How this service works
Articles — Duplicate attribute values: Duplicate attribute values for Articles. One public HTTPS page or supplied HTML; static parsing, no JavaScript rendering, login or access bypass. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded duplicate attribute values result.
Output
Returns a bounded result indicating whether the specified attribute value appears more than once among article elements on the scanned page or HTML, including the duplicate occurrences found, their context, and comparison against previously seen attribute value texts.
Example use cases
SEO audit for duplicate article IDs
“Scan https://mystore.com/blog for any article tags where the 'id' attribute value appears more than once — I'm looking for duplicates related to the term 'review' and want to know if 'product-review' shows up multiple times.”
Content management deduplication check
“I have this HTML snippet from our CMS — can you check whether any article elements have duplicate 'data-kind' attribute values for the term 'guide'? Here's the HTML: <!doctype html><html><body><article data-kind="guide">Guide A</article><article data-kind="guide">Guide B</article></body></html>”
Validate unique article identifiers before publish
“Before we publish, check this page at https://news.example.com/articles for any articles sharing the same 'data-id' attribute value — I need to confirm 'article-42' isn't duplicated anywhere.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-articles-attribute-duplicates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, static HTML parsing to detect duplicate attribute values specifically within article elements, without JavaScript rendering or login. It is ideal for quick SEO audits, content integrity checks, or pre-publish validation where the content is publicly accessible or can be supplied directly as HTML. Prefer it over full-site crawlers when you only need a single page scanned for a targeted attribute duplication check at minimal cost ($0.01 USDC).
Side effects
- Invalid or unreachable URL returns an error with no parsed result
- HTML exceeding 100,000 characters is rejected
- Attribute name not matching the pattern ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$ causes a validation error
- No article elements found on the page returns an empty or null result
- JavaScript-rendered content not captured since only static HTML parsing is used
- Payment not processed results in 402 response with no data returned
