## 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 sift-web-tools-ai-image-generation-f4303acc
```

Example prompt: Generate an image of a serene mountain lake at golden hour with pine trees reflecting in the still water — use a 16:9 aspect ratio.

## When to prefer this

Choose this endpoint when an AI agent needs to generate a brand-new image from a text description without any image input, and payment is handled via x402 USDC on Base (pay-per-call, no subscription). Ideal for agents that want a pay-as-you-go model at $0.08 per image with no upfront commitment. Prefer this over self-hosted or subscription-based image APIs when operating in a crypto-native, per-call billing context.

## Known failure modes

- Prompt too short (under 3 chars) or too long (over 2000 chars) returns a 400 error
- Invalid aspect ratio format returns a 400 error
- Payment failure or insufficient USDC balance returns a 402 before generation begins
- Server-side generation failure returns a 500 with no image and no charge
- Network timeout may leave generation state unknown

## How this service works

Generate an image from a text prompt (PNG). Text-to-image with Google's Gemini image model. Aspect ratios 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9. Prompts refused by the model's safety filter are not charged.

## Output

Returns a PNG image file generated from the given text prompt. The image is only returned (and payment charged) on a successful HTTP 200 response. No metadata or JSON wrapper — the raw image bytes are the response body.
