## How to call it through Zero

```sh
zero fetch --capability questflow-4fb29e97 -d '<json body>'
```

Example prompt: Can you transform this photo to have warm, golden hour lighting? Here's the image: https://example.com/my-photo.jpg — just describe the effect in plain English and apply it.

## When to prefer this

Use this endpoint when a user wants to edit or stylize a photo using conversational, plain-English instructions rather than manual editing tools. Ideal for non-technical users who want AI-driven photo transformations like lighting adjustments, style changes, or aesthetic modifications without needing Photoshop or design skills.

## Known failure modes

- Missing X-PAYMENT header returns 402 with payment details
- Invalid or inaccessible image URL causes processing failure
