How this service works
Extract the page's h4 as json: fetches the URL, pulls every h4 element and returns them as a JSON array, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.
Output
A JSON object containing an array of all H4 text strings found on the fetched page and a numeric count of how many H4 elements were found.
Example use cases
Audit page heading structure
“Fetch all the H4 headings from https://docs.mycompany.com/guide and give me a JSON list so I can review how the page is structured.”
Content extraction for data pipeline
“Pull every H4 element from https://blog.example.com/top-tools as JSON — I need the headings and a count to feed into my content indexing pipeline.”
Competitive research on page topics
“Extract all H4 headings from https://competitor.com/features as JSON so I can see what sub-topics they're covering on that page.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/page/h4/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need only H4 headings from a page in structured JSON format without a browser, especially for pipelines, agents, or automation where clean structured output is required and no JavaScript rendering is needed. Prefer over full-page scrapers when you only need this specific heading level.
Side effects
- URL is unreachable or returns a non-200 status — empty result or error response
- Page has no H4 elements — returns an empty array with count 0
- URL is paywalled or requires authentication — content not accessible
- Rate limiting or network timeout on the target server — fetch failure
- Malformed URL input — request error returned
