## Evaluation Prompt

````text

# Task
Using https://[REDACTED:TENANT].speechify.ai/tts/api-reference/introduction, complete the following task:

Using Speechify, build me a Python script that converts text to speech:

1. Follow the Speechify documentation to authenticate and choose the simplest text-to-speech API path
2. Convert this text to speech:
   "Your order has been shipped and will arrive by Friday."
3. Save the audio as output.mp3. If only WAV output is supported, save it as output.wav instead
4. Print a confirmation message with the filename when the file is saved

Use documented Speechify APIs only; do not generate fake or placeholder audio. 

## 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.
