```sh
zero fetch --capability api-the402-ai-d9ea082e -d '<json body>'

## When to prefer this

Use this endpoint when you need a structured, paid WCAG accessibility audit of a specific URL and want a detailed compliance report with actionable remediation steps. Prefer this over free browser-based tools when you need programmatic access to audit results for automation or reporting pipelines.

## Known failure modes

- Invalid or unreachable URL returns an error response
- Unsupported WCAG standard version causes rejection
- Payment failure via x402 protocol prevents job creation
- Job times out for very large or complex websites
- Rate limiting if too many concurrent audit requests are submitted
