## 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 x402-ai-api-civicmerge-workers-dev-abd114e7 -d '<json body>'
```

Example prompt: Generate a photorealistic image of a futuristic cityscape at night with neon lights reflecting on rain-soaked streets, using the 'pro' quality model at 1024x1024.

## When to prefer this

Choose this endpoint when you need fast, pay-per-call AI image generation with multiple quality tiers (including SDXL, DreamShaper, inpainting, and img2img variants) and want to pay micro-amounts per image without a subscription. Especially useful for agents that need on-demand image creation within an x402 payment workflow.

## Known failure modes

- Invalid model enum value returns 400 error
- Prompt missing from request body returns validation error
- Payment failure (insufficient USDC or x402 protocol error) returns 402 Payment Required
- Width or height out of supported range returns error
- Service unavailable on Cloudflare Workers returns 503
