How this service works
Call when an agent needs h1–h6 text extracted from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/profile-headings first.
Output
A list of all heading elements (h1 through h6) found in the page or HTML, with their tag level and text content, enabling agents to understand the document's structure and section hierarchy.
Example use cases
Audit website content structure
“Pull all the headings from https://mybrand.com/products so I can see how the page is organized and whether we're missing any important sections.”
Extract headings from raw HTML
“I have this HTML snippet — can you extract all h1 through h6 headings from it so I can understand what topics it covers?”
Competitive page analysis
“Grab all the headings from https://competitor.com/pricing so I can compare their page structure to ours.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-headings?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract the heading structure (h1–h6) from any public webpage or HTML blob, especially in automated pipelines where paying $0.002 USDC per call is acceptable. If a free sandbox alternative at POST /v1/sandbox/profile-headings is available, prefer that first. Choose this over general scraping tools when you specifically need heading text only, not full page content.
Side effects
- URL is not publicly accessible or returns a non-200 status
- SSRF check blocks internal/private IP addresses or reserved hostnames
- HTML input exceeds the 200,000 character limit
- URL exceeds the 2,048 character limit
- Page has no heading elements, returning an empty list
- Malformed HTML that cannot be parsed
