How this service works
Call when an agent needs article:author extracted from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/profile-article-author first.
Output
Returns the extracted article:author value from the page's meta tags or structured HTML. This typically includes the author's name as declared in the page's metadata. If no article:author is found, the response will indicate no match.
Example use cases
Author attribution for news aggregator
“I'm building a news feed and need to credit the right author — can you pull the article:author from this page: https://techcrunch.com/2024/05/01/some-article/ ?”
Content audit across blog posts
“I have this HTML from a blog post and I need to know who authored it — can you extract the article:author field from this HTML for me?”
Research citation tool
“I want to properly cite this article — can you grab the author name from https://www.theguardian.com/technology/2024/some-article so I can include it in my bibliography?”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-article-author?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to specifically extract the article:author metadata field from a web page or HTML snippet in a safe, sandboxed way. It is ideal for content pipelines, news aggregators, citation tools, or any workflow that requires reliable author attribution from article pages. Prefer the free sandbox endpoint (/v1/sandbox/profile-article-author) for testing. Use this paid endpoint ($0.001 USDC) for production workloads where SSRF safety and reliability are required.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page does not contain an article:author meta tag — returns empty or null result
- HTML content exceeds 200,000 character limit — request rejected
- URL shorter than 8 characters or longer than 2048 characters — validation error
- SSRF-blocked URL (private IP ranges, localhost) — request rejected for safety
- Malformed HTML that cannot be parsed — may return empty result
