## 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 ai-rook-image-generation-flux-2-klein-1b1b832a
```

Example prompt: Generate an image of a futuristic city skyline at sunset with neon lights reflecting off wet streets — pay for it using USDC on Base via AI Rook and give me the result as a PNG.

## When to prefer this

Choose this endpoint when you need a quick, no-signup AI image generation call paid micropayment-style in USDC on Base mainnet via x402, especially in agentic workflows where acquiring API keys is impractical. FLUX.2-klein is optimized for speed; prefer this over heavier models when turnaround time matters and you want a fixed $0.15/call cost with on-chain accountability.

## Known failure modes

- Insufficient USDC balance on Base mainnet — payment rejected, image not generated
- Prompt violates content policy — generation refused
- Model overload or timeout — elapsed_ms exceeds threshold and no image returned
- Malformed or missing prompt parameter — API returns error
- Network or x402 payment protocol failure — transaction not confirmed
