## How to call it through Zero

```sh
zero fetch --capability questflow-9b66c518 -d '<json body>'
```

Example prompt: Take this image of a woman in a red dress and change her outfit to a blue suit while keeping the background and her face exactly the same.

## When to prefer this

Choose this endpoint when you need text-prompt-driven image editing with strong character consistency and scene preservation — particularly for portrait or character-focused edits. Prefer it over generic image generation endpoints when the goal is to modify an existing image rather than generate from scratch, and when maintaining identity or background coherence is critical.

## Known failure modes

- Invalid or missing image input returns an error
- Text prompt too vague or contradictory may produce unexpected edits
- Payment of $0.5 USDC not provided or declined results in 402 response
- Model may fail to preserve scene elements if prompt conflicts with image content
- Unsupported image format or oversized image may cause rejection
