How this service works
Extract the page's h3 as markdown: fetches the URL, pulls every h3 element and returns them as a Markdown list, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.
Output
A Markdown-formatted list of all H3 elements found on the requested page, along with a count of how many H3 elements were extracted.
Example use cases
SEO heading structure audit
“Grab all the H3 headings from https://competitor.com/pricing and give me a markdown list so I can see how they structure their page sections.”
Content outline extraction from article
“Pull every H3 subheading from this news article at https://techcrunch.com/2024/05/01/openai-news and show them as a markdown list so I can get a quick outline.”
Documentation section inventory
“Extract all H3 headings from https://docs.stripe.com/payments and return them as a markdown list — I want to see every subsection they cover.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/page/h3/markdown?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, structured extraction of only H3 headings from a page — ideal for SEO audits, content outlines, or pipeline steps that need a specific heading level without full-page parsing. Prefer this over full-page scrapers when you only need H3s and want Markdown output without spinning up a browser.
Side effects
- URL is unreachable or returns a non-200 status — no headings returned
- Page has no H3 elements — returns an empty list with count of 0
- URL is missing from query params — request fails with validation error
- Page blocks scraping via robots.txt or rate limiting — fetch may fail
- Malformed URL input — returns an error response
