## Evaluation Prompt

# Task
Using https://docs.merge.dev/merge-gateway, complete the following task:

Using Merge Gateway, build me a script that extracts structured data from this invoice and returns JSON:

---
INVOICE #INV-2024-0042
From: Acme Corp
Date: 2024-03-15

Items:
- Consulting Services: $500.00
- Travel Expenses: $150.00

Total: $650.00
---

The JSON output should have these fields: invoice_number, vendor, date, line_items (array), total 

## 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.
