APIs for building web agents that autonomously execute tasks on the web. The SDK offers both synchronous and asynchronous clients with full type annotations, plus a CLI for authentication and managing resources from the terminal.

## Documentation

- [API Reference](https://docs.yutori.com)
- [Platform Dashboard](https://platform.yutori.com)

## Installation

```bash
pip install yutori
```

## Getting Started

### Authentication

The easiest way to authenticate is to run this in your terminal:

**Terminal:**
```bash
yutori auth login
```

This opens your browser to log in with your Yutori account and saves an API key to `~/.yutori/config.json`. The SDK and CLI automatically use this saved key.

Alternatively, you can set the `YUTORI_API_KEY` environment variable, or pass the key directly:

```python
from yutori import YutoriClient

# Uses saved credentials from `yutori auth login`, or YUTORI_API_KEY env var
client = YutoriClient()

# Or pass explicitly
client = YutoriClient(api_key="yt-...")
```

API key resolution order: explicit parameter > `YUTORI_API_KEY` env var > `~/.yutori/config.json`.

## API Overview

The Yutori API provides four main capabilities:

| API          | Description                               | SDK Namespace     |
| ------------ | ----------------------------------------- | ----------------- |
| **n1**       | Pixels-to-actions LLM for browser control | `client.chat`     |
| **Browsing** | One-time browser automation tasks         | `client.browsing` |
| **Research** | Deep web research using 100+ tools        | `client.research` |
| **Scouting** | Continuous web monitoring on a schedule   | `client.scouts`   |

## n1 API

The n1 API is a pixels-to-actions LLM that processes screenshots and predicts browser actions (click, type, scroll, etc.). It follows the OpenAI Chat Completions interface:

```python
response = client.chat.completions.create(
    model="n1-latest",
    messages=[
        {
            "role": "user",
            "content": [
                {
                    "type": "text",
                    "text": "Describe the screenshot and search for Yutori."
                },
                {
                    "type": "image_url",
                    "image_url": {
                        "url": "https://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Google_homepage_%28as_of_January_2024%29.jpg/1280px-Google_homepage_%28as_of_January_2024%29.jpg"
                    }
                }
            ]
        }
    ]
)

# Get the thoughts
message = response.choices[0].message
print(message.content)

# Get the tool calls, such as browser interaction actions
if message.tool_calls:
    for tool_call in message.tool_calls:
        print(f"Action: {tool_call.function.name}")
        print(f"Arguments: {tool_call.function.arguments}")
```

If you don't want to manage your own browser infrastructure, use the Browsing API which calls n1 on a cloud browser.

## Browsing API

Run one-time browser automation tasks. An AI agent operates a cloud browser to complete your task.

```python
# Create a browsing task
task = client.browsing.create(
    task="Give me a list of all employees (names and titles) of Yutori.",
    start_url="https://yutori.com",
)

# Poll for completion
import time
while True:
    result = client.browsing.get(task["task_id"])
    if result["status"] in ("succeeded", "failed"):
        break
    time.sleep(5)

print(result)
```

### Structured Output with Webhooks

You can define the output structure using a JSON schema dict or a Pydantic BaseModel class (Pydantic is optional):

```python
from pydantic import BaseModel  # optional dependency

class Employee(BaseModel):
    name: str
    title: str

task = client.browsing.create(
    task="Give me a list of all employees (names and titles) of Yutori.",
    start_url="https://yutori.com",
    max_steps=75,
    webhook_url="https://example.com/webhook",
    output_schema=Employee,  # auto-converted to JSON schema
)
```

<summary>Using a JSON schema dict instead</summary>

```python
task = client.browsing.create(
    task="Give me a list of all employees (names and titles) of Yutori.",
    start_url="https://yutori.com",
    max_steps=75,
    webhook_url="https://example.com/webhook",
    output_schema={
        "type": "array",
        "items": {
            "type": "object",
            "properties": {
                "name": {"type": "string"},
                "title": {"type": "string"}
            }
        }
    }
)
```

## Research API

Perform deep web research using 100+ MCP tools including search engines, APIs, and data sources.

```python
task = client.research.create(
    query="What are the latest developments in quantum computing from the past week?",
    user_timezone="America/Los_Angeles",
)

# Poll for results
import time
while True:
    result = client.research.get(task["task_id"])
    if result["status"] in ("succeeded", "failed"):
        break
    time.sleep(5)

print(result)
```

### Structured Output

```python
from pydantic import BaseModel  # optional dependency

class Finding(BaseModel):
    title: str
    summary: str
    source_url: str

task = client.research.create(
    query="What are the latest developments in quantum computing?",
    user_timezone="America/Los_Angeles",
    webhook_url="https://example.com/webhook",
    output_schema=Finding,  # auto-converted to JSON schema
)
```

                "source_url": {"type": "string"}
            }
        }
    }
)
```

## Scouting API

Scouts run on a configurable schedule to monitor the web and send notifications when relevant updates occur.

