## 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 grok-image-edit-via-locus-x402-a8463db2 -d '<json body>'
```

Example prompt: Take this product photo at https://example.com/shoe.jpg and add a grassy outdoor background to it — use the grok-imagine-image model at 1k resolution and give me back the URL of the edited image.

## When to prefer this

Choose this endpoint when you need to modify or transform an existing image using a natural-language prompt, rather than generating an image from scratch. It is backed by xAI's Grok image models and billed per-call in USDC via x402, making it suitable for agents that need pay-as-you-go image editing without subscription overhead. Prefer the 'grok-imagine-image-quality' model and '2k' resolution when output fidelity matters, and the default 'grok-imagine-image' at '1k' for faster, cheaper edits.

## Known failure modes

- Invalid or inaccessible source image URL returns an error
- Unsupported model ID causes a validation failure
- Insufficient USDC balance or failed x402 payment results in 402 Payment Required
- Prompt too vague or empty may produce unexpected edits or an error
- Resolution value outside '1k'/'2k' enum causes a bad request
- Base64 image data that is malformed or too large may be rejected

## How this service works

xAI models — chat, web/X search, code execution, image generation/editing, and text-to-speech.

## Output

A JSON object containing a 'data' field with the edited image (as a URL or base64 string depending on response_format), a 'payment' object confirming 0.001 USDC was settled, a 'request' object with a unique ID and status URL for polling, and a 'success' boolean.
