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 gedx402-flux-2-klein-4b-image-generator-dda475b1
```

Example prompt: Generate an image of a misty mountain lake at sunrise with golden reflections on the water, 1024 pixels wide and 768 pixels tall, using 15 diffusion steps for good quality.

## When to prefer this

Choose this endpoint when you need AI image generation without setting up API keys or accounts — ideal for agents that can pay with USDC on Base, Polygon, Arbitrum, World, or Solana. Best suited for single image generation tasks using the Flux-2 Klein 4B model specifically, with control over resolution and quality/speed tradeoff via diffusion steps.

## Known failure modes

- Invalid or missing prompt results in a bad request error
- Width or height values unsupported by the model may be silently clamped or cause an error
- num_steps outside range 1-20 will be rejected as invalid
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Network timeout if the diffusion model takes too long to generate
- Unsupported blockchain network for payment causes transaction failure

## How this service works
