## 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 haven-image-upscale-2a2ed0bb -d '<json body>'
```

Example prompt: Can you upscale this photo by 4x using face enhancement mode? It's a JPEG portrait and I want the highest quality result.

## When to prefer this

Choose this endpoint when you need AI-powered image upscaling with either general (auto) or face-optimized enhancement, supporting 2x or 4x enlargement of PNG or JPEG images, and can tolerate async processing (up to ~5 minutes). Prefer face mode for portrait or headshot images. Best suited for agents that can handle polling workflows and x402 USDC micropayments.

## Known failure modes

- Invalid or corrupt base64 image data — returns error on submission
- Unsupported media type (not image/png or image/jpeg) — rejected at input validation
- Upscale factor not 2 or 4 — enum validation failure
- Job timeout if processing exceeds pollBudgetSeconds (1200s) — result may not be available
- Payment failure via x402 protocol — request blocked without $0.06 USDC
- Image too large or too small for upscaling — possible server-side rejection
- Network timeout while polling statusUrl

## Output

Returns a JSON object with a job ID, initial status ('queued'), a result URL to fetch the upscaled image once complete, a status polling URL, an estimated completion time in seconds (etaSeconds), and a maximum polling budget in seconds. The agent must poll the statusUrl until complete, then retrieve the upscaled image from resultUrl.
