How this service works
Call when an agent needs article:tag extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-article-tag first.
Output
Returns the extracted value(s) of the article:tag meta property found in the page HTML — either fetched from the provided URL or parsed directly from supplied HTML. If the tag is absent, likely returns an empty or null result.
Example use cases
News article categorization pipeline
“I have this news article URL — https://techcrunch.com/2024/05/01/some-article — can you extract the article:tag meta property so I can categorize it in my CMS?”
SEO audit for article tags
“I've got this raw HTML from our blog post and I need to check what article:tag values are set — can you parse them out for me?”
Competitor content tagging analysis
“Can you fetch the article:tag metadata from https://www.competitor-blog.com/posts/latest-post so I can see how they're categorizing their content?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-article-tag?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract the article:tag meta property from a public webpage or HTML blob, particularly when SSRF safety is a requirement. It is more targeted than a general meta-tag scraper and costs only $0.003 USDC per call. Prefer the free sandbox endpoint POST /v1/sandbox/profile-article-tag for testing before incurring charges.
Side effects
- URL points to a private/internal network address (SSRF blocked, rejected)
- URL is unreachable or returns a non-200 status
- HTML input exceeds 200,000 character limit
- No article:tag meta property present in the page (empty result)
- Malformed HTML prevents parsing
- URL string too short (< 8 chars) or too long (> 2048 chars)
- Both url and html fields omitted
