Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 cortexcloud-ai-image-generation-flux-stability-e2deac1f
```

Example prompt: Generate a photorealistic image of a red fox sitting in a snowy forest at dusk — use the Flux model, 1024x1024 size, and give me 1 image as a URL.

## When to prefer this

Choose this endpoint when you need to generate images via a pay-per-call USDC micropayment model without a subscription, or when you want access to both Flux and Stability AI models through a single OpenAI-compatible interface. Prefer this over raw OpenAI DALL-E if you want Flux-based diffusion outputs or need crypto-native billing on Base.

## Known failure modes

- Invalid or unsupported model name returns an error
- Prompt violates content policy and is rejected
- Unsupported image size string causes a bad request error
- Payment not received or USDC balance insufficient blocks the request
- Network timeout if the model backend is slow to respond
- n exceeds provider limits causing a quota error

## How this service works

OpenAI-compatible AI and data API for agents. Pay per call in USDC on Base via x402 — no API keys, no subscriptions, no lock-in.

## Output

Returns one or more AI-generated images corresponding to the prompt, either as URLs or base64-encoded image data, depending on the response_format parameter. Each call produces the specified number of images (n) at the requested size using the chosen model.
