## 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-dev-image-generation-a464dc82
```

Example prompt: Generate an image of a futuristic city at sunset with neon lights reflecting on wet streets, at 1024x768 pixels and 20 diffusion steps for maximum quality.

## When to prefer this

Choose this endpoint when you need text-to-image generation using the Flux-2-Dev model specifically, want to pay per-call with USDC on Base, Polygon, Arbitrum, World, or Solana without managing API keys or subscriptions, and value the x402 micropayment protocol for permissionless access.

## Known failure modes

- Payment failure or insufficient USDC balance returns 402 Payment Required
- Invalid or missing prompt returns 400 Bad Request
- num_steps out of range (must be 1-20) returns validation error
- Unsupported or invalid width/height values may cause model error
- Network timeout if diffusion takes too long at high step counts
- Blockchain network congestion may delay payment confirmation

## How this service works
