“For each of these competitor sites, I need the icon href from their homepage — start with shopify.com and extract the link rel='icon' href value.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-icon-href?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the href of a <link rel='icon'> element via XPath from a public page or raw HTML. It is SSRF-safe, making it suitable for untrusted URLs. Prefer the free sandbox variant (/v1/sandbox/xpath-icon-href) first if available; use this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- No link rel='icon' element found — returns null or empty result
- URL is unreachable or returns non-200 status — fetch error
- HTML exceeds 200,000 character limit — input too large error
- URL is blocked due to SSRF safety rules — access denied
- Malformed URL input — validation error
