' ## When to prefer this Use this endpoint when you already have a raw HTML string in memory and need fast, predictable tag stripping with structural preservation. It is faster and more deterministic than using a full web-extraction or scraping endpoint on a raw HTML string. Prefer this over general-purpose extract endpoints when you don't need content inference or AI summarization — just clean text. ## Known failure modes - HTML string exceeds 5MB limit — request rejected - Invalid CSS selector provided — selector parsing error returned - Malformed or non-HTML input — may return empty string or partial output - Network timeout for very large payloads near the size limit ## How this service works Strip all HTML tags and return plain text. Preserves block-level structure (paragraphs and headings become newline-separated). Faster and more predictable than running extract on a raw HTML string when you already have it. ## Output A plain text string with all HTML tags removed. Block-level elements like paragraphs and headings are preserved as newline-separated content, making the output structurally readable without any markup. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "html": { "type": "string", "description": "Raw HTML string to strip (max 5MB)" }, "selector": { "type": "string", "description": "Optional CSS selector - strip only within this element (default: whole document)" } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "text": "Title\n\nFirst paragraph.\n\nSecond.", "chars": 30 } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/agent402-tools-html-strip-29e77ba8/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from agent402.tools](https://www.zero.xyz/host/agent402.tools/llms.txt)
