Definition Descriptions HTML Fragment Extraction

Choose this endpoint when you need to extract text from a specific HTML definition description (<dd>) element on a static, publicly accessible webpage or from a supplied HTML string, especially when you know the attribute (e.g. id) and value to target. It is purpose-built for definition list extraction with deduplication support via previous_texts, and operates without JavaScript rendering or authentication. Prefer alternatives if the page requires JS rendering, login, or if you need to extract non-definition-list HTML elements.

• No matching dd element found for the given term and attribute combination — returns empty or null result
• URL is inaccessible, requires JavaScript rendering, or is behind a login — static parser cannot retrieve content
• Attribute pattern does not match the schema regex, causing a validation error
• HTML input exceeds 100,000 character limit — request rejected
• Term is empty or missing — required field causes a schema validation error
• Page returns non-HTML content (e.g. JSON or PDF) — parser finds no fragments
