How this service works
Call when an agent needs text of //h2 via //h2 from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/xpath-h2 first.
Output
A list of text strings, each representing the inner text of an H2 element found on the page or in the provided HTML, returned in document order and de-duplicated or raw depending on the service's behavior.
Example use cases
Blog post section outline
“Grab all the H2 headings from https://techcrunch.com/2024/01/ai-trends so I can see how the article is structured.”
Competitor page analysis
“Extract all H2 headings from this HTML I have — I want to see what sections a competitor's landing page uses to structure their content.”
SEO heading audit
“Pull all the H2 tags from https://mysite.com/services so I can check whether our section headings are keyword-optimized.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-h2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need H2-level headings from a page and want a targeted, low-cost extraction rather than a full heading outline. Prefer the free sandbox variant (/v1/sandbox/xpath-h2) when available. Use the paid endpoint when the sandbox is unavailable or rate-limited. Choose this over a full-heading-outline endpoint when only H2s are needed and you want to minimize cost.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- URL points to an internal/private IP (SSRF attempt) — blocked by SSRF protection
- HTML or URL exceeds size limits — request rejected
- Page contains no H2 elements — returns empty list
- Malformed HTML input — parser may return partial or empty results
- Payment not included or insufficient — 402 Payment Required
