When to prefer

Use this endpoint when you need to collect and deduplicate specific HTML attribute values from anchor/link elements on a static page, particularly when you want to filter by a keyword term and exclude previously seen values. It is ideal for inventory audits of link metadata, navigation analysis, or building unique identifier lists from web pages without needing JavaScript rendering or authentication bypass.

Side effects

URL is inaccessible, behind a login wall, or returns non-200 status — no content to parse
JavaScript-rendered content not present since only static HTML is parsed
No anchor elements matching the term or attribute found — returns empty result
HTML input exceeds 100,000 character limit — request rejected
Attribute name does not match pattern ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$ — validation error
Term field empty or missing — minLength of 1 enforced
