Choose this endpoint when you need to extract a specific HTML attribute (e.g. id, class, data-*) from address elements on a static, publicly accessible webpage or a supplied HTML snippet, and you do not need JavaScript rendering. Ideal for structured scraping of contact blocks, address metadata, or semantic HTML tagging on pages that serve full HTML server-side.
Side effects
- URL is not publicly accessible or requires login — returns no result or error
- Page uses JavaScript rendering to populate address elements — static parser will find empty or missing elements
- Attribute name does not match any address element on the page — returns empty or null result
- HTML input exceeds 100,000 character limit — request rejected
- Term does not match any address block content — no result returned
- Invalid attribute name format (not matching pattern ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$) — schema validation error
