# AI Image Generator (Cloudflare Workers AI / FLUX.1)

> AI Image Generator (Cloudflare Workers AI / FLUX.1) is a paid API for AI agents from ai-policy-kit.moneymaker-ai.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Generates a 1024×1024 AI image from a text prompt using FLUX.1 [schnell] via Cloudflare Workers AI, with optional style selection and prompt enhancement.

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 ai-image-generator-cloudflare-workers-ai-flux-1-494f77cf
```

Example prompt: Can you generate a pencil sketch of an old bicycle leaning against a brick wall — use the pencil_sketch style and let it enhance the prompt automatically?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01) text-to-image generation with automatic style detection and prompt enhancement, especially if you want named artistic styles like pencil_sketch, anime, watercolor, or flat_vector. It runs on Cloudflare's edge via FLUX.1 [schnell] (Apache-2.0), making it fast and serverless. Prefer alternatives if you need very high photorealism, video, audio, or multi-image batch generation.

## Known failure modes

- Prompt fails keyword safety screen — returns error before generation begins
- Prompt is too long (over 600 characters) — validation error
- Invalid style enum value — rejected by schema validation
- steps parameter out of range (must be 1–8) — validation error
- Cloudflare Workers AI upstream timeout — may return 500 or empty response
- Payment of 0.01 USDC not fulfilled via x402 — 402 Payment Required response

Generate an AI_POLICY.md and a pull request template with an AI-disclosure section for your open-source repo. Free, runs in your browser.

## Output

A JSON object containing the generated image as a base64-encoded JPEG string (~400KB typical), along with the image dimensions (1024×1024), the style applied, number of diffusion steps used, the final enhanced prompt, the AI engine name, approximate byte size, and a safety screening report indicating whether keyword and LLM screens passed.
