## 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-accessibility-signals-barrierefreiheit-ba5d7c47 -d '<json body>'
```

Example prompt: Can you scan https://example.de for BFSG accessibility signals — I need to know if it has proper lang attribute, alt texts, landmark elements, and form labels as a quick heuristic check for German Barrierefreiheit compliance?

## When to prefer this

Choose this endpoint when you need fast heuristic accessibility signals specifically scoped to German BFSG/Barrierefreiheit requirements, including lang, alt, landmarks, and labels. It is purpose-built for DACH web compliance workflows and accepts either a live URL or raw HTML, making it useful for both pre-launch audits and CI pipelines. Not a substitute for a certified WCAG audit, but ideal for quick automated signal detection in an agent workflow.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status
- HTML content is too large or complex to parse within timeout
- Dynamic JavaScript-rendered content may not be fully analyzed
- URL behind authentication or firewall returns no crawlable content
- Malformed HTML may produce incomplete signal extraction
