## 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 stability-ai-conservative-upscale-via-locus-x402-99896669 -d '<json body>'
```

Example prompt: Take this product photo and upscale it to a high-resolution PNG — use the prompt 'a sleek modern coffee mug on a white background' to guide the enhancement, set creativity to 0.3 so it stays close to the original, and exclude any blurry or noisy artifacts.

## When to prefer this

Choose this endpoint when you need to enlarge an existing image while staying faithful to the original content — the 'conservative' mode minimizes hallucinated detail. Prefer it over creative upscaling options when accuracy and fidelity to the source matter more than adding new textures. It is ideal for product photos, archival images, or AI-generated art that needs print-ready resolution. Use when you can pay per-call in USDC via the x402 protocol without managing API keys.

## Known failure modes

- Invalid or missing source image returns an error in the data field
- Creativity value outside 0–1 range may cause validation failure
- Unsupported output_format string results in a bad request error
- Payment failure or insufficient USDC balance causes a 402 response before processing
- Very large input images may time out or be rejected
- Missing required prompt field may result in degraded or failed output
