### Solving ReCaptchaV2 with Capsolver Python

Source: https://github.com/capsolver/capsolver-python/blob/main/README.md

This Python example demonstrates how to initialize the Capsolver library, optionally set the API key, and then solve a ReCaptchaV2 challenge using the ReCaptchaV2TaskProxyLess type. It requires the website key and URL.

```python
from pathlib import Path
import os
import base64
import capsolver

# tokenTask
print("api host",capsolver.api_base)
print("api key",capsolver.api_key)
# capsolver.api_key = "..."
solution = capsolver.solve({
        "type":"ReCaptchaV2TaskProxyLess",
        "websiteKey":"6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-",
        "websiteURL":"https://www.google.com/recaptcha/api2/demo"
    })

print(solution)
```

### Retrieving Capsolver Account Balance in Python

Source: https://github.com/capsolver/capsolver-python/blob/main/README.md

This Python example demonstrates how to check the current balance of your Capsolver account using the capsolver.balance() method, providing a quick way to monitor credits.

```python
import capsolver

# get current balance
balance = capsolver.balance()
# print the current balance
print(balance)
```

### Solving ImageToText CAPTCHA with Capsolver Python

Source: https://github.com/capsolver/capsolver-python/blob/main/README.md

This Python snippet illustrates how to solve an ImageToTextTask by reading an image file, encoding its content in base64, and sending it to Capsolver. It's configured for the 'queueit' module.

```python
from pathlib import Path
import os
import base64
import capsolver

# RecognitionTask
img_path = os.path.join(Path(__file__).resolve().parent,"queue-it.jpg")
with open(img_path,'rb') as f:
    solution = capsolver.solve({
        "type":"ImageToTextTask",
        "module":"queueit",
        "body":base64.b64encode(f.read()).decode("utf8")
    })
    print(solution)
```

### Setting Capsolver API Key as Environment Variable

Source: https://github.com/capsolver/capsolver-python/blob/main/README.md

This command sets the CAPSOLVER_API_KEY environment variable, which the Capsolver Python library automatically uses for authentication. This is a common way to manage sensitive credentials.

```bash
export CAPSOLVER_API_KEY='...'
```
