How this service works
Call when an agent needs h2 text extracted from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/profile-h2 first.
Output
Returns a list of H2 heading text strings extracted from the provided URL or HTML. Each item corresponds to the inner text of one H2 element found on the page.
Example use cases
SEO competitive content audit
“Grab all the H2 section headings from https://competitor.com/guide/seo-basics — I want to see how they've structured their content outline.”
Article structure extraction
“Extract the H2 headings from this HTML I've got here — I need to build a table of contents from the section titles.”
Website section mapping
“Can you get me all the H2 headings from https://docs.someproduct.io/getting-started so I can map out the sections they cover?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-h2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need H2 heading text from a public page or raw HTML and want an SSRF-safe, paid extraction service. Prefer the free sandbox endpoint /v1/sandbox/profile-h2 first for testing or low-volume use. Choose this over general HTML scrapers when you need isolated H2 extraction with guaranteed safety controls.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- HTML input exceeds 200,000 character limit — request rejected
- URL is too short (under 8 characters) or malformed — validation error
- No H2 elements found on the page — returns empty list
- SSRF-blocked URL (private IP range or internal host) — request rejected for safety
