## 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 glianaai-flux-2-pro-preview-pay-per-call-image-generation-0d508fe9
```

Example prompt: Generate a photorealistic image of a misty Japanese forest at dawn with soft golden light filtering through ancient cedar trees — use Flux 2 Pro Preview and pay in USDC.

## When to prefer this

Choose this endpoint when you need to generate images using the Flux 2 Pro Preview model specifically, want pay-per-call billing in USDC without any signup or API key management, and are operating an autonomous AI agent that can handle x402 micropayment flows on Base, Solana, or Tempo. Prefer this over traditional API-key services when building agent workflows that need trustless, on-chain payment settlement.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Invalid or empty prompt returns a 400 validation error
- Model-specific input format mismatch (consult GET /v1/schema?model= for correct schema)
- Network timeout during inference for complex prompts
- Payment settlement failure on selected chain (Tempo, Base, or Solana)
- Rate limiting if too many concurrent requests are submitted
