## 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 image-withzero-xyz-xai-grok-imagine-image-generation-5c994abc -d '<json body>'
```

## When to prefer this

Choose this endpoint when you specifically want xAI's Grok Imagine model for image generation, particularly if you prefer Grok's visual style or are comparing outputs across providers. Use it over the OpenAI or Google alternatives when Grok's aesthetic or model provenance matters to the use case.
