How this service works
Call when an agent needs content of meta property=og:title via //meta[@property='og:title']/@content from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/xpath-og-title first.
Output
Returns the string value of the og:title meta property found via the XPath selector //meta[@property='og:title']/@content from the provided URL or HTML. If no og:title is present, returns an empty or null result.
Example use cases
Social share preview title check
“What og:title would show up if someone shared https://techcrunch.com/2024/01/ai-news on Twitter or Facebook?”
SEO audit for Open Graph tags
“I'm auditing our landing page — can you pull the og:title from https://mycompany.com/landing and tell me what it says?”
Scrape og:title from raw HTML
“I have some raw HTML here — can you extract the og:title meta property from it? Here it is: <html><head><meta property="og:title" content="My Product Launch"/></head></html>”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-og-title?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the og:title Open Graph meta property from a webpage or HTML snippet, particularly when you want the title that would appear in social media link previews. Prefer the free sandbox POST /v1/sandbox/xpath-og-title endpoint for testing. Choose this over generic CSS selector or full HTML scraping endpoints when only the og:title value is needed, since it is cheaper and purpose-built for this single extraction.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with network error
- No og:title meta tag present in the page — returns empty or null
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security reasons
- HTML too large (over 200,000 characters) — request rejected
- Malformed HTML where XPath cannot parse the document — extraction may fail or return empty
- Invalid or inaccessible URL format — validation error