```python
from yutori import YutoriClient

client = YutoriClient(api_key="yt-...")

# Create a scout that monitors for updates
scout = client.scouts.create(
    query="Tell me about the latest news, product updates, and announcements about Yutori AI",
)
print(f"Created scout: {scout['id']}")

# List all active scouts
scouts = client.scouts.list(status="active")

# Get a specific scout
scout = client.scouts.get("scout_abc123")

# Pause a scout
client.scouts.update("scout_abc123", status="paused")

# Resume a scout
client.scouts.update("scout_abc123", status="active")

# Archive a scout
client.scouts.update("scout_abc123", status="done")

# Get scout updates
updates = client.scouts.get_updates("scout_abc123", limit=20)

# Delete a scout
client.scouts.delete("scout_abc123")
```

### Structured Output with Webhooks

```python
from pydantic import BaseModel  # optional dependency

class NewsItem(BaseModel):
    headline: str
    summary: str
    source_url: str

scout = client.scouts.create(
    query="Tell me about the latest news, product updates, and announcements about Yutori AI",
    output_interval=86400,  # Daily
    user_timezone="America/Los_Angeles",
    skip_email=True,
    webhook_url="https://example.com/webhook",
    output_schema=NewsItem,  # auto-converted to JSON schema
)
```

<details>
<summary>Using a JSON schema dict instead</summary>

```python
scout = client.scouts.create(
    query="Tell me about the latest news, product updates, and announcements about Yutori AI",
    output_interval=86400,  # Daily
    user_timezone="America/Los_Angeles",
    skip_email=True,
    webhook_url="https://example.com/webhook",
    output_schema={
        "type": "array",
        "items": {
            "type": "object",
            "properties": {
                "headline": {"type": "string"},
                "summary": {"type": "string"},
                "source_url": {"type": "string"}
            }
        }
    }
)
```

</details>

## Async Usage

The SDK provides an async client with the same interface:

```python
import asyncio
from yutori import AsyncYutoriClient

async def main():
    async with AsyncYutoriClient(api_key="yt-...") as client:
        # All methods are async
        usage = await client.get_usage()
        print(usage)

        scouts = await client.scouts.list()
        print(scouts)

        scout = await client.scouts.create(
            query="Monitor https://example.com for updates",
            output_interval=3600,
        )
        print(scout)

asyncio.run(main())
```

## Error Handling

The SDK raises typed exceptions for API errors:

```python
from yutori import YutoriClient, APIError, AuthenticationError

try:
    client = YutoriClient(api_key="invalid-key")
    client.get_usage()
except AuthenticationError as e:
    print(f"Invalid API key: {e}")
except APIError as e:
    print(f"API error (status {e.status_code}): {e.message}")
```

### Exception Types

| Exception             | Status Code | Description                        |
| --------------------- | ----------- | ---------------------------------- |
| `AuthenticationError` | 401, 403    | Invalid or missing API key         |
| `APIError`            | 4xx, 5xx    | General API error with status code |

## Configuration

```python
from yutori import YutoriClient

client = YutoriClient(
    api_key="yt-...",                          # Or: yutori auth login / YUTORI_API_KEY
    base_url="https://api.yutori.com/v1",      # Default
    timeout=30.0,                               # Request timeout in seconds
)
```

## CLI

The CLI provides commands for authentication and managing Yutori resources from the terminal.

```bash
# Version
yutori --version

# Authentication
yutori auth login       # Log in via browser
yutori auth status      # Show current auth status
yutori auth logout      # Remove saved credentials

# Scouts
yutori scouts list                          # List your scouts
yutori scouts get SCOUT_ID                  # Get scout details
yutori scouts create -q "monitor for news"  # Create a scout
yutori scouts delete SCOUT_ID               # Delete a scout

# Browsing
yutori browse run "extract all prices" https://example.com/products
yutori browse run "log in and continue" https://example.com/login --require-auth
yutori browse get TASK_ID

# Research
yutori research run "latest developments in quantum computing"
yutori research get TASK_ID

# Usage
yutori usage            # Show API usage statistics
```
