## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability flux-2-pro-high-quality-image-generation-with-reference-images-d6a7f74a -d '<json body>'
```

Example prompt: Generate a high-quality cinematic landscape image of a misty mountain valley at sunrise in 16:9 aspect ratio, using these two reference images for color palette and mood: [https://example.com/ref1.jpg, https://example.com/ref2.jpg].

## When to prefer this

Choose this endpoint when you need high-quality image generation with strong style or composition guidance from multiple reference images (up to eight). It is superior to basic text-to-image endpoints when brand consistency, style matching, or multi-reference composition is important. Prefer this over simpler models (e.g. Nano Banana, Grok Imagine) when output fidelity and detail are critical.

## Known failure modes

- Invalid or inaccessible reference image URLs return an error
- Prompt too vague or empty results in a generic or failed generation
- Unsupported aspect ratio value causes a validation error
- Payment not processed (x402 protocol failure) blocks the request
- Rate limiting or quota exceeded returns a 429 error
- Model timeout on complex prompts may return a 504 or partial response
