How this service works
Extract the page's h3 as json: fetches the URL, pulls every h3 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 array of all H3 element text contents found on the fetched page, along with a count of how many H3 elements were found. The response is structured and machine-readable, suitable for downstream agent or pipeline processing.
Example use cases
Audit page section structure
“Pull all the H3 headings from https://docs.myproduct.com/getting-started as a JSON array so I can see how the page is organized.”
Content pipeline heading ingestion
“Fetch all H3 elements from https://news.ycombinator.com as structured JSON so my pipeline can process each section heading.”
SEO heading analysis
“Grab every H3 tag from https://competitor.com/features as a JSON list — I want to see what sub-sections they're highlighting on that page.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/page/h3/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a clean, structured JSON list of H3 headings from a specific webpage without running a full browser. Ideal for agents and automated pipelines that need to quickly audit heading structure, feed headings into downstream processing, or compare section organization across pages. Prefer this over full-page scraping when you only need H3 elements and want a lightweight, cost-effective ($0.01/page) call with predictable output schema.
Side effects
- URL is unreachable or returns a non-200 status, resulting in an error response
- Page has no H3 elements, returning an empty array with count 0
- URL points to a non-HTML resource (PDF, image, etc.) where H3 extraction is not applicable
- Rate limiting or payment failure prevents the call from completing
- URL is malformed or missing, causing a bad request error
