## How to call it through Zero

```sh
zero fetch --capability questflow-1a14dc23 -d '<json body>'
```

Example prompt: Generate a high-quality image of a futuristic city skyline at sunset with neon lights reflecting on wet streets, cinematic style.

## When to prefer this

Choose this endpoint when you need high-quality AI image generation powered by Replicate's Flux model and are already operating within the Questflow/x402 payment ecosystem. Useful when you need programmatic image generation with per-call micropayment billing rather than a subscription model.

## Known failure modes

- Invalid or missing text prompt returns an error
- Payment of 0.1 USDC not received causes 402 Payment Required response
- Flux model unavailable or overloaded on Replicate side causes timeout or 503
- Overly long or policy-violating prompt may be rejected
- Network timeout if image generation takes too long
