## 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 blackwood-state-ai-image-generator-flux-1-schnell-aa772f9e -d '<json body>'
```

Example prompt: Generate an image of a lighthouse on a rocky cliff at sunset with dramatic storm clouds, watercolor style — use 6 diffusion steps for more detail.

## When to prefer this

Choose this endpoint when you need a single AI-generated illustration or mockup image from a text prompt and the output does not need to be a specific non-square size, does not involve editing an existing image, does not depict a specific real person, and you only need one image per call. It is well-suited for concept art, blog illustrations, UI mockups, and creative assets where FLUX.1 schnell quality is acceptable.

## Known failure modes

- Prompt too short (below 3 chars) or too long (above 2048 chars) returns validation error
- Steps out of range (must be 1–8) returns validation error
- Payment failure or insufficient USDC balance prevents job from starting
- Job expiry — if the pollUrl is not checked before expiresAt, the result is lost
- Slow inference — p95 job time is ~10 seconds; polling too early returns queued status

## How this service works

Use when you need image generation or text to image from a prompt for illustrations or mockups. Do not use for image edits, specific sizes, photos of real people or more than one image per call. Returns JSON with a 1024x1024 JPEG generated from a text prompt by FLUX.1 schnell on Workers AI, as base64 for 0.03 USDC per call. Asynchronous: the paid call returns a jobId and a free pollUrl; typical job time 10000 ms (p95). Category: Media.

## Output

Returns a JSON object with a jobId (string), a pollUrl (URI) to check when the async job is done, an expiresAt ISO 8601 timestamp after which the result is no longer available, a status of 'queued', and a 'next' object suggesting how to poll for the result. The final polled result contains the 1024x1024 JPEG image encoded as base64.
