How this service works
Call when an agent needs text of //blockquote via //blockquote from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/xpath-blockquote first.
Output
Returns the text content of all //blockquote elements found in the provided URL or HTML, typically as an array or concatenated list of quoted passages extracted via XPath.
Example use cases
Pull quotes from a news article
“Grab all the blockquotes from this news story at https://reuters.com/article/some-story — I want to see every quoted passage the reporter included.”
Extract testimonials from a landing page
“I have the HTML for a product landing page — can you pull out all the blockquote elements so I can see what customer testimonials are featured?”
Audit editorial citations on a blog post
“Can you fetch all the blockquote sections from https://someblog.com/post/2024/analysis so I can review what sources are being quoted?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-blockquote?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract blockquote-tagged content from a public webpage or raw HTML snippet, and you require SSRF safety guarantees. Prefer the unpaid sandbox endpoint (POST /v1/sandbox/xpath-blockquote) for testing or free-tier use. Choose this over generic scrapers when you specifically need XPath-targeted blockquote extraction rather than full-page text or other element types.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with a fetch error
- SSRF-blocked URL (private IP ranges, internal hostnames) — rejected for security reasons
- HTML contains no blockquote elements — returns empty result
- HTML input exceeds 200,000 character limit — request rejected
- URL string shorter than 8 or longer than 2048 characters — validation error
- Malformed HTML that cannot be parsed — may return partial or empty results
- Payment of $0.008 USDC not provided — 402 Payment Required response
