How this service works
Call when an agent needs icon hrefs via link[rel='icon'] from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/css-link-icon first.
Output
Returns the href value(s) from link[rel='icon'] elements found in the fetched page or provided HTML. Typically a URL path or data URI pointing to the site's favicon or icon file.
Example use cases
Brand favicon discovery for directory
“I'm building a company directory — can you grab the favicon icon href from https://stripe.com so I can show their logo next to their listing?”
Icon extraction from pasted HTML
“I have this HTML snippet from a webpage — can you extract the icon href from the link rel icon tags in it?”
Verify site icon for brand monitoring
“Can you fetch the icon link from https://shopify.com so I can check what favicon URL they're currently using?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-link-icon?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract a site's favicon or icon URL from either a live public page or a known HTML string, without implementing your own HTML parser. It is SSRF-safe, making it suitable for agent pipelines that fetch arbitrary user-supplied URLs. Prefer the free sandbox version (/v1/sandbox/css-link-icon) first if available; use this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- URL not reachable or returns non-200 status — no icon href returned
- No link[rel='icon'] element present in the HTML — empty result
- SSRF-blocked URL (private IP ranges, localhost) — request rejected
- HTML input exceeds 200,000 character limit — request rejected
- URL longer than 2048 characters — validation error
- Malformed HTML with no parseable head section — no results
