How this service works
Extract the page's classes as json: fetches the URL, pulls every classes 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 listing every distinct CSS class name found on the fetched page, along with a count of how many class values were extracted. The response is structured for direct consumption by agents or pipelines.
Example use cases
CSS audit for a competitor site
“Pull all the CSS classes from https://competitor.com/landing and give me the full JSON list so I can see what CSS framework they might be using.”
Frontend class inventory for migration
“I need a complete JSON array of every CSS class used on https://myapp.io/dashboard — we're migrating our styles and want a full inventory.”
Automated style analysis pipeline
“For the URL https://blog.acme.com/home, extract all the HTML class names as JSON so I can feed them into my style analysis script.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/page/classes/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, structured JSON extraction of CSS class names from a static or server-rendered HTML page without spinning up a browser. It is ideal for automated pipelines, CSS audits, or frontend analysis tasks where only class attributes are needed. Prefer it over full-page scraping APIs when you specifically want class data in a machine-readable format at minimal cost ($0.01/page).
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page has no class attributes — returns an empty array with count 0
- URL is behind authentication or a bot-blocking mechanism — content may be incomplete
- Malformed or dynamically rendered page (JavaScript-heavy SPA) — classes injected by JS at runtime may be missed since no browser is used
