How this service works

Strip all HTML tags and return plain text. Preserves block-level structure (paragraphs and headings become newline-separated). hiddenContent reports text a reader cannot see (HTML comments, display:none or hidden elements, white-on-white or off-screen text, zero-width characters) and quotes any of it that reads as an instruction to an AI; send hidden: "drop" to leave it out of the text. 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.

Example use cases

Example prompt

“Strip all the HTML tags from this string and give me just the readable text, keeping paragraphs and headings as separate lines: '<html><body><h1>Hello</h1><p>World</p></body></html>'”

Endpoint

When to prefer

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.

Side effects

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

Input

Schema · Request body

Field	Type	Description
html	string	Raw HTML string to strip (max 5MB)
hidden	string	What to do with content a reader cannot see (HTML comments, display:none or hidden elements, white-on-white or off-screen text, zero-width characters): "keep" (default) converts it like everything else, "drop" removes it first. Either way hiddenContent reports what was found and quotes any hidden text that reads as an instruction to an AI.
selector	string	Optional CSS selector - strip only within this element (default: whole document)
