Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability portal-generation-ai-image-generation-flux-sdxl-recraft-seedream-0d0f071d -d '<json body>'
```

Example prompt: Generate an image of a futuristic cityscape at dusk with neon lights reflecting on wet streets, using the FLUX model with 30 inference steps.

## When to prefer this

Choose this endpoint when you need text-to-image generation with access to multiple model options (FLUX, SDXL, Recraft, SeeDream) via a pay-per-use x402 micropayment model. Prefer over alternatives when model variety matters, when you want to pay per call without a subscription, or when building agents that use x402 payment rails.

## Known failure modes

- Missing required 'prompt' field returns a 400 validation error
- Invalid model ID may result in a 400 or fallback to default model
- Payment not fulfilled (x402 flow not completed) results in a 402 Payment Required response
- Server-side generation failure returns a 500 error
- Prompt content policy violation may result in a 400 or 403 error
- Invalid seed or steps values may cause generation failure
