## 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 sparks-re-api-wcag-2-1-aa-accessibility-audit-e186fcab -d '<json body>'
```

Example prompt: Can you run a WCAG 2.1 AA accessibility audit on https://digisparks.net and tell me whether it's ADA Title II ready and what violations were found?

## When to prefer this

Choose this endpoint when you need automated WCAG 2.1 AA compliance validation for a specific URL or raw HTML snippet, especially in real estate or government housing contexts where ADA Title II readiness is required. It is ideal for pre-launch audits, regulatory compliance checks, or continuous accessibility monitoring of individual pages. Prefer this over generic accessibility tools when you need a structured JSON result with a numeric compliance score and an explicit ADA Title II ready flag.

## Known failure modes

- Invalid or unreachable URL returns an error without compliance data
- Malformed HTML may cause incomplete parsing and inaccurate results
- Dynamic JavaScript-rendered content may not be fully audited if it requires browser execution
- Missing both url and html fields results in a bad request error
- Rate limiting or payment failure returns a 402 Payment Required response
