How this service works
Extract the page's headings as json: fetches the URL, pulls every headings 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 heading objects found on the fetched page, each containing the heading text and its level (h1–h6), plus a total count of headings extracted.
Example use cases
Audit article structure for SEO
“Grab all the headings from https://myblog.com/how-to-grow-tomatoes and give me them as JSON — I want to check whether the h1 and h2 hierarchy makes sense for SEO.”
Build a table of contents from a page
“Pull all the headings from https://docs.myproject.io/getting-started as JSON so I can automatically generate a table of contents for that documentation page.”
Validate competitor page outline
“Fetch https://competitor.com/product and extract every heading element as a JSON array — I want to see how they've structured their product page compared to ours.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/page/headings/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, structured JSON extraction of only heading elements from a static or server-rendered web page, without spinning up a browser. Ideal for agents and pipelines that need to analyze page structure, generate tables of contents, or audit heading hierarchies at $0.01 per page. Prefer alternatives if the page is JavaScript-rendered, if you need all text content (use extract-text-as-text), or if you need bulk processing of many URLs at once (use the bulk or watch variants).
Side effects
- URL is unreachable or returns a non-200 status — endpoint returns an error or empty result
- Page uses JavaScript-rendered content that requires a browser — headings may be missing since no browser is used
- URL parameter is missing or malformed — request fails with a validation error
- Page has no heading elements — returns an empty array with count of zero
- Network timeout on slow or large pages — may return a timeout error
