- Price: $0.1/call
- Payment: x402
- Status: down

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 api-imgzen-dev-f71268c2 -d '<json body>'
```

Example prompt: Generate a natural-style image of a serene mountain lake at sunrise with mist over the water, in 3:2 aspect ratio, high quality, PNG format with an opaque background.

## When to prefer this

Choose this endpoint when you need OpenAI's GPT Image 1.5 model specifically at $0.10/image with x402 crypto micropayment support, want optional image editing from up to 5 reference images, need transparent background support, or want a balance between OpenAI quality and cost (vs GPT Image 1 at the same price but older model). Prefer over sibling Gemini endpoints when OpenAI's rendering style is preferred over Google's.

## Known failure modes

- Invalid prompt or missing prompt field returns 400 error
- Reference image URLs that are inaccessible or malformed cause image editing to fail
- Payment failure via x402 (insufficient USDC balance or wallet misconfiguration) blocks generation
- Unsupported enum values for style, quality, background, aspect_ratio, or output_format return validation error
- More than 5 reference images provided exceeds maxItems constraint
- Timeout if generation exceeds server limits (generation can take ~26 seconds)
