Perplexity

Run Automated Web Audits

For headless pipelines, pipe URLs into `audit_url_accessibility`. This tool runs a full WCAG accessibility audit and outputs the compliance markers directly to stdio. It's perfect for CI/CD scripts. The output is clean JSON detailing every identified issue against specified web standards.

Check Service Operational Status

Never assume a service is up. Execute `check_api_status` to verify the WCAG.com Accessibility API status. This confirms the external dependency is live before your main script runs. It keeps your shell scripts from failing due to downtime.

Retrieve Guideline Details

Need specific guidance? Use `get_wcag_guideline_details` to pull metadata and recommendations for a precise WCAG guideline ID. Pipe this data into your reporting tool. It's deterministic: input the rule, get the structured output.
