## Evaluation Prompt

````text

# Task
Using https://docs.lemonsqueezy.com, complete the following task:

Using LemonSqueezy, build me a payment link for a $29/month "Pro Plan" subscription and print the URL

The script should:
1. Create a product/price if needed
2. Create a **payment link** (NOT a checkout session — payment links don't expire)
3. Print the payment link URL to stdout

Important: Use payment links, not checkout sessions. Checkout sessions expire after 24 hours, but payment links are permanent and reusable. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
