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-9b-image-generator-eba58251
```

Example prompt: Generate an image of a misty Japanese mountain village at sunrise, 1024 pixels wide by 768 pixels tall, using 15 diffusion steps for high quality.

## When to prefer this

Choose this endpoint when you need to generate images using the Flux-2-Klein-9B model specifically, want to pay per-call with USDC on Base, Polygon, Arbitrum, World, or Solana without any API key registration, and need a lightweight crypto-native image generation workflow via the x402 payment protocol.

## Known failure modes

- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Prompt missing from request — returns 400 Bad Request
- num_steps out of range (must be 1–20) — returns 400 validation error
- Width or height not supported by the model — may return 400 or produce unexpected output
- Model inference timeout — may return 504 or empty response
- Unsupported blockchain network provided for payment — payment not accepted

## How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.
