How this service works
Call when an agent needs link rel=license hrefs extracted from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/profile-rel-license first.
Output
A list of href values from all link[rel=license] elements found in the provided page or HTML. May return an empty list if no such link tags are present.
Example use cases
License check for content reuse
“Check this article at https://creativecommons.org/licenses/by/4.0/deed.en and extract any link rel='license' href so I know if I can legally reuse the content.”
HTML snippet license extraction
“I have some raw HTML from a scrape — can you parse it and pull out any link rel='license' hrefs? Here's the HTML: <html><head><link rel='license' href='https://opensource.org/licenses/MIT'/></head><body></body></html>”
Verify license declaration on publisher site
“I need to verify whether this publisher page at https://news.example.com/story/123 has a license declared in its HTML link tags — can you extract the rel=license href if one exists?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-rel-license?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover license declarations embedded in a webpage's HTML link tags (rel=license), either by providing a public URL to fetch or by supplying raw HTML directly. Prefer this over general-purpose web scrapers when you specifically need license link metadata and want an SSRF-safe, deterministic extraction at low cost ($0.001 USDC).
Side effects
- URL is not publicly accessible or returns a non-200 status — extraction fails with an error
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security reasons
- HTML exceeds 200,000 character limit — request rejected
- URL parameter exceeds 2,048 characters — request rejected
- Page has no link[rel=license] elements — returns empty result
- Malformed HTML that cannot be parsed — may return empty or partial results
