How this service works
Extract the main article from a web page with Mozilla Readability — drops nav, ads, sidebars and footer boilerplate. Send inline {html} or a public {url} to fetch (SSRF-checked). Returns the article title, byline, cleaned HTML content, plain textContent, excerpt, character length, language and site name. THE pre-processing step before sending a page to an LLM. Distinct from html-to-md (which renders Markdown). Max 5 MB.
Output
Returns a JSON object with the article title, byline (author), cleaned HTML content, plain textContent (boilerplate-free), a short excerpt, total character length, detected language code, and site name — everything needed to pass clean article text to an LLM.
Example use cases
News aggregation for content curation
“I need to pull articles from these five news links and extract just the main content, titles, and authors so I can summarize them for my team. Can you clean them up and give me the plain text for each?”
Research synthesis from multiple sources
“Go through these blog posts and documentation pages I've gathered, strip out all the navigation and ads, and give me the core text and title from each one — I need to compile them into a knowledge base.”
Content moderation and safety filtering
“Check these URLs for problematic content — pull out the clean article text, author, and title from each page so I can review what's actually being published.”
Technical details
Endpoint
POSThttps://402utils.com/v1/readability?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to preprocess a web page or raw HTML for LLM consumption — especially when you want clean plain text and structured metadata (title, byline, language) rather than Markdown. Prefer this over html-to-md when you need the plain textContent field or structured article metadata rather than a rendered Markdown document. Best for news articles, blog posts, and any long-form content page.
Side effects
- URL is not publicly accessible or returns non-200 status
- HTML exceeds 5 MB limit — returns error
- SSRF check blocks private/internal IP ranges
- Page has no extractable main article (e.g. login wall, empty body) — returns null content fields
- Neither url nor html provided — returns validation error
- Malformed URL format — returns schema validation error
