## 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-9b-image-generator-25f6bee3
```

Example prompt: Generate an image of a neon-lit cyberpunk city street at night with rain reflections on the pavement — make it 1024 pixels wide and 768 pixels tall, using 15 diffusion steps for high quality.

## When to prefer this

Choose this endpoint when you need on-demand text-to-image generation without managing API keys, using a crypto micropayment (USDC on Base, Polygon, Arbitrum, World, or Solana) via the x402 protocol. Ideal for autonomous agents that hold crypto wallets and need to generate images programmatically at $0.085 per call. Prefer this over OpenAI/Stability API wrappers when avoiding centralized API key management or when operating in a web3-native payment context.

## Known failure modes

- Insufficient USDC balance or payment failure — HTTP 402 Payment Required
- Invalid prompt (empty string) — request rejected or blank/garbled output
- num_steps out of range (must be 1–20) — validation error
- Model timeout or overload on Cloudflare Workers — HTTP 5xx error
- Unsupported width/height values — model may ignore or clip dimensions
- Network error reaching workers.dev host — connection timeout

## How this service works

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

## Output
