## 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 x402img-ai-image-generation-f4a09974 -d '<json body>'
```

Example prompt: Generate an image of a cozy mountain cabin in winter with snow on the roof and warm light glowing from the windows — use the quality tier for a crisp, high-detail result.

## When to prefer this

Choose this endpoint when you need AI-generated images with selectable quality tiers and per-call micropayment pricing via x402. The fast tier ($0.02) is ideal for quick drafts and iteration; the quality tier ($0.10) suits production assets; the premium tier ($0.20) is best when text rendering accuracy and maximum image fidelity are required. Prefer this over alternatives when your agent stack already supports x402 payment protocol and you want cost-controlled generation without subscription commitments.

## Known failure modes

- Invalid or empty prompt returns an error response with success: false
- Unsupported tier value causes a validation error
- Payment not received or insufficient funds results in a 402 Payment Required response
- Image URL expires after the expiresAt timestamp, making the link inaccessible
- Network timeout for premium tier due to longer generation time
- Content policy violation on prompt may result in rejected generation

## How this service works

Pay-per-call image generation API for AI agents. Three quality tiers: fast ($0.02), quality ($0.10), premium ($0.20).

## Output

Returns a JSON object containing a temporary URL to the generated image (imageUrl), an expiration timestamp (expiresAt), the model used, the quality tier selected, a success boolean, and an optional notice message. The image URL is time-limited and should be downloaded promptly.
