How this service works
Table header cells — Duplicate value report: Duplicate value report for Table header cells. 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 value report result.
Output
A bounded duplicate value report listing table header (`<th>`) cells that contain repeated attribute values or text terms, including which values are duplicated and where they appear in the parsed HTML. Result is a single structured report object.
Example use cases
Audit accessibility IDs in product tables
“Scan https://shop.example.com/products for duplicate 'id' attributes on table header cells — I need to make sure no two th elements share the same id value, especially ones containing 'product'.”
Detect repeated column headers in pasted HTML
“I have some raw HTML with a data table — can you check it for any th cells that have duplicate 'class' attribute values? Here's the HTML: <!doctype html><html><body><table><tr><th class='col'>Name</th><th class='col'>Price</th></tr></table></body></html>”
Validate header uniqueness before publishing report
“Before I publish this report page, check https://internal.example.com/report for any table header cells whose 'scope' attribute appears more than once — flag any duplicates so I can fix them.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-table-headers-duplicates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to specifically detect duplicate attribute values or text content within HTML `<th>` (table header) elements, either from a live URL or raw HTML. It is purpose-built for header-cell duplicate detection with configurable attribute targeting, making it more precise than general HTML duplicate checkers. Prefer it for accessibility audits (duplicate ids), SEO checks, and data quality validation on HTML tables where static content is sufficient.
Side effects
- URL is unreachable or returns non-200 status — parse fails with error
- HTML exceeds 100,000 character limit — request rejected
- Attribute name does not match pattern `^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$` — validation error
- No `<th>` elements found in the provided HTML — empty report returned
- JavaScript-rendered content not present — static parser misses dynamically generated headers
- Both url and html are empty — ambiguous input, likely error or empty result
