How this service works
Unordered lists — Duplicate attribute values: Duplicate attribute values for Unordered lists. 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 set identifying duplicate attribute values found across unordered list elements in the parsed HTML, including the specific attribute, its repeated value, and the matching list elements — filtered by the provided search term and attribute name.
Example use cases
Accessibility audit for duplicate IDs
“Check this HTML page at https://mysite.com/menu for any unordered list elements that have duplicate 'id' attribute values — I need to make sure no two lists share the same id, especially ones related to 'navigation'.”
CSS class conflict detection
“I have an HTML snippet with several ul elements all using the word 'product' in their content — can you scan it for duplicate 'class' attribute values across those lists? Here's the HTML: <!doctype html><html><body><ul class='product-list'><li>Item A</li></ul><ul class='product-list'><li>Item B</li></ul></body></html>”
Data attribute deduplication check
“Go to https://shop.example.com/categories and find any unordered lists that have duplicate 'data-section' attribute values matching the value 'featured', especially lists mentioning 'sale' items.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-unordered-lists-attribute-duplicates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, static HTML parsing specifically for duplicate attribute value detection within unordered list elements, especially as part of a front-end audit, accessibility check, or HTML quality assurance pipeline. It is ideal when you already have the HTML or a public URL, do not need JavaScript rendering, and want a focused, inexpensive ($0.01 USDC) single-operation result scoped to list markup.
Side effects
- URL is unreachable or returns non-200 status — endpoint may return an error or empty result
- HTML content exceeds 100,000 character limit — request will be rejected
- No unordered lists found in parsed HTML — returns empty duplicate set
- JavaScript-rendered content not captured — static-only parsing may miss dynamic lists
- Invalid attribute name format (must match pattern ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$) — validation error returned
- URL and HTML both omitted — endpoint requires at least one input source
