## 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 bfsg-barrierefreiheit-accessibility-signals-checker-1ec196b3 -d '<json body>'
```

Example prompt: Check the accessibility signals on https://www.beispiel.de — I need to know if it has a lang attribute, a proper title, alt text on images, landmark roles, and labeled form fields for BFSG compliance in Germany.

## When to prefer this

Use this endpoint when you need quick heuristic accessibility signal checks specifically framed for German BFSG/Barrierefreiheit compliance, including lang, title, alt, landmark, and label signals. Prefer this over generic WCAG tools when operating in the DACH regulatory context or when building automated German web compliance pipelines.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error or empty signals
- HTML input is malformed or too large — parsing may fail or return partial results
- Dynamic JavaScript-rendered content may not be fully accessible to the crawler
- Private or auth-gated URLs cannot be fetched — only public pages are supported
- Rate limiting or payment failure may block the request
