How this service works
Call when an agent needs content of meta name=description via //meta[@name='description']/@content from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/xpath-meta-description first.
Output
Returns the string value of the content attribute from the first matching <meta name='description'> element found in the fetched or provided HTML. If no meta description tag is present, returns an empty or null result.
Example use cases
SEO audit of competitor pages
“Pull the meta description from https://www.competitor.com/about so I can see what they're using for their SEO snippet.”
Link preview generation
“I need the meta description from https://techcrunch.com/2024/01/15/some-article to build a link preview card — can you grab it?”
Content cataloging from raw HTML
“I have this HTML string from a scraped page — can you extract the meta description tag content from it?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-meta-description?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need specifically the meta description tag content from a webpage, particularly for SEO auditing, link preview generation, or content cataloging workflows. Prefer this over generic scraping endpoints when you only need this one XPath-targeted field. Use the unpaid POST /v1/sandbox/xpath-meta-description for testing before incurring the $0.002 USDC charge.
Side effects
- URL is unreachable or returns non-200 status — fetch fails with network error
- URL is a private/internal IP address — rejected by SSRF protection
- HTML does not contain a meta name=description tag — empty or null content returned
- HTML string exceeds 200,000 character limit — request rejected
- URL string is fewer than 8 characters or malformed — validation error
- Page requires JavaScript rendering — static HTML fetch may miss dynamically injected meta tags
