Perplexity

Audit any URL's accessibility issues.

Use `audit_url_accessibility` to run a thorough WCAG audit on a specific web page. It identifies compliance markers and flags all major accessibility issues against established standards. You just paste the target URL, and the agent spits out a clear report detailing exactly what's broken, letting you know where to focus your fixes immediately.

Verify the WCAG service status.

Need to confirm if the WCAG.com API is actually up? Just call `check_api_status`. This tells you right away if the entire WCAG service endpoint is operational, saving you time debugging failed connections. It’s a simple check that confirms connectivity before your whole build pipeline gets stalled because of an external dependency issue.

Get detailed accessibility rules.

The `get_wcag_guideline_details` tool lets you pull specific metadata and recommendations for any WCAG guideline. If you're arguing about a technical requirement, you get the official source material right in your chat. It’s perfect for documentation or when you need to explain *why* a certain fix is mandatory, using the precise language of accessibility standards.
