## 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 payai-agentstools-dev-wcag-2-2-batch-accessibility-checker-ad08ddd6 -d '<json body>'
```

Example prompt: Can you run a WCAG 2.2 accessibility audit on these three HTML files — navbar.html (plain HTML), modal.html (React), and form.html (Vue) — and tell me which ones pass, which need caution, and if any are blocked?

## When to prefer this

Choose this endpoint when you need to audit multiple UI files in a single API call rather than checking them one at a time. It is ideal for CI/CD pipelines, pre-release sweeps of component libraries, or any workflow where batch throughput and a unified rollup summary matter. Prefer it over single-file checkers when you want a worst-case rollup verdict across an entire set of files. Note it provides static accessibility indicators, not a certified legal compliance report.

## Known failure modes

- Malformed or missing markup in a file entry causes that file to return an error verdict
- Unsupported framework identifier may be ignored or trigger a validation error
- Empty file list returns an error or empty results
- Oversized payloads may be rejected if total markup exceeds limits
- Payment failure or missing x402 header results in 402 Payment Required
- Network timeout for very large batches

## How this service works

Batch static accessibility (WCAG 2.2) check of many UI files at once: a list of objects each with a filename, optional framework and markup. Returns a per-file pass, caution or block verdict plus a rollup with the worst verdict and totals by severity. Accessibility indicators, not a legal compliance guarantee.

## Output

Returns a list of per-file results, each with a filename and a verdict of pass, caution, or block based on detected WCAG 2.2 issues. Also returns a rollup object containing the single worst verdict across all files and totals broken down by severity level. These are accessibility indicators for development guidance, not a legal compliance certification.
