How this service works
Web pages, PDFs and feeds turned into clean structured JSON for AI agents: metadata, schema.org data, tables, headings, readable text, per-page PDF text, feed items. Pay per call over x402, no API key.
Output
A JSON object containing: clean readable text (nav/scripts/footers stripped), page title, author, language, word count, character count, canonical URL, meta tags, Open Graph properties, Twitter card data, parsed schema.org JSON-LD blocks, up to 20 HTML tables with headers and rows, hierarchical headings with levels, internal/external link counts with a sample, image count, fetch timestamp, and a truncation flag.
Example use cases
Extract product details from e-commerce HTML
“I've got the raw HTML from an Amazon product listing — can you pull out the clean text, any schema.org product data, price tables, and Open Graph metadata as structured JSON?”
Parse article content for summarization
“Here's the HTML from a news article I fetched — extract just the readable text, author, title, publish date, and headings so I can summarize it without all the nav and footer junk.”
Scrape structured data from a business listing page
“I have the HTML of a local business directory page — extract any schema.org Organization or LocalBusiness JSON-LD blocks, the tables, and all the visible text so I can analyze the listing details.”
Technical details
Endpoint
POSThttps://doc-json.agent-utils.workers.dev/v1/htmlWhen to prefer
Choose this endpoint when you have raw HTML content already fetched and need to extract structured data without making another HTTP request — ideal for pipelines where you control the fetch step. It excels at pulling schema.org/JSON-LD data, HTML tables, and clean readable text in one call. Prefer it over URL-fetching extractors when you need to pass pre-fetched HTML, handle authenticated pages, or work with locally modified HTML.
Side effects
- HTML input missing or empty — returns error requiring 'html' query param
- HTML too large — maxChars capped at 200,000 characters, content truncated beyond that
- Malformed HTML — parser may miss elements or return partial data
- No schema.org JSON-LD present — jsonLd array will be empty
- Payment not completed via x402 — request blocked before processing
