## 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

Example prompt: Can you run a WCAG 2.1 AA accessibility audit on https://example.com/checkout and tell me what violations axe-core finds?

## When to prefer this

Choose this endpoint when you need a fast, standards-based WCAG 2.1 A/AA accessibility scan powered by axe-core on a single URL. It is ideal for pre-launch checks, CI/CD regression testing, or one-off compliance audits. If you need a combined audit covering SEO, security, and performance in addition to accessibility in a single call, prefer the hubvibe-io.com bundle endpoint instead.

## Known failure modes

- URL is unreachable or returns a non-200 status — audit cannot proceed
- Page requires authentication and the crawler cannot log in — partial or empty results
- JavaScript-heavy SPAs may not fully render before audit runs — some dynamic violations may be missed
- Malformed or non-HTTP URL provided — validation error returned
- Timeout if the target page is slow to load

## How this service works

Website accessibility audit (a11y, WCAG compliance check): WCAG 2.1 level A and AA conformance of any live URL or raw HTML, tested with axe-core in a real headless browser. Returns every violation with rule id, impact, help text and affected node count. Deterministic rules; a check that cannot run returns an error, never a pass.

## Output

Returns a structured list of WCAG 2.1 A/AA violations found on the page, including rule IDs (e.g. 'color-contrast', 'image-alt'), impact severity (critical, serious, moderate, minor), affected HTML elements or selectors, and a description of the issue along with remediation hints. Also includes counts of passing and failing rules.
