How this service works
Call when an agent needs the meta author extracted from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/profile-meta-author first.
Output
Returns the value of the HTML <meta name='author'> tag extracted from the provided URL (fetched SSRF-safely) or raw HTML string. If no author meta tag is present, the response will indicate absence.
Example use cases
Article authorship attribution pipeline
“I have this article URL — https://techblog.example.com/2024/ai-trends — can you pull out the meta author so I know who wrote it?”
HTML snippet author lookup
“I've got some raw HTML from a page I scraped. Can you find the meta author value in it?”
Content audit for author metadata
“Check this URL https://news.example.com/story/456 and tell me what author name is set in the meta tags.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-meta-author?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need only the meta author value from a page and want a cheap ($0.006 USDC), focused extraction rather than a full-page scrape. Prefer the free sandbox POST /v1/sandbox/profile-meta-author for testing. Choose this over general HTML parsers when SSRF safety is required and you are operating in an agentic pipeline that needs reliable, single-field extraction.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page has no meta author tag — returns empty or null result
- Provided HTML exceeds 200,000 character limit — request rejected
- URL is blocked by SSRF protection rules — request rejected
- Malformed URL or HTML below minimum length — validation error
