agentshelf.syntexa.ch OG Image XPath Extractor

Choose this endpoint when you need specifically the og:image Open Graph image URL from a webpage or HTML snippet with SSRF safety guarantees. It is purpose-built for this single XPath query, making it more reliable and cheaper than a general-purpose scraper. Use when you already have raw HTML and want to avoid an extra fetch, or when you need the social preview image URL for link enrichment, content aggregation, or metadata pipelines.

• No og:image meta tag present on the page — returns empty or null result
• SSRF-blocked URL (private/internal IP ranges) — request rejected for security reasons
• URL fetch timeout or unreachable host — returns error
• HTML input exceeds 200,000 character limit — rejected
• URL shorter than 8 characters or longer than 2048 characters — validation error
• Malformed HTML that cannot be parsed via XPath — returns empty result
