How this service works
Call when an agent needs blank-target anchor hrefs via a[target='_blank'] from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/css-external first.
Output
Returns a list of href attribute values from all anchor elements with target='_blank' found in the provided URL's page or raw HTML content. Results are SSRF-safe, meaning server-side request forgery attack vectors are mitigated.
Example use cases
Audit outbound links on landing page
“Pull all the external links that open in a new tab from our landing page at https://acme.com — I want to see every href with target='_blank' so I can audit where we're sending visitors.”
Extract partner links from HTML content
“I have some raw HTML from a partner directory page — can you parse it and give me all the anchor hrefs that have target='_blank' set? Here's the HTML: <div>...”
Monitor third-party links on blog post
“Check https://myblog.com/post/top-tools and give me all the outbound links that open in a new tab — I want to make sure none of them are going to broken or sketchy sites.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-external?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract external links that open in new tabs (a[target='_blank']) from a public URL or raw HTML. It is SSRF-safe, making it suitable for agent pipelines that process user-supplied URLs. Prefer the unpaid POST /v1/sandbox/css-external endpoint first if available; fall back to this paid endpoint when sandbox is unavailable or rate-limited.
Side effects
- URL is unreachable or returns non-200 status — endpoint may return an error or empty result
- URL points to a private/internal network address — blocked by SSRF protection
- HTML input exceeds 200,000 character limit — request rejected
- No blank-target anchors found on the page — returns empty list
- Malformed HTML may cause incomplete or unexpected parsing results
