## 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-creative-upscaling-via-locus-x402-5ba0fcb6 -d '<json body>'
```

Example prompt: Take this photo and creatively upscale it using Stability AI — use the prompt 'a vibrant sunlit forest clearing with rich foliage', set creativity to 0.6, and output as PNG.

## When to prefer this

Choose this endpoint when you need AI-driven creative upscaling that goes beyond simple interpolation — especially when you want to guide the enhancement with a text prompt or style preset. It is ideal for cases where the source image is low-resolution or lacks detail, and you want the model to intelligently invent plausible high-frequency details. Prefer it over standard upscalers when artistic reinterpretation or style-coherent enhancement matters. Best suited for single-image workflows with per-call micropayment via USDC.

## Known failure modes

- Missing or invalid source image causes a 400 error
- Prompt field absent or empty may result in degraded enhancement
- Creativity value outside 0–1 range may be rejected or clamped
- Unsupported output_format value returns a validation error
- Payment failure (insufficient USDC balance) results in a 402 response
- Timeout or server-side generation failure returns a non-success response with no image
