extract-headings-as-text

Choose this endpoint when you need a clean, plain-text list of a page's headings quickly and cheaply ($0.01/call) without spinning up a browser or writing a scraper. It is ideal for agents and pipelines that need structured page outline data — such as SEO audits, content summarization preprocessing, or competitive analysis — and where the output format of plain text lines is sufficient. Prefer sibling endpoints if you need headings in Markdown format (e.g. extract-h6-as-markdown) or JSON.

• URL is unreachable or returns a non-200 status — endpoint may return an error or empty result
• Page has no heading elements — returns zero count with empty lines
• URL is behind a login or bot-detection wall — content may not be accessible
• Malformed or missing URL parameter — request fails with a validation error
• Page uses JavaScript-rendered headings — static fetch may miss dynamically injected headings
