## When to prefer this

Choose this endpoint when you need a structured, evidence-based audit of a specific URL's AEO and SEO readiness — particularly for assessing whether a page is likely to be cited or surfaced by AI answer engines. It is especially useful for content creators, SEO practitioners, and AI agents managing web presence who need actionable, prioritized findings rather than raw HTML or general web scraping.

## Known failure modes

- Non-public or credential-protected URLs return an error or empty result
- URLs on non-standard ports may be rejected by schema validation
- Pages with heavy JavaScript rendering may yield incomplete text extraction
- Rate limiting or rendering timeouts may produce partial results
- Invalid or malformed URL input returns a validation error
