How this service works
Call when an agent needs link rel=author hrefs extracted from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/profile-rel-author first.
Output
A list of href values found in link[rel=author] elements on the page or within the provided HTML. May be empty if no such links are present.
Example use cases
Identify article author profile link
“Go to https://techcrunch.com/2024/01/15/some-story/ and pull out any link rel=author hrefs so I can find the author's profile page.”
Parse author attribution from raw HTML
“I have this HTML from a scraped page — can you find all the rel=author href links in it and return them? Here's the HTML: <html><head><link rel="author" href="https://example.com/authors/jane-doe"/></head><body>...</body></html>”
Audit author metadata across a page
“Check https://medium.com/@someauthor/my-post-abc123 and extract all link elements with rel=author so I can verify the author attribution is correctly set.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-rel-author?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover author attribution links embedded as link[rel=author] in a page's HTML head, either by supplying a URL for live fetching or providing raw HTML directly. Prefer the free sandbox endpoint (/v1/sandbox/profile-rel-author) for testing; use this paid endpoint for production workloads where SSRF-safe, reliable extraction is needed.
Side effects
- URL is unreachable or returns non-200 status — no hrefs returned or error response
- HTML input exceeds 200,000 character limit — request rejected
- URL blocked due to SSRF safety rules (private IP ranges, localhost) — error returned
- Malformed or missing URL and HTML fields — validation error
- Page has no link[rel=author] elements — empty result returned
