This guide covers extracting publicly accessible data. Always review a site's robots.txt and Terms of Service before scraping.

## TL;DR
Use AlterLab's Extract API with a JSON schema to get structured Best Buy product data. Define fields like title, price, and SKU in your schema, POST the URL and schema to `/v1/extract`, and receive validated JSON output: and receive validated JSON output—no HTML parsing needed.

## Why use Best Buy data?
Engineers integrate Best Buy data for:
- Training price prediction models with historical e-commerce trends
- Building competitive intelligence dashboards tracking SKU-level availability
- Enriching product catalogs for recommendation engines using public attribute data

## What data can you extract?
From publicly visible Best Buy product pages, you can extract:
- `title`: Product name (e.g., "Apple MacBook Pro 14-inch")
- `price`: Current selling price as string (avoids floating-point issues)
- `currency`: ISO currency code (e.g., "USD")
- `sku`: Best Buy's unique stock keeping unit
- `availability`: Text status like "In Stock" or "Coming Soon"
- `rating`: Average customer review score (e.g., "4.5")

These fields map cleanly to e-commerce data pipelines and ML feature stores.

## The extraction approach
Raw HTTP requests + HTML parsing fail on Best Buy due to:
- Dynamic content loaded via JavaScript after initial HTML
- Frequent DOM structure changes breaking CSS selectors
- Anti-bot measures requiring header rotation and proxy management

AlterLab's data API handles these challenges through:
- Automatic JavaScript rendering in headless browsers
- Schema-driven AI extraction (no selector maintenance)
- Built-in proxy rotation and rate limit compliance
- Validated JSON output matching your defined schema

## Quick start with AlterLab Extract API
[Getting started guide](/docs/quickstart/installation) shows installation. For Best Buy extraction:

```python title="extract_bestbuy-com.py" {5-12}
import alterlab

client = alterlab.Client("YOUR_API_KEY")

schema = {
  "type": "object",
  "properties": {
    "title": {
      "type": "string",
      "description": "Product title from Best Buy page"
    },
    "price": {
      "type": "string",
      "description": "Current price as displayed"
    },
    "currency": {
      "type": "string",
      "description": "3-letter currency code (USD, CAD, etc.)"
    },
    "sku": {
      "type": "string",
      "description": "Best Buy SKU identifier"
    },
    "availability": {
      "type": "string",
      "description": "Stock status text"
    },
    "rating": {
      "type": "string",
      "description": "Average rating (e.g., '4.2')"
    }
  }
}

result = client.extract(
    url="https://www.bestbuy.com/site/apple-macbook-pro-14-inch-space-gray/6438305.p",
    schema=schema,
)
print(result.data)
```

Equivalent cURL request:
```bash title="Terminal"
curl -X POST https://api.alterlab.io/v1/extract \
  -H "X-API-Key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://www.bestbuy.com/site/apple-macbook-pro-14-inch-space-gray/6438305.p",
    "schema": {
      "properties": {
        "title": {"type": "string"},
        "price": {"type": "string"},
        "currency": {"type": "string"},
        "sku": {"type": "string"},
        "availability": {"type": "string"},
        "rating": {"type": "string"}
      }
    }
  }'
```

- **99.2%** — Extraction Accuracy
- **1.4s** — Avg Response Time
- **100%** — Typed JSON Output

## Define your schema
The schema parameter drives AlterLab's AI extraction:
- Field names must match your desired output keys
- `description` helps the AI locate correct elements (optional but recommended)
- `type` enforces JSON schema validation (string/number/boolean/object/array)
- Output receives automatic type coercion (e.g., price strings stay strings to preserve precision)

AlterLab validates against your schema before returning data—failed validations include error details for debugging.

## Handle pagination and scale
For catalog-scale extraction:
1. **Batching**: Process 50-100 URLs per request using AlterLab's batch endpoint
2. **Rate limits**: Stay within your plan's requests/second (see [pricing](/pricing) for tiers)
3. **Async jobs**: For >10K URLs, use webhook notifications when batches complete

Example async batch job:
```python title="batch_extract.py" {8-15}
import alterlab
from alterlab import BatchJob

client = alterlab.Client("YOUR_API_KEY")

urls = [
    "https://www.bestbuy.com/site/apple-macbook-pro-14-inch-space-gray/6438305.p",
    "https://www.bestbuy.com/site/dell-xps-15/6402355.p",
    # ... 98 more URLs
]

job = BatchJob(
    client=client,
    urls=urls,
    schema=schema,  # Reuse schema from above
    webhook_url="https://yourdomain.com/webhook/alterlab",
    metadata={"source": "bestbuy_catalog"}
)

job.start()
print(f"Batch job {job.id} queued for processing")
```

1. **Define Schema** — 
2. **Call Extract API** — 
3. **Receive Typed JSON** —
