How this service works
Call when an agent needs h2 text via h2 from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/css-h2 first.
Output
A list of all H2 heading text values found in the provided URL's page content or the supplied raw HTML, returned as structured data. If a URL is provided the service fetches the page (with SSRF protection) and parses its H2 elements; if raw HTML is provided it is parsed directly.
Example use cases
Section outline from article
“Pull all the H2 headings from https://docs.python.org/3/library/functions.html so I can see how the page is structured.”
Competitor page analysis
“Extract all H2 headings from https://www.competitor.com/features — I want to see what sections they highlight on their features page.”
H2 headings from raw HTML
“I have some raw HTML from a scraped page — can you extract just the H2 heading text from it? Here's the HTML: <html><body><h2>Introduction</h2><h2>Getting Started</h2></body></html>”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-h2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need only H2 headings from a page — not all headings (h1–h6) — and want a lightweight, cost-efficient extraction ($0.001 USDC). Prefer this over the broader all-headings endpoint when you only care about second-level headings. If you already have the raw HTML, pass it directly to avoid a second network fetch.
Side effects
- URL points to a private/internal IP address (SSRF rejection)
- URL is unreachable or returns non-200 status
- HTML input exceeds 200,000 character limit
- No H2 tags found in the page or HTML (empty result)
- Malformed URL input
- Payment not completed — 402 response returned
