## Quick Start

First, you'll need an API key from [UPC Database](https://upcdatabase.org/):

1. Create a free account at https://upcdatabase.org/signup
2. Register your application at https://upcdatabase.org/apikeys to get your API key

Then use the library:

```python
from upcdatabase import UPCDatabase

# Initialize the client
client = UPCDatabase(api_key="your_api_key_here")

# Look up a product by UPC
product = client.lookup("036000291204")
print(product["name"])
print(product["price"])
```

## Usage Examples

### Product Lookup

```python
from upcdatabase import UPCDatabase

client = UPCDatabase(api_key="your_api_key")

# Look up by UPC code
product = client.lookup("036000291204")
print(f"Product: {product['name']}")
print(f"Manufacturer: {product['manufacturer']}")
print(f"Price: ${product['price']}")
print(f"Image: {product['image']}")
```

### Search Products

```python
# Search for products
results = client.search("coca cola", limit=20)
for item in results.get("items", []):
    print(f"{item['name']} - {item['upc']}")
```

### Get Currency Data

```python
# Latest currency rates
rates = client.get_latest_currency()
print(rates)

# Historical rates
history = client.get_currency_history("2025-01-15")
print(history)

# Available symbols
symbols = client.get_currency_symbols()
print(symbols)
```

### Get Bitcoin Data

```python
# Latest Bitcoin rate
btc = client.get_latest_bitcoin()
print(f"BTC: ${btc['price']}")

# Historical Bitcoin rate
btc_history = client.get_bitcoin_history("2025-01-15")
print(btc_history)
```

### Generate QR Codes

```python
# Generate a QR code
qr = client.generate_qr("https://example.com")
print(qr)
```

### Get Account Information

```python
# Check account and API usage
account = client.get_account_info()
print(f"Requests remaining: {account['requests_remaining']}")
```

## Using as a Context Manager

```python
from upcdatabase import UPCDatabase

# The session will be automatically closed when exiting the block
with UPCDatabase(api_key="your_api_key") as client:
    product = client.lookup("036000291204")
    print(product["name"])
```

## Error Handling

```python
from upcdatabase import UPCDatabase, UPCDatabaseError

client = UPCDatabase(api_key="your_api_key")

try:
    product = client.lookup("invalid_code")
except UPCDatabaseError as e:
    print(f"Error: {e}")
except Exception as e:
    print(f"Unexpected error: {e}")
```
