agentshelf.syntexa.ch XPath iframe src Extractor

Use this endpoint when you need to extract iframe src attributes specifically via XPath from a public webpage or raw HTML, and you want SSRF-safe fetching. Prefer this over CSS-selector-based alternatives when XPath precision is needed. Use the unpaid sandbox variant (/v1/sandbox/xpath-iframe-src) first when available to avoid the $0.007 USDC cost.

• URL is unreachable or returns non-200 status — extraction fails with an error
• SSRF-blocked URL (private IP ranges, internal hostnames) — request rejected for security
• HTML input exceeds 200,000 character limit — rejected with validation error
• No iframe elements found on the page — returns empty array
• Malformed or unparseable HTML — may return partial results or error
• URL parameter too short (under 8 chars) or too long (over 2048 chars) — validation error
