## 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 wafermap-xyz-image-describe-llama-4-scout-vision-a433f553 -d '<json body>'
```

Example prompt: Look at this image — https://example.com/product-photo.jpg — and tell me what products are visible and what colors they come in.

## When to prefer this

Choose this endpoint when you need to ask a specific question about or get a description of an image accessible via a public HTTPS URL, especially when you want Llama 4 Scout's multimodal vision capabilities. It is particularly suitable for automated pipelines that process image links without requiring local file uploads. Prefer it over generic OCR services when you need semantic understanding rather than raw text extraction, and over heavier vision APIs when cost efficiency matters at $0.004 per call.

## Known failure modes

- Image URL is not HTTPS — rejected by schema validation
- Image format not supported (only PNG, JPEG, WebP accepted)
- Image URL is unreachable or returns a non-200 HTTP response
- Image file too large or takes too long to fetch
- Question exceeds 1000 character limit
- Ambiguous or low-resolution image may result in vague or incorrect descriptions
- Model hallucination on unclear image regions
