Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-generation-via-locus-x402-2cc89da2 -d '<json body>'
```

Example prompt: Use Grok to generate a single 2k resolution 16:9 landscape image of a futuristic city at sunset with neon lights, using the grok-imagine-image-quality model, and return the image URL.

## When to prefer this

Choose this endpoint when you need AI image generation powered by xAI's Grok models specifically, want micropayment-based pay-per-call pricing via x402 (no subscription required), need control over resolution (1k/2k), aspect ratio, and output format (URL vs base64), or are building an agent pipeline that integrates Coinbase-compatible x402 payments natively.

## Known failure modes

- Invalid or missing prompt — returns error, no image generated
- Unsupported model ID — must be 'grok-imagine-image' or 'grok-imagine-image-quality'
- Unsupported resolution value — only '1k' or '2k' accepted
- Invalid aspect ratio string — must match accepted formats like '1:1', '16:9', etc.
- Payment failure — x402 payment not authorized or USDC balance insufficient
- Request timeout — image generation exceeds processing window
- n exceeds allowed batch limit — too many images requested at once

## How this service works

Locus public pay-per-use API

## Output

Returns a JSON object containing a `data` field with the generated image (as a URL or base64-encoded string depending on response_format), a `payment` object confirming 0.001 USDC was settled, a `request` object with a unique request ID and status URL for tracking, and a `success` boolean.
