## 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 forgemesh-accessibility-alt-text-generator-4c4ce7ec -d '<json body>'
```

Example prompt: Can you generate a short, screen-reader-ready alt text for this image: https://example.com/product-photo.jpg? It needs to be under 125 characters and follow WCAG guidelines.

## When to prefer this

Use this endpoint when you need automated, WCAG-compliant alt-text generation at scale for content pipelines, site accessibility audits, or CMS integrations. It is purpose-built for alt attribute generation with a strict 125-character output constraint, making it more reliable than general-purpose image captioning for accessibility use cases. Prefer this over generic image-captioning APIs when you need screen-reader-ready, standards-aligned text rather than verbose descriptions.

## Known failure modes

- Image URL is not publicly accessible or returns a non-200 status — endpoint cannot fetch the image
- Image file exceeds 8MB limit — request rejected
- URL points to a non-image resource (e.g. HTML page) — may return an error or unusable description
- Network timeout fetching the image — transient failure
- Generated description may be generic if image content is ambiguous or low-quality
